SUMMARY:MEAM Seminar: "Open Access Benchmark Datasets and Metamodels for Problems in Mechanics"
DESCRIPTION:Metamodels\, or models of models\, map defined model inputs to defined model outputs. When metamodels are constructed to be computationally cheap\, they are an invaluable tool for applications ranging from topology optimization\, to uncertainty quantification\, to real-time prediction\, to multi-scale simulation. In particular\, for heterogeneous materials\, metamodels are useful for exploring the influence of the (potentially massive) heterogeneous material property parameter space. By nature\, a given metamodel will be tailored to a specific dataset. However\, the most pragmatic metamodel type and structure will often be general to larger classes of problems. At present\, the most pragmatic metamodel selection for dealing with mechanical data — specifically simulations of heterogenous materials — has not been thoroughly explored. In this work\, we draw inspiration from the benchmark datasets available to the computer vision research community. These benchmark datasets have both made it feasible to compare different methods for solving the same problem\, and inspired new directions for method development. In response\, we introduce benchmark datasets for engineering mechanics problems (for example\, the Mechanical MNIST Collection https://open.bu.edu/handle/2144/39371 [1\,2\,3]). Then\, we show some example problems that we are exploring with these datasets such as our methodology for constructing metamodels for predicting full field quantities of interest (e.g.\, full field displacements\, stress\, strain\, or damage variable)\, and for leveraging information from multiple simulation fidelities\, and for predicting out of distribution behavior. Looking forward\, we anticipate that disseminating both these benchmark datasets and our computational methods will enable the broader community of researchers to develop improved techniques for understanding the behavior of spatially heterogeneous materials. We also hope to inspire others to use our datasets for educational and research purposes\, and to disseminate datasets and metamodels specific to their own areas of interest (https://elejeune11.github.io/). \n[1] Lejeune\, E.

SUMMARY:CIS Seminar: "Live Programming and Programming by Example: Better Together"
DESCRIPTION:Live programming is a paradigm in which values from program execution are shown to the programmer through continual feedback. Programming by example is a paradigm in which code is synthesized from example values showing a desired behavior. This talk presents some of our recent research that combines these two paradigms in beneficial ways. I will walk through our ideas\, explain our contributions\, discuss what we learned and finally provide thoughts for the future.

SUMMARY:ASSET Seminar: Explainable AI via Semantic Information Pursuit (René Vidal\, Johns Hopkins University)
DESCRIPTION:Presentation Abstract:  \nThere is a significant interest in developing ML algorithms whose final predictions can be explained in domain-specific terms that are understandable to a human. Providing such an “explanation” can be crucial for the adoption of ML algorithms in risk-sensitive domains such as healthcare. This has motivated a number of approaches that seek to provide explanations for existing ML algorithms in a post-hoc manner. However\, many of these approaches have been widely criticized for a variety of reasons and no clear methodology exists for developing ML algorithms whose predictions are readily understandable by humans. To address this challenge\, we develop a method for constructing high performance ML algorithms that are “explainable by design”. Namely\, our method makes its prediction by asking a sequence of domain- and task-specific yes/no queries about the data (akin to the game “20 questions”)\, each having a clear interpretation to the end-user. We then minimize the expected number of queries needed for accurate prediction on any given input. This allows for human interpretable understanding of the prediction process by construction\, as the questions which form the basis for the prediction are specified by the user as interpretable concepts about the data. Experiments on vision and NLP tasks demonstrate the efficacy of our approach and its superiority over post-hoc explanations. Joint work with Aditya Chattopadhyay\, Stewart Slocum\, Benjamin Haeffele and Donald Geman. \nSpeaker Bio: \nDr. René Vidal is the Herschel Seder Professor of Biomedical Engineering\, and the Director of the Mathematical Institute for Data Science (MINDS)\, the NSF-Simons Collaboration on the Mathematical Foundations of Deep Learning and the NSF TRIPODS Institute on the Foundations of Graph and Deep Learning at Johns Hopkins University.

SUMMARY:Fall 2022 GRASP SFI: Zhongyu Li\, University of California Berkeley\, “Can We Bridge Model-based Control and Model-free RL on Legged Robots?”
DESCRIPTION:*This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom. \nIn this talk\, I will provide a brief introduction about our recent progress in applying optimal control and deep reinforcement learning (RL) on legged robots in the real world. I will then dive into our recent work to bridge model-based safety-critical control and model-free RL on a highly nonlinear and complex system\, such as a bipedal robot Cassie. Bridging model-based safety and model-free RL for dynamic robots is appealing since model-based methods are able to provide formal safety guarantees\, while RL-based methods are able to exploit the robot agility by learning from the full-order system dynamics. I will discuss a new method to combine them by explicitly finding a low-dimensional model of the system controlled by a RL policy and applying stability and safety guarantees on that simple model. \n

SUMMARY:MSE Seminar: "Materials Growth and Discovery for Magnetic and Quantum Applications"
DESCRIPTION:For functional materials that are in a nascent stage\, such as the antiferromagnetic spintronics\, quantum information storage\, and new semiconducting compounds\, it is not clear what will be the high-performance materials of tomorrow. There is a pressing need to examine the complex properties of these emerging materials\, and growing single crystals is a crucial step toward investigating their properties in detail. I will explain why measuring transport\, optical\, and magnetic properties are important in these systems\, and how to determine their anisotropy. Due to the required millimeter dimensions\, they must be grown from solutions\, fluxes\, or vapors. This process is often hard to observe\, and highly kinetically dependent\, so in situ techniques can be especially valuable to understand how to grow larger or better crystals\, how to choose phases more precisely\, and how to discover entirely new materials. With a clearer view of how materials form\, we can critically evaluate computational predictions (ab initio or machine-learned methods) and explore novel reactions to target new phases.

SUMMARY:Theory Seminar- Recent Developments in Combinatorial Auctions\, Matt Weinberg (Princeton University)
DESCRIPTION:Abstract: In a combinatorial auction there are m items\, and each of n players has a valuation function v_i which maps sets of items to non-negative reals. A designer wishes to partition the items into S_1\,…\,S_n to maximize the welfare (\sum_i v_i(S_i) )\, perhaps assuming that all v_i lie in some class V (such as submodular\, subadditive\, etc.). \nWithin Algorithmic Game Theory\, this problem serves as a lens through which to examine the interplay between computation and incentives. For example: is it the case that whenever a poly-time/poly-communication algorithm for honest players can achieve an approximation guarantee of c when all valuations lie in V\, a poly-time/poly-communication truthful mechanism for strategic players can achieve an approximation guarantee of c when all valuations lie in V as well? \nIn this talk\, I’ll give a brief history\, then survey three recent results on this topic which: \n– provide the first separation between achievable guarantees of poly-communication algorithms and poly-communication truthful mechanisms for any V (joint works with Mark Braverman and Jieming Mao\, and with Sepehr Assadi\, Hrishikesh Khandeparkar\, and Raghuvansh Saxena). \n– revisit existing separations between poly-time algorithms and poly-time truthful mechanisms via a new solution concept “Implementation in Advised Strategies” (joint work with Linda Cai and Clayton Thomas). \n– resolve the communication complexity of combinatorial auctions for two subadditive players (joint work with Tomer Ezra\, Michal Feldman\, Eric Neyman\, and Inbal Talgam-Cohen\, time-permitting).

SUMMARY:MEAM Seminar: "Manually-Operated\, Slider Cassette for Multiplexed Molecular Detection at the Point of Care"
DESCRIPTION:Effective control of epidemics\, individualized medicine\, and new drugs with virologic response-dependent dose and timing require\, among other things\, simple\, inexpensive\, multiplexed molecular detection platforms suitable for point of care and for home use. Conventional molecular detection methods such as PCR tests\, require bulky and expensive equipment\, trained personnel\, and specialized laboratories\, limiting their use to centralized facilities. \nIn this talk\, I will describe our 3D-printed slider cassette for the co-detection of the human immunodeficiency virus (HIV)\, hepatitis B virus (HBV)\, and hepatitis C virus (HCV) – three blood-borne pathogens that co-infect numerous people worldwide with severe personal and public health consequences. Novel features of our cassette include the integration of sample processing; nucleic acid isolation and concentration\, isothermal amplification\, minimally instrumented and instrument free detection; refrigeration-free storage of reagents; the ability to co-detect multiple pathogens\, and minimal requirements from the user. Furthermore\, the various processes in our devices can be incubated electricity-free with heat provided by an exothermic reaction and temperature control with phase change materials.

SUMMARY:ESE Ph.D. Thesis Defense: "Lattice Theory in Multi-Agent Systems"
DESCRIPTION:Ordered sets model signals such as binary relations\, concepts\, partitions\, rankings\, matchings\, events\, as well as other taxa of information\, temporal\, hierarchical\, relational\, or\, in general\, logical in nature. We argue that (order-) lattice-based (networked) multi-agent systems constitute a broad class of systems in which data fusion\, consensus\, synchronization\, and other collaborative tasks are described with lattices and Galois connections (maps between lattices that preserve structure). Mathematically speaking\, these systems are network sheaves. Motivated by analogous vector diffusion and consensus algorithms\, we initiate a discrete Hodge theory with the Tarski Laplacian\, a diffusion operator—analogous to the graph Laplacian and the graph connection Laplacian—acting on assignments of lattice-valued data to the nodes of a network. The Hodge-Tarski theorem (Main Theorem) relates the fixed point theory of the Tarski Laplacian to the global sections (consistent signals\, equilibria\, if you will) of the sheaf. We present novel applications in signal processing and multi-modal semantics where we design a consensus algorithm on statements such as “I know that she knows that he doesn’t know that I’m defending my thesis.”

SUMMARY:MEAM Seminar: "Development of Astronomical Instrumentation to Study the Birth and Evolution of the Universe"
DESCRIPTION:The study of the early universe requires deep high-resolution maps of the sky at millimeter and submillimeter. This requires the development of state-of-the-art cryogenic receivers and custom built telescopes. These instruments operate in extreme locations including from NASA launched high-altitude balloons over Antarctica and high (5\,200m/17\,000ft) mountain tops in Northern Chile adding a level of planning and complexity beyond what is normally required for astronomical observations. I will discuss the science goals of these instruments and how we develop instruments at Penn to meet these goals.

SUMMARY:MEAM Ph.D. Thesis Defense: "Surface and Interface Engineering in Manipulation and Fabrication of Colloid-Based Sub-Microporous Hierarchical Materials and Their Applications"
DESCRIPTION:Nanolattices exhibit attractive mechanical\, energy conversion\, and optical properties\, but it is challenging to fabricate nanolattices in large scale while maintaining the dense hierarchical nanometer features that enable their properties. Current advanced fabrication methods\, like 3D printing or self-assembly\, are significantly limited by their scalability or the cracking problem in the assembled templates. This work focuses on self-assembly of metallic inverse opals\, a particular type of nanolattices\, to overcome these limitations via developing a theoretical model for understanding the cracking problem and a crack-free self-assembly method to scale-up the fabrication and to characterize and explore applications of metallic inverse opals. \nThe developed model incorporates film yielding\, particle order\, and interfacial friction to explain several experimental observations and helps solving the cracking problem. It is found that the key to solving the cracking problem is to manipulate the surface and interface properties of particles and substrates. The developed crack-free self-assembly approach results in centimeter-scale nickel inverse opals with much larger crack-free area than prior self-assembled and much more unit cells than 3D-printed nanolattices\, demonstrating a tensile strength of 260 MPa. It is also found that drop-casting can achieve fast\, high-quality\, and large-scale self-assembly via pre-assembly in highly concentrated micro/nanoparticle suspension. \nBased on these development and findings\, two applications of metallic inverse opals have been demonstrated\, including a mechanochromic bending sensor and a magnetic sorting chip for capturing disease-related extracellular vesicles. The developed sensor is wireless and power-free\, can utilize full visible spectrum\, and has a 10X higher strain sensitivity than other mechanochromic sensors. The fabricated sorting chip achieves >109 nanoscale magnetophoretic sorting devices in a postage-stamp-sized lattice with >70x magnetic traps and >20x improved enrichment for magnetic nanoparticles versus previous studies. \nThe understanding of cracking in particle templates\, the developed self-assembly methods\, and the application demonstrations reported in this work may advance the fabrication and applications of high-strength multifunctional porous materials\, providing fundamental insights into the design\, synthesis\, and control of complex hierarchical materials that employ colloid self-assembly.

SUMMARY:ASSET Seminar: Equivariance in Deep Learning\, Kostas Daniilidis (University of Pennsylvania)
DESCRIPTION:ABSTRACT\nTraditional convolutional networks exhibit unprecedented robustness to intraclass nuisances when trained on big data. Generalization with respect to geometric transformations has been achieved via expensive data augmentation. It has been shown recently that data augmentation can be avoided if networks are structured such that feature representations are transformed the same way as the input\, a desirable property called equivariance. In this talk\, we show how equivariance can be realized via group convolutions\, how to deal with vector and tensor fields\, and how we achieve equivariance in transformers. We present results on 3D shape classification and scene reconstruction based on learning only objects but not scenes. \nBIO \nKostas Daniilidis has been faculty at the University of Pennsylvania since 1998.  He is an IEEE Fellow. He was the director of the GRASP laboratory from 2008 to 2013. He obtained his Ph.D. in Computer Science from the University of Karlsruhe (now KIT) in 1992. He is a co-recipient of the Best Conference Paper Award at ICRA 2017. Kostas’ main interest today is in geometric deep learning\, event-based neuromorphic vision\, and their applications in vision-based manipulation and navigation.

SUMMARY:Fall 2022 GRASP SFI: Millind Tambe\, Harvard University\, "Results from deployments for public health and conservation"
DESCRIPTION:*This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom here… \n  \nABSTRACT\nWith the maturing of AI and multiagent systems research\, we have a tremendous opportunity to direct these advances towards addressing complex societal problems. I  will focus on  domains of public health and conservation\,  and address one key cross-cutting challenge: how to effectively deploy our limited intervention resources in these problem domains. I will present results from work around the globe in using AI for challenges in public health such as Maternal and Child care interventions\, HIV prevention\, and in conservation such as  endangered wildlife protection. Achieving social impact in these domains often requires methodological advances. To that end\, I will highlight key research advances in multiagent reasoning and learning\, in particular in\, restless multiarmed bandits\, influence maximization in social networks\, computational game theory and decision-focused learning. In pushing this research agenda\, our ultimate goal is to facilitate local communities and non-profits to directly benefit from advances in AI tools and techniques.

SUMMARY:Fall 2022 GRASP Seminar: Guillermo Gallego\, Technical University Berlin\, "Stereo depth and optical flow estimation via contrast maximization of event camera data”
DESCRIPTION:*This is a HYBRID Event with in-person attendance in Levine 307 and virtual attendance via Zoom. \nABSTRACT\nEvent cameras are novel vision sensors that mimic functions from the human retina and offer potential advantages over traditional cameras (low latency\, high speed\, high dynamic range\, etc.). They acquire visual information in the form of pixel-wise brightness changes\, called events. This talk presents event processing approaches for motion estimation in computer vision and robotics applications. In particular\, we will discuss recent advances by the Robotic Interactive Perception Lab at TU Berlin in extending the contrast maximization framework to stereo depth and optical flow estimation while avoiding its Achilles’ heel: event collapse.

SUMMARY:MEAM Ph.D. Thesis Defense: "Room-temperature Electrochemical Healing of Structural Metals"
DESCRIPTION:For over 6\,000 years\, repairing high-strength metallic materials has required high temperatures and large energy inputs. Likewise\, recent innovations in self-healing and repairable metals have remained limited by the need for heating\, the small size of repairable cracks\, and the low strength and constrained chemical composition of healed metals. While welding remains the most widely used approach to repair metals\, the increasing ubiquity of digital manufacturing and “unweldable” alloys call for radically different approaches. This thesis pioneers a new approach for repairing structural metals at room-temperature\, termed “electrochemical healing”. First\, by mimicking the transport-mediated healing of bone\, selective nickel electrodeposition enables rapid\, effective\, low-energy\, and room-temperature healing of a cellular metal. A polymer coating restricts electrodeposition only at fracture or high stress sites\, and a statistical method quantifies and predicts the probability of a target recovery of tensile strength based on energy input. This thesis extends room-temperature healing to low-carbon steel\, a widely used structural metal\, by elucidating how ion transport and electrolyte chemistry influence growth morphology and strength in fractured steel wires repaired with nickel electrodeposition. Pulsed electroplating and electrolyte chemistry selection improve nickel adhesion and enable fully fractured steel wires to recover up to 69% of their pristine strength. Finally\, this thesis presents a framework for effective room temperature electrochemical healing based on a quantitative model that links geometric\, mechanical\, and electrochemical parameters to the recovery of tensile strength in repaired metals. This framework enables full recovery of tensile strength in a variety of structural metals\, including “unweldable” alloys and a 3D-printed difficult-to-weld funicular shellular structure\, as well as over 100% recovery of toughness in an aluminum alloy. The model reveals scaling relationships for the energetic\, financial\, and time costs of repairing metals that facilitate the practical adoption of electrochemical healing. Room-temperature electrochemical healing could open exciting possibilities for the scalable\, autonomous\, repeatable\, and prophylactic repair of metals in structures and robots\, enable cellular materials that respond to environmental stimulus with growth and morphogenesis\, and advance the life cycle sustainability of structural metals.

SUMMARY:MEAM Seminar: "Harnessing Physical Intelligence for High-Performance Soft Robots"
DESCRIPTION:Different from neuron-based computational intelligence through the brain\, physical intelligence leverages structural designs and smart materials to physically encode sensing\, actuation\, control\, adaption\, and decision-making into the body of an agent. The stimuli-responsive body materials can enable autonomous sensory\, actuation\, powering\, and other physical intelligence functions. The structural designs of soft body can simplify the required actuation for deformation and motion\, as well as enable real-time feedback control-free locomotion and self-adaption. \nIn this talk\, I will discuss our recent work in embodying mechanical intelligence of structural designs and/or materials intelligence of soft active materials in soft robotics\, for achieving delicacy in manipulation\, high speed and high efficiency in locomotion\, and autonomy and intelligence. First\, I will talk about utilizing the ancient paper cutting art of kirigami for programming 3D curved shape shifting via geometric mechanics guided design\, as well as its application in nondestructive and delicate grasping. Then\, I will discuss how to leverage bistability and multistability for achieving high-speed and high-efficient terrestrial and aqueous soft robots. Finally\, I will discuss examples of integrating structural designs with soft active materials for achieving autonomy and intelligence in soft robots.

SUMMARY:ESE/CIS Joint Seminar: "Future Heterogeneous Systems Need More First-Class Citizens"
DESCRIPTION:In recent years\, system designers have increasingly been turning to heterogeneous systems to improve performance and energy efficiency.  Specialized accelerators are frequently used to improve the efficiency of computations that run inefficiently on conventional\, general-purpose processors. As a result\, systems ranging from smartphones to datacenters\, hyperscalers\, and supercomputers are increasingly using large numbers of accelerators (including GPUs) while providing better efficiency than CPU-based solutions.  In particular\, GPUs are widely used in these systems due to their combination of programmability and efficiency.  Traditionally\, GPUs are throughput-oriented\, focused on data parallelism\, and assume synchronization happens at a coarse granularity.  However\, programmers have begun using these systems for a wider variety of applications which exhibit different characteristics\, including latency-sensitivity\, mixes of both task and data parallelism\, and fine-grained synchronization.  Thus\, future heterogeneous systems must evolve and make deadline-aware scheduling\, more intelligent data movement\, efficient fine-grained synchronization\, and effective power management first-order design constraints.  In the first part of this talk\, I will discuss our efforts to apply hardware-software co-design to help future heterogeneous systems overcome these challenges and improve performance\, energy efficiency\, and scalability.  Then\, in the second part I will discuss how the on-going transition to chiplet-based heterogeneous systems exacerbates these challenges and my vision for extending our work to address these challenges in chiplet-based heterogeneous systems by rethinking the control plane.

SUMMARY:Penn Engineering 2021-22 Heilmeier Award Lecture: Ritesh Agarwal
DESCRIPTION:“Utilizing Quantum Geometry and Topology for Enabling Integrated Chiral Photonics”\nClassical and quantum computing devices need to ferry vast amounts of data\, and optical interconnects provide a promising approach allowing faster speeds and larger bandwidths. Critical interconnect components are light sources\, waveguides and detectors. Currently\, the information is encoded in intensity and frequency but other degrees of freedom (DOFs) such as photon spin and spatial orbital angular momentum modes (OAM) should be utilized to enhance the capacity of optical links. Therefore\, new photonic materials and devices that can produce\, transmit and detect light with complex polarization and spatial modes are needed. This is non-trivial as most materials are insensitive to chiral light. In this talk\, Dr. Agarwal will discuss recent developments towards the development of on-chip lasers\, waveguides and photodetectors that are sensitive to photon spin and OAM modes. By protecting or breaking certain symmetries and utilizing the quantum geometry of the engineered system\, new devices will be discussed that can enable the development of integrated chiral photonic systems. \nRead the full award announcement here.

SUMMARY:ASSET Seminar: Learning with Small Data\, Pratik Chaudhari (University of Pennsylvania)
DESCRIPTION:Abstract:\nThe relevant limit for machine learning is not N → infinity but instead N → 0. The human visual system is proof that it is possible to learn categories with extremely few samples. This talk will discuss steps towards building such systems and it is structured in three parts. The first part will discuss algorithms to adapt representations of deep networks to new categories with few labeled data. The second part will discuss when such adaptation works well and when it does not. It will develop a method to compute the optimal distance between two learning tasks and algorithmic tools to learn tasks that are far away from each other. The third part will discuss how make the optimal use of unlabeled data to learn a task. \nThis talk will discuss results from the following papers.\n1.

SUMMARY:Fall 2022 GRASP SFI: Ross Hatton\, Oregon State University\, "Snakes & Spiders\, Robots & Geometry"
DESCRIPTION:*This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom here… \nABSTRACT\nLocomotion and perception are a common thread between robotics and biology. Understanding these phenomena at a mechanical level involves nonlinear dynamics and the coordination of many degrees of freedom. In this talk\, I will discuss geometric approaches to organizing this information in two problem domains: Undulatory locomotion of snakes and swimmers\, and vibration propagation in spider webs. \nIn the first section\, I will discuss how differential geometry and Lie group theory provide insight into the locomotion of undulating systems through a vocabulary of lengths\, areas\, and curvatures. In particular\, a tool called the *Lie bracket* combines these geometric concepts to describe the effects of cyclic changes in the locomotor’s shape\, such as the gaits used by swimming or crawling systems. Building on these results\, I will demonstrate that the geometric techniques are useful beyond the “clean” ideal systems on which they have traditionally been developed\, and can provide insight into the motion of systems with considerably more complex dynamics\, such as locomotors in granular media. \nIn the second section\, I will turn my attention to vibration propagation through spiders’ webs. Due to poor eyesight\, many spiders rely on web vibrations for situational awareness. Web-borne vibrations are used to determine the location of prey\, predators\, and potential mates. The influence of web geometry and composition on web vibrations is important for understanding spider’s behavior and ecology. Past studies on web vibrations have experimentally measured the frequency response of web geometries by removing threads from existing webs. We have constructed physical artificial webs and computer models to better understand the effect of web structure on vibration transmission. These models provide insight into the propagation of vibrations through the webs\, the frequency response of the bare web\, and the influence of the spider’s mass and stiffness on the vibration transmission patterns.
