    Talk Title: There Is Hope After All: Quantifying Trustworthiness in Neural Networks

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: Artificial Intelligence (AI) plays a fundamental role in the modern world, especially when used as an autonomous decision maker. One common concern nowadays is "how trustworthy the AIs are." Human operators follow a strict educational curriculum and performance assessment that could be exploited to quantify how much we entrust them. To quantify the trust of AI decision makers, we must go beyond task accuracy especially when facing limited, incomplete, misleading, controversial or noisy datasets. Toward addressing these challenges, we describe DeepTrust, a Subjective Logic (SL) inspired framework that constructs a probabilistic logic description of an AI algorithm and takes into account the trustworthiness of both dataset and inner algorithmic workings. DeepTrust identifies proper multi-layered neural network (NN) topologies that have high projected trust probabilities, even when trained with untrusted data. We show that uncertain opinion of data is not always malicious while evaluating NN's opinion and trustworthiness, whereas the disbelief opinion hurts trust the most. Also trust probability does not necessarily correlate with accuracy. DeepTrust also provides a projected trust probability of NN's prediction, which is useful when the NN generates an over-confident output under problematic datasets. These findings open new analytical avenues for designing and improving the NN topology by optimizing opinion and trustworthiness, along with accuracy, in a multi-objective optimization formulation, subject to space and time constraints.

    Speaker: Alan Mishchenko, Department of Electrical Engineering and Computer Sciences, University of California, Berkeley

    Talk Title: Circuit-Based Intrinsic Methods to Detect Overfitting

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: The focus of this talk is on intrinsic methods to detect overfitting. By intrinsic methods, we mean methods that rely only on the model and the training data, as opposed to traditional methods that rely on performance on a test set or on bounds from model complexity. We propose a family of intrinsic methods, called Counterfactual Simulation (CFS), which analyze the flow of training examples through the model by identifying and perturbing rare patterns. By applying CFS to logic circuits we get a method that has no hyper-parameters and works uniformly across different types of models such as neural networks, random forests and lookup tables. Experimentally, CFS can separate models with different levels of overfit using only their logic circuit representations without any access to the high level structure. By comparing lookup tables, neural networks, and random forests using CFS, we get insight into why neural networks generalize. The paper appeared at ICML 2020: https://people.eecs.berkeley.edu/~alanmi/publications/2020/icml20_cfs.pdf

    Conferences, Lectures, & Seminars


    Speaker: Adrian Lozano-Duran, Stanford

    Talk Title: Prediction of real-world external aerodynamics using numerical simulations

    Abstract: The use of computational fluid dynamics for external aerodynamic applications has been a key tool for aircraft design in the modern aerospace industry. In the last decades, large-eddy simulation with near-wall modeling (wall-modeled LES) has gained momentum as a cost-effective approach for both scientific research and industrial applications. In this talk, we discuss current challenges of wall-modeled LES to become a design tool for the aerospace industry. Our focus is on the working principles and performance of wall-modeled LES for external aerodynamic applications, with emphasis on realistic commercial aircrafts. We examine the computational cost to predict mean flow features and forces for a given degree of accuracy using theory and numerical simulations of the NASA Juncture Flow and the JAXA Standard Model. The vision presented here is motivated by discussions in previous AIAA workshops and the experience acquired at the Center for Turbulence Research during the last years.

    Biography: Dr. Adrian Lozano-Duran is a Postdoctoral Research Fellow at the Center for Turbulence Research at Stanford University hosted by Prof. Moin. He received his PhD in Aerospace Engineering from the Technical University of Madrid in 2015 at the Fluid Mechanics Lab. advised by Prof. Jiménez. The overarching theme of his research is physics and modeling of wall-bounded turbulence via theory and computational fluid mechanics. His work covers a wide range of topics, such as turbulence theory and modeling by machine learning, large-eddy simulation for external aerodynamics, geophysical and multiphase flows, among others.

    Conferences, Lectures, & Seminars


    Speaker: Katherine Bouman , Caltech

    Talk Title: Capturing the First Image of a Black Hole and Designing the Future of Black Hole Imaging

    Abstract: The Math Department is having a talk on Friday, September 11 at 330PM PST and invites the CS community to attend.

    This talk will present the methods and procedures used to produce the first image of a black hole from the Event Horizon Telescope, as well as discuss future developments for black hole imaging. It had been theorized for decades that a black hole would leave a "shadow" on a background of hot gas. Taking a picture of this black hole shadow would help to address a number of important scientific questions, both on the nature of black holes and the validity of general relativity. Unfortunately, due to its small size, traditional imaging approaches require an Earth-sized radio telescope. In this talk, I discuss techniques the Event Horizon Telescope Collaboration has developed to photograph a black hole using the Event Horizon Telescope, a network of telescopes scattered across the globe. Imaging a black hole's structure with this computational telescope required us to reconstruct images from sparse measurements, heavily corrupted by atmospheric error. The talk will also discuss future developments, including new imaging techniques and how we are developing machine learning methods to help design future telescope arrays.

    Speaker: Feifei Qian, Department of Electrical and Computer Engineering, University of Southern California

    Talk Title: Generating Desired Robot Movements from Complex Environments

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: Robots nowadays are expected to take on increasingly important roles in human society. However, state-of-the-art robots still struggle to move on natural terrains such as soft sand and rubble field, due to the lack of understanding of the interactions between robots and non-flat, non-rigid surfaces. In this talk, I will use a few examples from my recent work to illustrate how I use a "robophysics" approach -“ an integration of robotics, terradynamics, and locomotion biomechanics -- to create interaction models and frameworks that can guide design and control of bio-inspired robots to enable effective movements on challenging terrains.

    First, I will briefly review my previous work of modelling animal and robot locomotion on granular terrains such as sand, debris, and gravel, and discuss how legged locomotors could manipulate sand responses through adjustments in morphological parameters or contact strategy. These robot-sand interacting mechanisms have recently enabled development of desert-exploring robot assistants that can use their leg as soil strength sensors, and help human scientists generate erodibility maps by walking around the desert. I will then discuss my recent and on-going work on creating simplified representations for robot locomotion on perturbation-rich environments such as cluttered rubble field or fallen tree trunks, and demonstrate how a multi-legged robot could use different gait patterns to take advantage of obstacle collisions and generate desired motion under repeated disturbances. I will conclude with a vision of how these models and representations are leading to innovative strategies for environment-aided robot locomotion, better understandings of animal gait transition behaviors, and new cognitive workflows of human-robot collaborative explorations.


    Biography: Feifei Qian is an Assistant Professor of Electrical and Computer Engineering at USC. She received her PhD in Electrical Engineering and M.S. in Physics from Georgia Institute of Technology, in 2015 and 2011, respectively. Prior to her appointment at USC, she worked in the GRASP lab at University of Pennsylvania as a postdoctoral fellow. Her expertise is in analyzing and modeling the complex interactions between robots and environments, and developing innovative control and sensing strategies to improve robot mobility on challenging terrains. Her work has been featured in BBC News and R&D Magazine, and was awarded the best student paper of Robotics: Science & Systems.

    Speaker: Daniel Goldman, Georgia Tech

    Talk Title: TBD

    Abstract: Robots will soon move from the factory floor and into our lives (e.g. autonomous cars, package delivery drones, and search-and-rescue devices). However, compared to living systems, robot capabilities in complex environments are limited. I believe the mindset and tools of physics can help facilitate the creation of robust self-propelled autonomous systems. This robophysics approach -“ the systematic search for novel dynamics and principles in robotic systems -- can aid the computer science and engineering approaches which have proven successful in less complex environments. The rapidly decreasing cost of constructing sophisticated robot models with easy access to significant computational power bodes well for such interactions. Drawing from examples in the work of my group and our collaborators, I will discuss how robophysical studies have inspired new physics questions in low dimensional dynamical systems (e.g. creation of analog quantum mechanics and gravity systems) and soft matter physics (e.g. emergent capabilities in ensembles of active particles), have been useful to develop insight for biological locomotion in complex terrain (e.g. control targets via optimizing geometric phase), and have begun to aid engineers in the creation of devices that begin to achieve life-like locomotor abilities on and within complex environments (e.g. semi-soft myriapod robots).

    Talk Title: Cross-Layer Security of Embedded and Cyber-Physical Systems

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: Cyber-physical systems (CPS) are engineered systems that are built from, and depend upon, the seamless integration of computation and physical components [NSF]. Embedded systems comprising of hardware and software systems are the major enabling technology for these cyber-physical systems. Today, CPSs can be found in security-sensitive areas such as aerospace, automotive, energy, healthcare, manufacturing transportation, entertainment, and consumer appliances. Compared to the traditional information processing systems, due to the tight interactions between cyber and physical components in CPSs and closed-loop control from sensing to actuation, new vulnerabilities are emerging from the boundaries between various layers and domains. In this talk, Prof. Al Faruque will discuss how new vulnerabilities are emerging at the intersection of various components and subsystems and their various hardware, software, and physical layers. Several recent examples from various cyber-physical systems will be presented in this talk. To understand these new vulnerabilities a very different set of methodologies and tools are needed. Defenses against these vulnerabilities demand also new hardware/software co-design approaches. The talk will highlight recent developments in this regard. The major goal of this talk will be to highlight various research challenges and the need for novel scientific solutions from the CPS community as well as the EDA, embedded systems, and integrated circuits and systems design communities.

    Biography: Mohammad Al Faruque received his B.Sc. degree in Computer Science and Engineering (CSE) from Bangladesh University of Engineering and Technology (BUET) in 2002, and M.Sc. and Ph.D. degrees in Computer Science from Aachen Technical University and Karlsruhe Institute of Technology, Germany in 2004 and 2009, respectively. He is currently with the University of California Irvine (UCI) as an Associate Professor and Directing the Embedded and Cyber-Physical Systems Lab. He served as an Emulex Career Development Chair from October 2012 till July 2015. Before, he was with Siemens Corporate Research and Technology in Princeton, NJ as a Research Scientist. His current research is focused on the system-level design of embedded and Cyber-Physical-Systems (CPS) with special interest in low-power design, CPS security, data-driven CPS design, etc. He is the author of 2 published books.

    Speaker: Megan Leftwich, George Washington University

    Talk Title: The Hydrodynamics of Sea Lion Swimming

    Abstract: California Sea Lions are highly maneuverable swimmers, capable of generating high thrust and agile turns. Their main propulsive surfaces, the foreflippers, feature multiple degrees of freedom, allowing their use for thrust production (through a downward, sweeping motion referred to as a clap), turning, stability and station holding (underwater hovering). To determine the two-dimensional kinematics of the California sea lion fore flipper during thrust generation, digital, high definition video is obtained using the specimen at the Smithsonian National Zoo in Washington, DC. Single camera videos are analyzed to digitize the flipper during the motions, using 10 points spanning root to tip in each frame. Digitized shapes were then fitted with an empirical function that quantitatively allows for both comparison between different claps and for extracting kinematic data. The resulting function shows a high degree of curvature (with a camber of up to 32%). Analysis of sea lion acceleration from rest shows thrust production in the range of 150-680 N and maximum flipper angular velocity (for rotation about the shoulder joint) as high as 20 rad/s. Analysis of turning maneuvers indicate extreme agility and precision of movement driven by the fore flipper surfaces. This work is being extended to three-dimensions via the addition of a second camera and a sophisticated calibration scheme to create a set of camera-intrinsic properties. Simultaneously, we have developed a robotic sea lion foreflipper to investigate the resulting fluid dynamic structures in a controlled, laboratory setting.

    Speaker: Dr. Qiming Wang, USC

    Talk Title: Harness Natural Wisdom to Design 3D-Printed Bionic Materials

    Abstract: Living creatures are continuous sources of inspiration for designing synthetic materials. However,
    living creatures are typically different from synthetic materials in two aspects: First, living creatures typically
    feature sophisticated microstructures and architectures that are challenging to reproduce in traditional
    engineering practice. Second, living creatures consist of living cells to support their metabolisms, such as
    growth, regeneration, and remodeling, which are typically impossible in traditional synthetic materials. In this
    talk, by harnessing modern additive manufacturing technologies, dynamic chemistry, and/or living organisms,
    we report a series of 3D-printed bionic materials to imitate both architectures and metabolisms of living
    creatures. For example, with the aid of dynamic chemistry, 3D-printed lightweight structures can self-heal
    large-scale impact damages and fractures. With the aid of living bacteria, 3D-printed polymers can self-grow
    into structural composites with pre-designed microstructures. With the aid of living plant cells, 3D-printed
    artificial trees can harness photosynthesis to self-remodel into multifunctional materials.

    Biography: Qiming Wang is an Assistant Professor in the Department of Civil and
    Environmental Engineering of the University of Southern California. Prior to this
    position, he received a Postdoc training at Massachusetts Institute of Technology
    (2014-2015) and earned his Ph.D. degree at Duke University (2014). His research
    interest is centered around additive manufacturing and mechanics of unprecedented
    materials and structures that can potentially address grand engineering challenges,
    including infrastructure, water, environment, robotics, and healthcare. His research
    has been widely reported by prestigious media, such as Science News, Nature News,
    Discovery, Washington Post, NBC News, Wall Street Journal, Physics Today,
    Materials Today, and NASA Tech Briefs. He received a number of academic awards,
    including NSF CAREER (2020), SME Outstanding Young Manufacturing Engineer
    (2020), AFOSR YIP (2018), MRS Graduate Student Award (2014), ACS Arthur K.
    Doolittle Award, Duke Kewaunee Student Achievement Award (2013), Duke Lew Pre-doctoral Fellowship
    (2012), and ASME Best Paper Award (2011). He was elected as the Editor (2018) of ASME Technical
    Committee of Mechanics of Soft Materials and become Secretary in 2019, Vice-chair in 2020, and Chair in

    Talk Title: Improved Real-Time MRI of Speech Production

    Series: Medical Imaging Seminar Series

    Abstract: Human speech is a unique capability that involves complex and rapid movement of vocal tract articulators. Real-time (RT) MRI has provided powerful insight into speech production because of its ability to non-invasively and safely capture the essential dynamic features of the vocal tract during speech. My dissertation is motivated by unmet needs in the field of speech RT-MRI, specifically blurring artifacts and volumetric coverage. In this talk, I will describe two new deblurring methods and a new 3D RT-MRI technique.

    Talk Title: Design Space Exploration of Future Open Rotors

    Abstract: The goal of this paper is to determine whether an open rotor aircraft configuration has the potential to provide fuel-burn benefits relative to a conventional turbofan aircraft, and if so in which regions of the payload range design space adopting an open rotor technology would be most advantageous. A design space exploration focused on the major trends and design drivers is carried out for open rotor aircraft with aft mounted and wing mounted engines, and their performance compared to a turbofan baseline. We consider transport aircraft with ranges between 1000 and 7000 nautical miles and 50 to 400 passengers, and introduce a modeling approach for open rotor engines into a conceptual design and optimization framework. For each range-passenger requirement, aircraft are optimized for minimum fuel burn on an economic range mission. It is found that open rotor configurations are best suited for short range missions with large passenger counts, and that aft mounted open rotors outperfor
    m wing mounted ones. The optimum open rotor engine design sacrifices engine and aerodynamic efficiency in order to limit integration penalties and propulsion system weight.

    Biography: Andrew Dorsey is a PhD student under Professor Uranga. His research focuses on conceptual aircraft design, aircraft optimization, and exploring future aircraft technologies. Andrew works full time in the Advanced Concepts group of Boeing Commercial Airplanes as a conceptual aircraft designer. He is currently on a rotation supporting 737 MAX Return to Service and 777x Entry into Service. Andrew has a B.S. from the University of Michigan, a M.S. from USC, and is a certified flight instructor.

    Talk Title: Genetic Circuits, Cloud Labs, and COVID-19: CPS as Applied to Synthetic Biology

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: Synthetic biology is the process of forward engineering living systems. These systems can be used to produce bio-based materials, agriculture, medicine, and energy. One approach to designing these systems is to employ techniques from the design of embedded electronics. These techniques include abstraction, standards, and formal models. Together these form the foundation of "bio-design automation", where software, robotics, and microfluidic devices combine to create exciting biological systems of the future. In this talk, I will discuss three general topics. The first is how software tools can be created to act as "genetic compilers" that transform high-level specifications into engineered "genetic circuits". The second topic is how these genetic circuits can be automatically communicated to both local and community "cloud labs" where robotics, assembly-line style automation, and formalized protocol descriptions can be employed to safely and efficiently manufacture these systems. Finally, I will conclude with how these two elements have combined in to power the BU Clinical Testing Laboratory where over 5000 COVID-19 tests are performed daily.

    Biography: Douglas Densmore is a Kern Faculty Fellow, a Hariri Institute for Computing and Computational Science and Engineering Faculty Fellow, and Associate Professor in the Department of Electrical and Computer Engineering at Boston University. His research focuses on the development of tools for the specification, design, assembly, and test of synthetic biological systems. His approaches draw upon his experience with embedded system-level design and electronic design automation (EDA). Extracting concepts and methodologies from these fields, he aims to raise the level of abstraction in synthetic biology by employing standardized biological part-based designs which leverage domain-specific languages, constraint-based genetic circuit composition, visual editing environments, microfluidics, and automated DNA assembly. This leads to a new research area he calls "Hardware, Software, Wetware Co-design".

    Talk Title: Pulmonary hypertension assessed using mathematical modeling integrating imaging and time-series data

    Abstract: Cardiovascular disease management involves interpreting imaging data, time-series data, and single-valued markers often measured over several visits. While each data type provides insight into the disease state, these snapshots cannot easily be integrated to provide insight into disease predictions. In this talk, we demonstrate how to interpret the disease state using multiscale mathematical modeling integrating computed tomography (CT) images with blood pressure measurements from right heart categorization. We use these models to characterize patient-specific remodeling in the proximal and distal vasculature. We calculate patient-specific nominal parameter values using morphometric and invasively measured hemodynamic data, use sensitivity analysis to determine what parameters best inform the data, and a Bayesian approach to infer identifiable subject-specific parameters and propagate the uncertainty of pressure and flow predictions to all large vessels. We also validate frequency domain results assessing change in wave-propagation and wave-intensity with the disease. For the micro-vasculature, we conduct a morphometric analysis characterizing changes in the arterial networks' branching structure by extracting skeletonized networks from the micro-CT images and using a custom algorithm to represent the network as a connected graph. We determine subject-specific fractal parameters and analyze how these changes with PH. Our model and data analysis outcomes are combined to understand the link between spatially distributed etiologies and global hemodynamics and shed light on the prospect of combining the model and graph-based morphometric analysis of vascular trees.

    Biography: Dr. Olufsen, Professor, has been associated with the NCSU Mathematics Department since 2001. She got her Ph.D. in Applied Mathematics from Roskilde University, Denmark in 2001, for which she developed a 1D systemic arterial model for use in an Anesthesia Simulator. After graduating, she spent three years at Boston University, working with Nancy Kopell and Ali Nadim. At NCSU her main focus has been on developing patient-specific models for understanding the cardiovascular system and its control. Her recent work has focused on using modeling to understand pulmonary hypertension integrating imaging and time-series data. She has mentored more than 20 graduate students (two who are Assistant Professors at USC) and a large number of undergraduate students. She has published more than 100 manuscripts and organized numerous workshops and conferences including SIAM Life Sciences. She served as a scientific advisor for the Mathematical Biosciences Institute at Ohio State and is currently the director for the NCSU Research for Undergraduates Program.
