Speaker: Elad Alon, CEO, Blue Cheetah Analog Design
Talk Title: Reshaping the A/MS Design Industry with Generators
Series: Integrated Systems
Abstract: The semiconductor industry is in the midst of multiple technological, societal, and market trends - including a resurgence of customized silicon solutions, global capacity shortages, and the end of scaling derived reductions in cost per transistor - that are all aligning to drive surging demand for IC
designs. Accordingly, demand has never been higher for the A/MS components / sub-systems underlying all modern chips, and yet the supply of A/MS design engineers has at best remained flat over the last ~10- 20 years. In this talk I will describe how generator-based design - where we algorithmically codify and
capture expert engineers' methodologies - allow us to "force multiply" the efforts of expert designers and rapidly realize customized, process-portable A/MS designs.
Biography: Dr. Elad Alon is the CEO and co-founder of Blue Cheetah Analog Design, which is leveraging generator-based design methodologies to rapidly deliver tailored A/MS designs to meet our customers' diverse needs. He is an Adjunct Professor at UC Berkeley in the EECS Department, where he was a Full Professor until Jul. 2021. He has served as an advisor or consultant to many semiconductor and electronics companies, including Lion Semiconductor (acquired by Cirrus Logic), Ayar Labs, Intel, Xilinx, Cadence, Wilocity (acquired by Qualcomm), and Cadence. He has been recognized with multiple best-paper (from the ISSCC, VLSI, and CICC conferences)
as well as teaching awards, has led several multi-institutional research programs, and was elevated to the rank of IEEE Fellow in 2020.

EE599: Causal Learning course: Casual Bandits

Speaker: Ali Tajer, Rensselaer Polytechnic Institute
Talk Title: Causal Bandits
Abstract: In this talk, we provide an overview of the causal bandit problems. The purpose of causal bandit settings is to formalize theoretically-principled frameworks for the experimental design when the experiments involve an array of parameters that causally affect one another. The key objective of causal bandits is to leverage causal relationships to design effective experiments judiciously. Designing causal bandit algorithms critically hinges on the extent of information available about the (i) causal structure and (ii) the interventional distributions. Based on the availability of information on each of these two dimensions, there are, broadly, four possible model combinations. The existing literature, for the most part, focuses on settings in which the interventional distributions are known (with or without knowing the causal structure). First, we provide an overview of the existing literature on the existing literature. Secondly, motivated by the fact that acquiring the interventional distributions is often infeasible, we address the following question: is it possible to achieve the optimal regret scaling rates without knowing the interventional distributions? We address this question affirmatively in the case of linear structural equation models when the causal structure is known. We discuss the design and performance of algorithms for the frequentist and Bayesian settings.

Conferences, Lectures, & Seminars
Speaker: Professor Pierluigi Nuzzo, Ming Hsieh Dept of ECE, USC Viterbi School of Engineering
Talk Title: High-Assurance Design Methods for Trustworthy Autonomous Cyber-Physical Systems
Abstract: Correctness and safety assurance is of utmost importance in mission-critical systems for various applications, for example, in avionics, automobiles, robotics, and manufacturing. In these systems, increasingly more sophisticated tasks that were previously allocated to humans are expected to be performed by software, including modern artificial intelligence (AI) methods. One of the biggest challenges to full autonomy is arguably in showing that these AI and autonomous software functions will still satisfy the stringent safety and correctness requirements of mission-critical systems in uncertain or unpredictable environments. In this talk, I will introduce our approach toward enhancing design-time assurance for trustworthy autonomous cyber-physical systems. I will present synthesis methods for correct-by-construction design of optimal control and reinforcement learning policies in uncertain and unknown environments with provable guarantees on the satisfaction of complex missions, expressed by temporal logic specifications. I will then introduce the rich specification formalism of stochastic assume-guarantee contracts for compositional, quantitative requirement analysis and system verification under uncertainty. Finally, I will discuss how stochastic contracts can provide the semantic foundation for the automated construction of assurance cases, structured arguments about system dependability, which can accelerate system certification and help transition from a process-driven to a property-driven certification approach.

Speaker: Abhishek Cauligi, Jet Propulsion Laboratory
Talk Title: Enabling Long Range Autonomy for the Next Generation of Spacecraft Robotic Missions
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Surface rovers have a rich history of use for planetary body exploration, but current rover missions are limited to low operational speeds and require significant ground-in-the-loop management and teleoperation to compute safe paths for the rovers to follow. However, the next generation of proposed planetary surface rover missions require significantly faster operating speeds in order to accomplish the mission tasks and objectives, thereby making autonomy a key enabling technology for such missions. This talk will discuss the challenges ahead in developing, validating, and safely deploying autonomy algorithms for the next generation of spacecraft robotic missions. The first half of this talk will focus on the autonomy architecture for NASA's Cooperative Autonomous Distributed Robotic Explorers (CADRE) mission, a technology demonstration mission that will deliver a team of autonomous rovers to the Moon's Reiner Gamma region in 2024. The latter half of the talk will focus on how recent advances in bridging data-driven approaches with nonlinear optimization can allow for embedding sophisticated planning and decision making capabilities on resource-constrained autonomous systems.

Talk Title: Recent Advances in Millimeter-wave Silicon Photonics Circuits for Wireless Communications
Series: Integrated Systems
Abstract: Nowadays, continuously growing wireless traffic shapes the progress in the wireless communication systems. Therefore, next generation of wireless communication systems are actively
investigated to accommodate expanding data traffic of the future. As one of the promising candidates, silicon photonics devices and circuits are able to improve the performance of the future wireless system.
In this seminar, potential hybrid-integrated mm-wave silicon photonics receivers for future wireless communication systems are explored. The proposed mm-wave silicon photonics reconfigurable receiver front-end can be programmed as either a mm-wave band-pass filter (BPF) for channel selection or a mmwave notch filter for jammer rejection in adjacent and alternate channels within 20-43.5 GHz frequency range. This photonically-assisted mm-wave receiver is optimized for minimum noise figure (NF), maximum linearity or third-order input intercept point (IIP3) and maximum signal to noise ratio (SNR) by optical modulator bias control and optical amplification. Meanwhile, silicon photonics devices are
vulnerable to process and temperature variations. As a result, they require manual calibration, which is expensive, time consuming, and prone to human errors. Therefore, precise automatic calibration solutions with modified monitor-based silicon photonic filter structures are demonstrated and employed in the mmwave silicon photonics receiver. Also, thermal crosstalk effect in the photonic devices is investigated, and substrate thinning is proposed to suppress this effect and reduce calibration time to less than half. The proposed monitor-based tuning method compensates fabrication variations and thermal crosstalk by controlling micro-heaters as tuning elements individually using electrical monitors. This approach
successfully demonstrates calibration and dynamic tuning of silicon photonics filters in the mm-wave receiver from severely degraded initial magnitude response to a well-defined magnitude response.

Talk Title: Space-time wave packets: A new frontier for structured light
Series: Photonics Seminar Series
Abstract: Exercising control over the spatial degrees of freedom of the optical field has continued to yield breakthroughs over the past few decades, ranging from the discovery of Bessel beams and beams endowed with orbital angular momentum, to optical tweezers and traps, and the manipulation of the field in multimode optical fibers. Separately, but in parallel with these efforts, ultrafast pulse shaping has revolutionized our control over the temporal degree of freedom of the optical field. The spatial and temporal realms in optics have led for the most part independent lives with few examples of creative intersections. In this talk I show that precise, joint sculpting of the spatial and temporal degrees of freedom of optical fields - rather than modulating each separately - yields a new class of pulsed beams that I call 'space-time' (ST) wave packets. Surprising and useful optical behaviors are exhibited by ST wave packets when freely propagating or when interacting with photonic devices, leading to a new frontier for the study of structured light. I will share our recent experimental and theoretical results from this rapidly emerging topic and sketch potential applications that could benefit from ST wave packets.

Talk Title: Spin dynamics in antiferromagnets and its applications
Series: Nano Science & Technology
Abstract: Antiferromagnets (AFM) materials have ordered spin moments that alternate between individual atomic sites, which gives them a vanishing macroscopic magnetic signature and picosecond intrinsic timescale. Traditionally, AFM materials have played a secondary role to ferromagnets, which are used as active elements in commercial spintronic devices like magnetic sensors and non-volatile magnetic memory. However, it was recently suggested that spin transfer torque could in principle be used to manipulate the magnetic order in AFMs, leading to either stable AFM order precessions for their use as high-frequency oscillators, or switching of the AFM order for their use as magnetic memories.
My presentation will focus on the physics and modeling of electrically driven spin dynamics in thin films of two unique AFMs: Cr2O3, a single-phase magnetoelectric material that can be manipulated solely with electric fields and the Weyl semi-metal Mn3Sn in which spin torque can induce chiral spin rotations. Cr2O3-based ferromagnet-free random access memory has been experimentally demonstrated, while in the case of Mn3Sn, spin torque driven dynamics were found to induce chiral oscillations, from the megahertz to the terahertz frequency range. These materials can overcome the central challenge of manipulating and reading the AFM's order parameter via microelectronics compatible circuitry, thus allowing us to develop antiferromagnetic spintronics along a similar route as ferromagnetic spintronics.
I will discuss my group's recent work in developing new analytic models and numerical techniques to handle the complex domain dynamics across many length scales and time scales in AFM structures. I will use these models to explain recent experimental findings and bridge the gap between physics and applications development. I will conclude my talk by summarizing the limits, challenges, and opportunities of AFM spintronics for future technologies such as high-density, secure nonvolatile memory, compact narrowband terahertz sources, and spike generators.

Talk Title: Runtime Assurance for Safe Autonomy from Fast, In-the-Loop Reachability
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: In this talk, we show how efficient reachability methods enable runtime assurance (RTA) for safe autonomy. We focus on interconnected and/or high dimensional systems and we leverage reachability techniques enabled by mixed monotone systems theory. Mixed monotonicity decomposes a dynamical system's vector field into cooperative and competitive elements, resulting in a larger dimensional monotone system for which powerful results from monotone systems theory for, e.g., reachability and invariance are applicable. Notably, these methods offer two key properties: they enable reachable set over-approximations that can be computed very fast for, e.g., inclusion at runtime in feedback controllers, and they scale to high dimensional systems such as neural networks. We demonstrate how both of these appealing features enable RTA mechanisms with provable guarantees for learning-enabled control systems.
