Conferences, Lectures, & Seminars
Speaker: Dr. Placid M. Ferreira, University of Illinois at Urbana-Champaign
Talk Title: Solid Ionics-Based Nanomanufacturing
Abstract: Mechanics and transport at the micro- and nanoscale offer a rich set of controllable phenomena that can be exploited for the development of manufacturing processes, compatible with these scales. Here, we exploit ionic transport in solids as the basis of highly controllable, efficient, high-resolution, high throughput nanomanufacturing processes for producing metallic (specifically silver and copper) nanostructures. This talk will focus on the exploitation of the high room-temperature ionic conductivity of silver and copper-based superionic glasses as the basis of subtractive and additive nano-manufacturing processes such as superionic imprinting/stamping, roll patterning and direct writing. Taking a traditional manufacturing perspective, the talk will discuss tooling and tool materials; process characterization and rates; and tool wear with such processes. Applications and future directions for solid ionics-based nanomanufacturing processes will also be discussed.

Talk Title: Skin-like, scalable, and accessible wearables for mental health
Abstract: Worldwide, 615 million people suffer from the common mental disorders of depression and anxiety. Yet, there is no existing technology that accurately and objectively monitors mental health. The obstacles towards mental health care are complex and multi-faceted: social stigma, high cost, and limited or no access to local care - all hinder patients suffering from mental health conditions to seek out and receive help. To address this chronic need, using recent advances in electronic-skin and wearable technologies, we designed a wearable that continuously measures physiological parameters linked to chronic stress and other mental health and wellness conditions, namely, heart rate variability, skin conductance, sweat rate, and the stress hormone, cortisol. We used additive manufacturing and flexible hybrid electronics to make the device scalable and low-cost. Utilizing the sensor data and analytics, we can characterize mental states quantitatively, allowing the capability to prevent and treat mental illness irrespective of the local environment. In this talk, I will demonstrate the first-of-its-kind wearable for mental health and present a multi-part study that combines both user-centered design and engineering-centered data collection to inform future design efforts for mental health wearables. Such wearable devices, in conjunction with mobile technologies, enable the possibility of remote care, which can allow discrete monitoring, potentially circumventing the stigma often associated with mental health treatment. Overall, in this talk, I will discuss engineering innovations in medical devices to address one of the most pressing global health burdens.

Computer Science
Conferences, Lectures, & Seminars
Speaker: Sanmi (Oluwasanmi) Koyejo, University of Illinois at Urbana-Champaign
Talk Title: The Measurement and Mismeasurement of Trustworthy ML
Abstract: Across healthcare, science, and engineering, we increasingly employ machine learning (ML) to automate decision-making that, in turn, affects our lives in profound ways. However, ML can fail, with significant and long-lasting consequences. Reliably measuring such failures is the first step towards building robust and trustworthy learning machines. Consider algorithmic fairness, where widely-deployed fairness metrics can exacerbate group disparities and result in discriminatory outcomes. Moreover, existing metrics are often incompatible. Hence, selecting fairness metrics is an open problem. Measurement is also crucial for robustness, particularly in federated learning with error-prone devices. Here, once again, models constructed using well-accepted robustness metrics can fail. Across ML applications, the dire consequences of mismeasurement are a recurring theme. This talk will outline emerging strategies for addressing the measurement gap in ML and how this impacts trustworthiness.
Biography: Sanmi (Oluwasanmi) Koyejo is an Assistant Professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign. Koyejo's research interests are in developing the principles and practice of trustworthy machine learning. Additionally, Koyejo focuses on applications to neuroscience and healthcare. Koyejo completed his Ph.D. in Electrical Engineering at the University of Texas at Austin, advised by Joydeep Ghosh, and completed postdoctoral research at Stanford University. His postdoctoral research was primarily with Russell A. Poldrack and Pradeep Ravikumar. Koyejo has been the recipient of several awards, including a best paper award from the conference on uncertainty in artificial intelligence (UAI), a Sloan Fellowship, a Kavli Fellowship, an IJCAI early career spotlight, and a trainee award from the Organization for Human Brain Mapping (OHBM).

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Karan Mehta, ETH Zurich
Talk Title: Integrated photonic and atomic quantum systems
Abstract: Practical and useful quantum information processing requires significant advances over current systems in error rates and robustness of basic operations, and at the same time in scale. The high coherence and precise control possible with trapped atomic ion qubits are promising for long-term systems, but the optics required pose a major challenge in scaling.
Interfacing low-noise atomic qubits with scalable integrated photonics [1] is a promising route forward, enabling practical extensibility while simultaneously lending robustness to noise.
Foundry-fabricated ion trap devices with integrated waveguide optical delivery have recently allowed us to realize multi-ion entangling quantum logic with fidelities competitive with the highest achieved across qubit platforms [2]. Aside from the stability and scalability afforded by these techniques, I will discuss how they allow generation of optical field profiles enabling new physical operations, new photonics motivated by atomic systems broadly, and additional possibilities for such techniques to advance future experiments in areas including sensing and precision metrology.

CS Colloquium: Heni Ben Amor (Arizona State University) - Human-Robot Interactive Collaboration and Communication
Thu, Apr 08, 2021 @ 04:00 PM - 05:20 PM
Computer Science
Conferences, Lectures, & Seminars
Speaker: Heni Ben Amor, Arizona State University
Talk Title: Human-Robot Interactive Collaboration and Communication
Series: Computer Science Colloquium
Abstract: Autonomous and anthropomorphic robots are poised to play a critical role in manufacturing, healthcare and the services industry in the near future. However, for this vision to become a reality, robots need to efficiently communicate and physically interact with their human partners. Rather than traditional remote controls and programming languages, adaptive and transparent techniques for human-robot collaboration are needed. In particular, robots may need to interpret implicit behavioral cues or explicit instructions and, in turn, generate appropriate responses. In this talk, I will present ongoing work which leverages machine learning (ML), natural language processing and virtual reality to create different modalities for humans and machines to engage in effortless and natural interactions. To this end, I will describe Bayesian Interaction Primitives - an approach for motor skill learning and spatio-temporal modelling in physical human-robot collaboration tasks. Further, I will discuss our recent work on language-conditioned imitation learning and self-supervised learning in interactive tasks. The talk will also cover techniques that enable robots to communicate information back to the human partner via mixed reality projections. To demonstrate these techniques, I will present applications in prosthetics, social robotics, and collaborative assembly.

Those features are critical for advancing photonic technologies in both classical and quantum domains.
In this talk, I will discuss silicon-based and thin-film lithium niobate (LN)-based photonic devices, which leverage the combination of Kerr and second-order nonlinearities, along with electro-optic (EO) and piezoelectric effects to achieve highly efficient and controllable light-matter interactions at extremely compact footprints. I will talk about the first mode-locked Kerr frequency combs in the mid-infrared regime and dual-comb spectroscopy technique for ultrafast molecular sensing, based on silicon microresonators. Furthermore, I will discuss a novel class of silicon-nitride-based optical parametric oscillators and its experimental realization for building a true quantum random number generator and a spatially multiplexed nanophotonic spin glasses system for coherent photonic computing. Thirdly, I will talk about the emerging LN optoelectronic platform and show the developments of several novel EO devices and circuits for femtosecond pulse lasers, frequency shifters, and electro-optic frequency combs. Lastly, I will discuss the potential of nonlinear photonic platform for scaling up and accelerating classical and quantum technologies in molecular sensing, photonic computing, information processing and communication networks.

Talk Title: Freeform Structural Topology-Optimized Design for Advanced Manufacturing
Abstract: Recent years have seen a rapid development within manufacturing technologies across length scales, easing the fabrication of increasingly complex material architectures, components and structures. As a consequence, there is now a need for novel engineering design methods that match the new manufacturing paradigm. Topology optimization offers a means to leverage the advanced manufacturing possibilities. It is a free-form design approach in which a formal optimization problem is posed and solved using mathematical programming. Although manufacturing has been revolutionized, there are still fabrication limitations. This talk focuses on the need for identifying the relevant material behaviors and manufacturing constraints and incorporating them within the design process.
Recently, a large research focus has been on embedding the characteristics of 3D printing into topology optimization algorithms. This talk presents the first algorithm that incorporates the discrete nozzle size restrictions associated with material extrusion 3D printing processes such as fused Fused Filament Fabrication FFF and concrete 3D printing. The extrusion printing process consists of a nozzle that moves across the build plate and deposits the extruded material on a 2D slice of the design. If the nozzle has a discrete size, the thickness of any member must consist of a discrete number of nozzle passes. This work uses a density-based topology optimization approach in which the manufacturing constraint is implicitly embedded in the filtering operation. Design solutions are shown to fulfill the nozzle restriction constraint on several benchmark examples.
Despite the advances in construction technologies, there has been little research focused on developments and application of topology optimization to civil structures. This talk will introduce and discuss design frameworks for structural systems and components made of both timber-steel and reinforced concrete. A framework to design timber-steel trusses with minimized embodied carbon will be presented. Additionally, designs for plain and reinforced concrete beams are obtained, constructed and experimentally tested in efforts to show how topology-optimized designs can achieve performance improvements without requiring a high structural complexity.
Biography: Josephine Carstensen is an Assistant Professor in the Department Civil and Environment Engineering at MIT. She leads the top-ad research group and her research revolve around the engineering question of how we design the structures of the future? Her work spans from development of computational design frameworks for various structural types and design scenarios over experimental investigations that are used to inform necessary algorithmic considerations.
Dr. Carstensen is a recipient of the National Science Foundation CAREER award 2021. She received her PhD from Johns Hopkins University in 2017 and holds a B.Sc. and a M.Sc. from the Technical University of Denmark.

Speaker: Tuomas Sandholm, Carnegie Mellon University, Strategy Robot, Inc., Optimized Markets, Inc., Strategic Machine, Inc.
Talk Title: What Can and Should Humans Contribute to Superhuman AIs?
Series: Computer Science Distinguished Lecture Series
Abstract: I will discuss what humans can and should contribute to superhuman AIs-”not general ones intended to be like humans, but ones for specific applications that make the world a better place. I will discuss how the application should drive research. I will present extensive experiences from having fielded superhuman AIs for combinatorial markets, organ exchanges, and imperfect-information game settings. I will discuss inventing and scoping novel AI applications. I will discuss how humans should supply the value framework while leaving policy optimization and combinatorics for AI. I will cover a framework that separates those ends and means, and conducts future-aware optimization in very-large-scale dynamic problems in a scalable way. I will wonder about the future of science when theorems (not just proofs) and empirical theories need to be so long that they are beyond human comprehension. I will discuss human overconfidence in humans over AI. I will discuss what explainability could be and why in many AI applications it should not be required. Finally, I will suggest flipping ethics around from an ex post discussion activity to a system-design discipline that I coin pre-design ethics.

Talk Title: Scalable Functional Synthesis: The Child of Perfect Marriage between Machine Learning and Formal Methods
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Don't we all dream of the perfect assistant whom we can just tell what to do, and the assistant can figure out how to accomplish the tasks? Formally, given a specification F(X, Y) over the set of input variables X and output variables Y, we want the assistant, aka functional synthesis engine, to design a function G such that (X, Y=G(X)) satisfies F. Functional synthesis has been studied for over 150 years, dating back to Boole in 1850s and yet scalability remains a core challenge. Motivated by progress in machine learning, we design a new algorithmic framework, Manthan, which views functional synthesis as a classification problem, relying on advances in constrained sampling for data generation, and advances in automated reasoning for a novel proof-guided refinement and provable verification. On an extensive and rigorous evaluation over 609 benchmarks, we demonstrate that Manthan significantly improves upon the current state of the art. The significant performance improvements, along with our detailed analysis, highlights several interesting avenues of future work at the intersection of machine learning, constrained sampling, and automated reasoning.

Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Nina Balke , Oak Ridge National Laboratory
Talk Title: A Nanoscale View on Electromechanical Phenomena
Abstract: The ability to transform electrical energy into mechanical energy and vice versa is the foundation to many technologies in the area of information and energy, such as sensors, piezotronics, energy harvesting, piezoelectric, electrochemical, and polymer actuators, and artificial muscles. Despite the importance of electromechanical phenomena and numerous applications, fundamental interdisciplinary studies needed to understand, and control electromechanical phenomena on the nanoscale are lacking. Atomic force microscopy (AFM) is well suited to measure local volume changes in the picometer range and has a lateral resolution of 10s of nanometer which makes this an ideal technique to address electromechanical phenomena on the nanoscale. Despite the technical advances and the development of new SPM-based characterization techniques, the quantification of functional material parameters based on electromechanical phenomena is still elusive. The lack of quantitative and accurate measurement can also lead to the misinterpretation of relevant material physics. Only if quantitative material parameters can be extracted, can a correlation of nanoscale structure-function relationships be derived, and AFM can be integrated with techniques probing smaller or larger length and time scales as well as theoretical efforts for a full information integration across different disciplines. I will give an overview over which electromechanical phenomena can be probed quantitatively including electro-chemo-mechanical coupling to understand local electrochemical reactions and processes in electrochemical capacitors. Then I will talk in depth about AFM and ferroelectric materials and how the quantitative measurement of piezoelectric material properties led to the discovery of layered 2D van der Waals ferroelectrics with highly unusual material properties and functionalities based on the presence of four polar phases and high ion conductivity. These materials demonstrate, for the first time, how physical order parameter can be controlled by ionic degrees of freedom which will open new concepts for functional heterostructures and electronic devices.

NL SEMINAR-Universal linguistic inductive biases via meta learning
Thu, Apr 15, 2021 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: R. Thomas McCoy, JHU
Talk Title: Universal linguistic inductive biases via meta learning
Series: NL Seminar
Abstract: Despite their impressive scores on NLP leaderboards, current neural models fall short of humans in two major ways. They require massive amounts of training data, and they generalize poorly to novel types of examples. To address these problems, we propose an approach for giving targeted linguistic inductive biases to a model, where inductive biases are factors that affect how a learner generalizes. Our approach imparts inductive biases using meta learning, a procedure through which the model discovers how to acquire new languages more quickly via exposure to many possible languages. By controlling the properties of the languages used during meta learning, we can control the inductive biases that meta learning imparts. Using a case study from phonology, we show how this approach enables faster learning and more robust generalization.
Biography: Tom McCoy is a PhD student in the Johns Hopkins Cognitive Science department, advised by Tal Linzen and Paul Smolensky. He studies the linguistic abilities of neural networks, focusing on inductive biases the topic of this talk as well as compositional structure: How can neural networks use their continuous vector representations to encode phrases and sentences?

Advanced Manufacturing Seminar
Fri, Apr 16, 2021 @ 10:00 AM - 11:30 AM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Denis Cormier, Earl W. Brinkman Professor, Rochester Institute of Technology
Talk Title: Metal Additive Manufacturing Via Jetting of Molten Metal Droplets
Abstract: This seminar will introduce attendees to an emerging metal additive manufacturing process that produces parts via on-demand jetting of molten metal droplets. Unlike traditional metal additive manufacturing processes such as powder bed fusion or binder jetting, the droplet jetting process uses wire, rather than powder, as the feedstock material. This greatly reduces cost and safety concerns. The absence of a powder bed also reduces feedstock carrying costs and eliminates complicated lot tracing procedures associated with blending of new and used powders. Process parameters such as drop size, jetting temperature, drop spacing, and jetting frequency all influence the dimensional accuracy, density, and mechanical properties of fabricated parts. An open architecture droplet jetting machine from Xerox (formerly Vader Systems) is used to demonstrate the influence of both process parameters and toolpath generation strategies on geometric accuracy, density, and microstructure of aluminum alloys.
Biography: Dr. Denis Cormier is the Earl W. Brinkman Professor of Industrial and Systems Engineering at Rochester Institute of Technology where he directs the New York State funded AMPrint Center for Advanced Technology. Dr. Cormier has worked in the area of 3D printing and additive manufacturing for 25 years. Since joining RIT in 2009, his research has focused on technologies such as multi-material inkjet deposition, direct-write processes including aerosol printing and microdispensing, and pulsed photonic sintering. Most recently, he has focused on development of a liquid metal droplet jetting additive manufacturing process. Prior to joining RIT, he was a professor at North Carolina State University from 1994 to 2009.

CS Colloquium: Alice Xiang (Sony AI) - Algorithmic Fairness and the Law
Fri, Apr 23, 2021 @ 10:00 AM - 11:00 AM
Computer Science
Conferences, Lectures, & Seminars
Speaker: Alice Xiang, Sony AI
Talk Title: Algorithmic Fairness and the Law
Series: Computer Science Colloquium
Abstract: What does it mean for an algorithm or decision-making process to be fair? When making decisions using data, how do we account for historical biases or systemic inequalities? While the algorithmic fairness literature is comparatively nascent, these are questions the law has long grappled with. This talk will provide an overview of the algorithmic fairness literature and connections with anti-discrimination jurisprudence. In particular, this talk will discuss the tension between the use of protected class attributes to mitigate algorithmic bias and the law's preference for efforts to address discrimination that are blind or neutral to protected class attributes. Divergences like this between legal compatibility and technical feasibility are challenges that will need to be addressed in order to deploy algorithmic fairness methods in practice.
This lecture satisfies requirements for CSCI 591: Research Colloquium.
Biography: Alice Xiang is a Senior Research Scientist at Sony AI, where she leads research on responsible AI. Alice previously worked as the Head of Fairness, Transparency, and Accountability Research at the Partnership on AI, where she led a team of interdisciplinary researchers and a portfolio of multi-stakeholder research initiatives. She also served as a Visiting Scholar at Tsinghua University's Yau Mathematical Sciences Center. She was recognized as one of the 100 Brilliant Women in AI Ethics, and has been quoted in the Wall Street Journal, MIT Tech Review, Fortune, and others, for her work on algorithmic bias and transparency, criminal justice risk assessment tools, and AI ethics. Alice holds a Juris Doctor from Yale Law School, a Master's in Development Economics from Oxford, a Master's in Statistics from Harvard, and a Bachelor's in Economics from Harvard.
