Talk Title: Diffractive Optical Networks & Computational Imaging Without a Computer
Series: Photonics Seminar Series
Abstract: I will discuss diffractive optical networks designed by deep learning to all-optically implement various complex functions as the input light diffracts through spatially-engineered surfaces. These diffractive processors designed by deep learning have various applications, e.g., all-optical image analysis, feature detection, object classification, computational imaging and seeing through diffusers, also enabling task-specific camera designs and new optical components for spatial, spectral and temporal beam shaping and spatially-controlled wavelength division multiplexing. These deep learning-designed diffractive systems can broadly impact (1) all-optical statistical inference engines, (2) computational camera and microscope designs and (3) inverse design of optical systems that are task-specific. In this talk, I will give examples of each group, enabling transformative capabilities for various applications of interest in e.g., autonomous systems, defense/security, telecommunications as well as biomedical imaging and sensing.

Conferences, Lectures, & Seminars
Speaker: Dr. Sunil Kumar Vuppala, Director, Data Science, Ericsson
Talk Title: Causal Dependencies in Multivariate Time Series
Abstract: The talk starts with a motivation for casual analysis. Correlation does not imply causation. Similarly, lack of correlation does not imply lack of causation. How can we detect causality in complex systems such as telecom networks? The talk covers 3Wh of Causality (What, why, where). It covers taxonomy of time series casual discovery, an overview of the methods and techniques such as Granger causality, Convergent Cross Mapping, information theoretic approaches, graphical approaches and ML approaches. How can we connect any observed event to possibly a set of specific causal events? Why do we need counterfactual interventions for causal intensity? The talk describes the relevance of causality in telecom domain and cover a few use cases in telecom such as Key Performance Indicator (KPI) degradation and outlier root cause analysis and hardware failures. The speaker will share sample results from simulated experiments. He will introduce a few active research topics in this space.

Conferences, Lectures, & Seminars
Speaker: Marco Panesi, University of Illinois Urbana-Champaign
Talk Title: Construction of Hydrodynamic Models for Nonequilibrium Flows: Application to Hypersonics
Abstract: The simulation of the aerothermal environment surrounding vehicles moving at hypersonic speed is a complex problem due to its multi-physics and multi-scale nature. Progress in accurately modeling these systems has been hindered by the lack of reliable physical models for the thermochemical and transport processes that dominate the dynamics of the flow. The most physically consistent description of nonequilibrium flows relies on the direct numerical solution of the kinetic equations for each internal state of the gas particles. However, for problems of interest, the exponentially large many degrees of freedom, and the wide range of spatial and temporal scales involved, make these equations unsolvable.
This talk outlines a new paradigm for constructing predictive modeling and simulation tools from a fundamental physics perspective, rejecting the empiricism that has prevented progress in modeling hypersonic flows for decades. Inspired by model reduction strategies developed in statistical physics, this work addresses the challenges of the combinatorial explosion of the possible configurations of the system,obtaining new governing equations by projecting the master equation onto a few lower-dimensional subspaces. The distribution function within each subspace is then reconstructed using the Maximum Entropy Principle, thus ensuring compliance with the Detailed Balance.
I will cover the critical aspects involved in model development: (1) using direct numerical simulationto study the fundamental physics; (2) derivation of a reduced-order set of equations that give an accurateand physical consistent description of the physics at a much-reduced computational cost: (3) Validationand uncertainty quantification.
Biography: Dr. Marco Panesi is currently a Professor in the Aerospace Engineering Department and director of the Center for Hypersonics and Entry System Studies (CHESS) at the University of Illinois at Urbana-Champaign. In 2009, he received a Ph.D. degree from the von Karman Institute for Fluid Dynamics. He completed a post-doc with the PECOS center, one of the five DOE-funded PSAAP centers, at Odens Institute.

In person attendance will be permitted for USC ISI faculty, staff, students only. Open to the public virtually via the zoom link and online.
With pre-trained transformer-based models continuously increasing in size, there is a dire need for parameter-efficient and modular transfer learning strategies. In this talk, we will touch base on adapter-based fine-tuning, where instead of fine-tuning all weights of a model, small neural network components are introduced at every layer. While the pre-trained parameters are frozen, only the newly introduced adapter weights are fine-tuned, achieving an encapsulation of the down-stream task information in designated parts of the model. We will demonstrate that adapters are modular components which can be composed for improvements on a target task and how they can be used for out of distribution generalization on the example of zero shot cross-lingual transfer. Finally, we will discuss how adding modularity during pre training can mitigate catastrophic interference and consequently lift the curse of multilinguality.
Biography: Jonas Pfeiffer is a Research Scientist at Google Research. He is interested in modular representation learning in multi task, multilingual, and multi-modal contexts, and in low resource scenarios.

Speaker: Omeed Momeni, University of California
Talk Title: Scalable Standing Wave Integrated Circuits for Reconfigurable Power Generation, Radiation and Beam Steering at mm-Wave and Terahertz Spectrum
Series: Integrated Systems
Abstract: The power generation of transistors declines as the operation frequency increases. At the same time, the
free space propagation loss increases, demanding more radiated power from the system. The loss of passive
elements in the circuit increases as well, making functions such as oscillation or radiation even more challenging. In
order to boost the limited power, multiple sources need to be coupled together in an array structure. However, the
significant loss of the coupling circuitry and phase shifters at mm-wave and terahertz frequencies hinders the
implementation of large and efficient radiator and phased arrays. Scalable standing wave array structures are
proposed based on efficient low loss coupling schemes in order to boost the power and operation bandwidth.
Furthermore, a practical approach is proposed to maximize Equivalent Isotropic Radiated Power (EIRP) of the
source by optimizing influential parameters of the radiation apparatus. Finally, we demonstrate a new phase shifting
method based on combining standing and traveling waves and show how it can achieve significantly higher
reconfigurability, phase shifting range and bandwidth. Using all these methods we present coupled-oscillators,
scalable radiator arrays, and reconfigurable phased arrays that can produce high resolution images and achieve
record beam steering range, tuning range, and output power at mm-wave and terahertz frequencies.

Speaker: Galan Moody, University of California Santa Barbara
Talk Title: Integrated Quantum Photonics Beyond Silicon
Abstract: Silicon-on-insulator has been an indispensable platform for classical and quantum photonics, but it is lacking in several aspects that are needed for the next generation of advanced quantum technologies. Beyond silicon, there is a spectrum of alternative crystalline materials-”such as compound semiconductors, lithium niobate, and 2D materials-”that have the potential to enable radically new device concepts and related quantum technologies. In this presentation, I will highlight my group's progress in developing several heterogeneous photonic platforms to address key challenges in quantum communications, networking, and distributed information processing. These include AlGaAs-on-insulator photonics for ultra-efficient entangled-pair generation, squeezing, and frequency-bin information processing; the integration of AlGaAs and 2D material single-photon sources with silicon photonics; and hybrid quantum dot devices with opto-electronic and opto-mechanical resonators for dynamic tuning and quantum transduction.
Biography: Professor Moody joined the Electrical and Computer Engineering Department at the University of California Santa Barbara in July 2019. Prior to moving to Santa Barbara, he was a Research Scientist (2015-2019) at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, USA, a National Research Council postdoctoral fellow at NIST (2013-2015), and a postdoctoral associate at the University of Texas, Austin, USA (2013). He received his PhD Degree in Physics (2013) and his BSc Degree in Engineering Physics (2008) from the University of Colorado Boulder. He is a recipient of an Air Force Young Investigator Program award (2020) and an NSF CAREER award (2021) for research on integrated quantum photonic technologies.

Conferences, Lectures, & Seminars
Speaker: Professor Allen Liu, Associate Professor in Mechanical Engineering, Biomedical Engineering, and Biophysics, University of Michigan
Talk Title: "Bottom-Up Biology": Building Synthetic Cells
Series: MFD Distinguished Lecture Series
Abstract: "Biological membranes are involved in many cellular processes including cell migration, membrane trafficking, and cell signaling. A significant amount of work has elucidated the molecular machineries that regulate dynamic membrane-based processes. In parallel, there are growing interests in recent years in trying to understand how the mechanical state of the cells is utilized as a regulatory input to control cellular processes. My lab is broadly interested in studying the mechanochemical responses and force generation of biological systems, both in cells and in cell-like systems. In this talk, I will present two directions in building cell-like systems referred to as synthetic cells. In the first part of the talk, I will describe the self-organization of the reconstituted actin network, with crosslinker proteins and molecular motor myosin, in synthetic cells. Depending on the confinement size and concentrations of actin crosslinkers, distinct actomyosin patterns emerge in the form of asters and rings and could constrict the synthetic cell. In the second part of the talk, I will describe a general synthetic cell platform that makes use of encapsulation of mammalian cell-free expression reactions to reconstitute membrane proteins for generating membrane-active synthetic cells. I will share our work on building mechanosensitive synthetic cells and ongoing work on building synthetic neurons."

Conferences, Lectures, & Seminars
Speaker: Swabha Swayamdipta, University of Southern California
Talk Title: Contextualizing Bias in Hate Speech Detection through Annotator Perspectives
Series: USC Center for Artificial Intelligence in Society (CAIS) Seminar Series
Abstract: In an increasingly online world, content moderation in social media has become immensely important. However, existing hate speech detection systems are riddled with racial biases introduced during annotation, which are reinforced and propagated by models trained on such data. In this talk, I will first present the inadequacies of current methods for debiasing hate speech detection. I will show how the subjectivity of this task design leads to debiasing failures. Next, I will focus on uncovering the origin of bias in toxic language detection. I will demonstrate how annotators' demographics and beliefs influence their toxicity ratings, and how ignoring such societal context can lead to biased outcomes. Overall, I will argue for the value of rethinking traditional the hate speech classification task, and the need for richer context in hate speech datasets.
Prof. Swayamdipta will give her talk in person at GFS 116 and we will also host the talk over Zoom.

Abstract: Deploying legged robots in real-world applications will require fast adaptation to unknown terrain and model uncertainty. Model uncertainty could come from unknown robot dynamics, external disturbances, interaction with other humans or robots, or unknown parameters of contact models or terrain properties. In this talk, I will first present our recent works on adaptive control and adaptive safety-critical control for legged locomotion adapting to substantial model uncertainty. In these results,
we focus on the application of legged robots walking rough terrain while carrying a heavy load. I will then talk about our solution on trajectory optimization that allows legged robots to adapt to a wide variety of challenging terrain. This talk will also discuss the combination of control, trajectory optimization and reinforcement learning toward achieving long-term adaptation in both control actions and trajectory planning for legged robots.

Artificial intelligence AI has shown remarkable effectiveness in knowledge seeking applications e.g., for recommendations and explanations. However, the increasing expectation of more trust, accessibility, and anthropomorphism in these AI systems requires the underlying components dialog models, LLMs, classifiers to be adaptive and adequately knowledge grounded. In reality, the outputs of the constituent models often lack commonsense, explanations, and subjectivity a long standing goal of artificial general intelligence.
In this talk, I aim to address this gap through the concept of interactive explainability, realized via three pillars knowledge, explanations, and interactions. First, I will explore the post-hoc methods to effectively inject relevant and diverse knowledge into an existing dialog model without additional training. Second, I will investigate the role of background knowledge in model reasoning, prediction, and faithfully constructing natural language explanations. Third, I will propose an interactive approach to address fairness and subjectivity in bias mitigation via feature level user interventions. Finally, I will hint at future possibilities and societal impacts of next-generation explainable interactive systems.

Dean's Seminar: Dean Gregory D. Abowd (Northeastern University) - The Internet of Materials: Rethinking the future of computing
Thu, Nov 10, 2022 @ 03:30 PM - 04:50 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Dean Gregory D. Abowd, Northeastern University
Talk Title: The Internet of Materials: Rethinking the future of computing
Series: Dean's Seminar
Abstract: If we trace how computers have evolved over the past 8 or so decades, we can certainly see the impact of increasingly sophisticated manufacturing techniques. Computers now come in many different shapes and sizes. And applications, of course, have driven the widespread adoption, so much so that it appears we have an insatiable appetite for computing, and the power that is needed to feed it. That's a problem. We must take more seriously some of the past assumptions of how we manufacture computers and what properties the constituent materials impose. In this talk, I will introduce the notion of the Internet of Materials, whereby the power, form factor, and manufacturing costs of a computational object take precedence over other functional features of that object. I will show some simple examples that highlight how we can create self-sustaining computational materials. The purpose of the talk is to motivate researchers to think creatively about the convergence of materials, manufacturing, and computing. I hope these initial, and somewhat simple, examples prompt deeper discussions on how Northeastern can become a leader in defining a complementary computing industry.
This lecture satisfies requirements for CSCI 591: Research Colloquium.

Talk Title: Toward Tbps Optical and Wireline Communication: a Circuit Design Perspective
Series: Integrated Systems
Abstract: The demand for higher data rate communication has never been greater than today. Driven by
emerging technologies particularly IoT and cloud computing, higher capacity is required both in core
networking as well as computing applications. A report by the IEEE Ethernet Bandwidth Assessment ad
hoc group stated that "global demand for network bandwidth is growing at such an alarming rate that
terabit-speed networks will be the only way to support capacity, should current trends continue through
2015". This brings new challenges for circuit designer community as higher speed and better energy
efficiency are expected from building blocks of such communication systems.
This talk starts with an introduction to the two major category of optical communication; IMDD (Intensity
Modulated Direct Detect) vs Coherent detection. Pros, cons, and application of each are discussed and the
general architecture of receivers and transmitters in these systems are given. The talk then reviews the
latest trends in the design of high-speed transimpedance amplifiers and modulator drivers. Some examples
of co-design and co-optimization with optics are presented.
Biography: Bahar Jalali-Farahani received her PhD in electrical engineering from The Ohio
State University in 2005. During her PhD program, she was working with the data
converter research group at Freescale Semiconductor in Tempe, AZ where she was
responsible for developing digital calibration techniques for high resolution data
converters. She joined the department of electrical engineering at Arizona State
University in January 2006 and continued her research on digitally assisted high
performance analog circuits, and low-power circuit techniques. From 2011 to 2014
she was with Cisco Systems working on design of high-speed components for
Silicon-Photonics-based 100Gb Ethernet. In 2014 she joined Nokia Bell Labs in NJ

Talk Title: Tackling longstanding challenges in ultrafast nonlinear optics via foreign but familiar physics
Series: Photonics Seminar Series
Abstract: Silicon-Optical nonlinearities have expanded the optics and photonics toolset for applications as diverse as high intensity laser science, quantum information processing, and the imaging and spectroscopy of biological systems. Key to many applications is use of the nonlinear polarizability of materials to couple photons between optical fields, giving rise to amplification and frequency conversion methods that expand the reach of lasers and other photon sources, both classical and non-classical. Other applications use light 'self-effects' to guide, switch, and modulate. However, optical nonlinearities are often small, and even when large enough, the spatiotemporal and spectral inhomogeneities in nonlinear optical systems can severely hamper the efficiency and bandwidth of power flow between waves.
Our group has been seeking ways to 'trick' nonlinear systems into modes of evolution that can avoid the normal limiting behaviors or to make use of unconventional nonlinear interactions. I'll discuss a few of these that possess familiar physics that are somewhat foreign to optical light pulses, such as rapid adiabatic passage in optical frequency conversion, oscillation damping in parametric (i.e., lossless) wave mixing, and nonlinear optical interactions involving coherent phonon coupling. And I will present some technologies that they can enable, including efficient parametric amplifiers, dispersion-free octave-spanning frequency up- and down-converters, strong cross-phase modulation, and the removal of spectral distinguishability.
Biography: Jeff Moses joined the faculty at Cornell University in 2014, where he leads the Ultrafast Phenomena and Technologies Group in the School of Applied and Engineering Physics. He received his B.S. from Yale and Ph.D. from Cornell, with both degrees in applied physics, and spent several years at the Optics & Quantum Electronics Group in the Research Laboratory of Electronics at MIT as a postdoctoral associate and research scientist.

Speaker: Khalid Jawed, UCLA
Talk Title: Reduced Order Modeling and Inverse Design of Flexible Structures by Machine Learning
Abstract: Recent advances in highly deformable structures necessitate simulation tools that can capture nonlinear geometry and nonlinear material. We propose machine learning, neural networks (NN) in particular, to capture this nonlinearity and solve highly nonlinear inverse problems in structural mechanics. Two representative problems will be discussed in this talk.
In the first problem, we use NN to reduce the number of variables and speed up the simulation by orders of magnitude. As a test case, we explore the dynamical simulation of a slinky, a pre-compressed elastic helix that is widely used as a toy for children. However, most often the deformation of a slinky can be fully captured by the deformation of its helix axis. Instead of simulating the entire helical structure, the axis of the helix is a reduced-order representation of this system. We use NN to store the elastic forces of the slinky in its reduced-order representation, utilizing the concept of neural ordinary differential equations. The NN is trained using data from a fine-grained 3D rod simulation called the Discrete Elastic Rods (DER). Once the elastic forces in the reduced representation are stored in the NN, force balance equations can be solved in this representation for the dynamic simulation. This results in savings in computational time without much impact on its physical accuracy.
In the second problem, we explore shape-morphing structures that spontaneously transition from planar to 3D shapes. This is a transformative technology with broad applications in soft robotics and deployable systems. However, realizing these morphing structures that can achieve certain target shapes is challenging and typically involves a painstaking process of trials and errors with complex local fabrication and actuation. We propose a rapid design approach for fully soft structures that can achieve targeted 3D shapes through a fabrication process that happens entirely on a 2D plane. By combining the strain mismatch between layers in a composite shell and locally relieving stress by creating kirigami cuts, we are able to create 3D free buckling shapes from planar fabrication. However, the large design space of the kirigami cuts and strain mismatch presents a challenging task of inverse form finding. We develop a symmetry-constrained active learning approach to learn how to explore the large design space strategically. Interestingly, we report that, given a target 3D shape, multiple design solutions exist, and our physics-guided machine learning approach can find them in a few hundred iterations. Desktop-controlled experiments and finite element simulations are in good agreement in examples ranging from peanuts to flowers.

Speaker: Yang Liu, UC Santa Cruz
Talk Title: Agency Bias in Machine Learning
Series: Machine Learning Seminar Series
Abstract: A trained machine learning model (e.g., a classifier) will ultimately observe data generated according to agents' responses. For instance, the rising literature on strategic classification concerns the setting where agents are fully rational and can best respond to a classifier in their own interests. The above interaction will lead to a distribution shift between training and deployment and will challenge the existing performance and fairness guarantees of the trained model. In this talk, I'll discuss three types of agency bias that arise due to the above interactional effects between agents and machine learning models. I'll then go over possible mitigation efforts, including our very recent works on certifying the fairness guarantees on an unknown and possibly different deployment distribution.

Machine learning models have been quite successful at emulating human intelligence but their potential as intelligence augmentation is less explored. Part of the challenge is our lack of understanding in how these models work, and this is the problem interpretability is trying to tackle. But most existing interpretability work takes models trained under the emulation paradigm and adds humans into the mix post-hoc-the human's role is largely an afterthought. In this talk, I advocate for a more pragmatic approach to interpretability and emphasize modeling the human's needs in their cooperation with AIs. In the first part, I discuss how the human-AI team can be evaluated and optimized as a unified decision-maker, and how the model can learn to explain selectively. In the second part, I discuss how human intuition measured outside of the working with an AI context can be incorporated into models and explanations. I'll conclude with a brief discussion on formulating the model's pragmatic inference about its human teammate.
Biography: Shi Feng is a postdoc at University of Chicago working with Chenhao Tan. He got his PhD from University of Maryland under Jordan Boyd-Graber. He is interested in human-AI cooperation: how machine learning can help humans make better decisions, and how humans can provide supervision more effectively. His past work focuses on natural language processing, and covers topics including interpretability, adversarial attacks, robustness, and human-in-the-loop evaluations.

ECE Seminar: Learning Efficiently in Data-Scarce Regimes

Speaker: Dr. Mohammad Rostami, Research Assistant Professor, Dept of CS / Research Lead, USC-ISI
Talk Title: Learning Efficiently in Data-Scarce Regimes
Abstract: The unprecedented processing demand, posed by the explosion of big data, challenges researchers to design efficient and adaptive machine learning algorithms that do not require persistent retraining and avoid learning redundant information. Inspired from learning techniques of intelligent biological agents, identifying transferable knowledge across learning problems has been a significant research focus to improve machine learning algorithms. In this talk, we explain how the challenges of knowledge transfer can be addressed through embedding spaces that capture and store hierarchical knowledge.
We first focus on the problem of cross-domain knowledge transfer. We explore the problem of zero-shot image classification, where the goal is to identify images from unseen classes using semantic descriptions of these classes. We train two coupled dictionaries that align visual and semantic domains via an intermediate embedding space. We then extend this idea by training deep networks that match data distributions of two visual domains in a shared cross-domain embedding space.
We then investigate the problem of cross-task knowledge transfer in sequential learning settings. Here, the goal is to identify relations and similarities of multiple machine learning tasks to improve performance across the tasks. We first address the problem of zero-shot learning in a lifelong machine learning setting, where the goal is to learn tasks with no data using high-level task descriptions. Our idea is to relate high-level task descriptors to the optimal task parameters through an embedding space. We then develop a method to overcome the problem of catastrophic forgetting within a continual learning setting of deep neural networks by enforcing the tasks to share the same distribution in the embedding space.
Finally, we focus on current research directions to expand past progress and plans for future research directions. Through this talk, we demonstrate that despite major differences, problems within the above learning scenarios can be tackled using a unifying strategy that allows transferring knowledge effectively.

Speaker: Mihaela van der Schaar, University of Cambridge
Talk Title: AI for Science: Discovering Diverse Classes of Equations in Medicine and Beyond
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Artificial Intelligence (AI) offers the promise of revolutionizing the way scientific discoveries are made and significantly accelerating their pace. This is important for numerous fields of study, including medicine. In this talk, I will present our research on AI for science over the past few years. I will start by briefly showing how we can discover closed-form prediction functions from cross-sectional data using symbolic metamodels. Then, I will introduce a new method, called D-CODE, which discovers closed-form ordinary differential equations (ODEs) from observed trajectories (longitudinal data).This method can only describe observable variables, yet many important variables in medical settings are often not observable. Hence, I will subsequently present the latent hybridisation model (LHM) that integrates a system of ODEs with machine-learned neural ODEs to fully describe the dynamics of the complex systems. However, ODEs are fundamentally inadequate to model systems with long-range dependencies or discontinuities. To solve these challenges, I will then present Neural Laplace, with which we can learn diverse classes of differential equations in the Laplace domain. I will conclude by presenting next research frontiers, including recent work on discovering partial differential questions from data (D-CIPHER). While these works are applicable in numerous scientific domains, in this talk I will illustrate the various works with examples from medicine, ranging from understanding cancer evolution to treating Covid-19. This work is joint work with Zhaozhi Qian, Krzysztof Kacprzyk and Sam Holt.

Virtual Efficient Estimation of Treatment Effect in Online Experiments
Wed, Nov 30, 2022 @ 10:00 AM - 11:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Congshan Zhang, Meta , Core Data Science Team at Meta
Talk Title: Efficient Estimation of Treatment Effect in Online Experiments
Abstract: Randomized controlled trials are commonly used by tech companies to draw causal conclusions on various product changes. The confidence intervals from these experiments, however, are usually too large due to reasons such as limited number of users, heavy-tailed outcome variables and small treatment effects. Improving estimation efficiency for randomized controlled trials is not only a scientifically interesting but also a practically relevant area of research. In this talk, I will go over a few prominent techniques in statistics to improve estimation efficiency. Basic techniques such as CUPED and more advanced methodologies based on ML and synthetic controls will be introduced.
Biography: Congshan Zhang is a research scientist on Core Data Science Team at Meta. Congshan is interested in various topics in statistics and econometrics including causal inference, machine learning and time series. Congshan holds Ph.D. in economics from Duke University. Before joining Meta, Congshan did research on financial econometrics, with a focus on nonparametric and semi-parametric inference using high-frequency data and on testing models of financial markets. His work appears in top journals of econometrics such as Journal of Econometrics and Annals of Applied Probability.

Speaker: Vikas Sindhwani, Google Brain
Talk Title: Foundation Models for Robotics
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Trained on internet-scale datasets, large language and vision models demonstrate breakthrough capabilities which until recently were thought to still be decades away in technological feasibility. Does this imply a paradigm shift in Robotics as well? If so, what is the bridge from symbols and tokens on the internet to actions in the physical world? Through a few illustrative vignettes of robotic manipulation and navigation research at Google, I will propose speculative paths towards making robots useful in human-centric spaces.

AME Seminar (Virtual)

Conferences, Lectures, & Seminars
Speaker: Sebastian Pattinson, University of Cambridge
Talk Title: Generalisable 3D Printing Error Detection and Correction via Neural Networks
Abstract: Material extrusion is the most widespread additive manufacturing method but its application in end-use products is limited by vulnerability to errors. Humans can detect errors but cannot provide continuous monitoring or real-time correction. Existing automated approaches are not generalisable across different parts, materials, and printing systems. In this talk I will discuss recent work in our lab where we train a multi-head neural network using images automatically labelled by deviation from optimal printing parameters. The automation of data acquisition and labelling allows the generation of a large and varied extrusion 3D printing dataset, containing 1.2 million images from 192 different parts labelled with printing parameters. The thus trained neural network, alongside a control loop, enables real-time detection and rapid correction of diverse errors that is effective across many different 2D and 3D geometries, materials, printers, toolpaths, and even extrusion methods.
Biography: Sebastian Pattinson is an Assistant Professor in the Department of Engineering at the University of Cambridge. His group develops 3D printers that learn how to make things better and uses these to make better medical devices. Before joining the Cambridge, Sebastian was a postdoctoral fellow in the Department of Mechanical Engineering at MIT focusing on 3D printed materials and devices. He received Ph.D. and Masters degrees in the Department of Materials Science & Metallurgy at the University of Cambridge, where he developed nanomaterial synthesis methods. His awards include a UK Academy of Medical Sciences Springboard award; US National Science Foundation postdoctoral fellowship; UK Engineering and Physical Sciences Research Council Doctoral Training Grant; MIT Translational Fellowship; and a (Google) X Moonshot Fellowship.
