Hardware Network wireless

Abstract We will discuss Integrated Circuit (IC) security and trust threats and corresponding countermeasures with a focus on wireless ICs. We will present solutions to protect RF transceiver ICs against piracy attempted by malicious System-on-Chip (SoC) integrators, foundries, or end-users via reverse-engineering. We will also present hardware Trojan attacks on RF transceivers aiming at creating a covert channel for stealing sensitive information, i.e., cypher keys. Brief Biography Haralampos-G.

Autonomous system

Abstract Mobile autonomous devices use sophisticated algorithms to automatically navigate diverse physical environments in a safe manner. Guaranteeing system safety while optimizing resource-usage of an autonomous device’s computer is an outstanding challenge. Runtime verification helps provide robustness by monitoring application execution at runtime. These systems operate in dynamic environments, requiring self-aware runtime management to maximize lifetime while enforcing safe execution. Safe execution and lifetime management require consideration of performance and efficiency, two

advanced semiconductors

In this talk, I will first provide an overview of our research on design-for-testability of 3D integrated circuits, silicon lifecycle management, microfluidics, and hardware security, which all involve close industry collaborations. I will next describe in more detail our recent work on design-for-yield that targets manufacturing imperfections for layouts based on emerging carbon nanotube field-effect transistors. Following this, I will present our ongoing work on built-in self-test of monolithic 3D integrated circuits. Finally, I will describe a test and diagnosis technique to characterize fault origins in inter-tier vias and resistive random-access memories for monolithic 3D integration.

Statistics of extremes spatial statistics

This dissertation consists of four major contributions to subasymptotic modeling of multivariate and spatial extremes. The dissertation proposes a multivariate skew-elliptical link model for correlated highly-imbalanced (extreme) binary responses, and shows that the regression coefficients have a closed-form unified skew-elliptical posterior with an elliptical prior.

mean-field games

Models for flows on networks arise in the study of traffic and pedestrian crowds. These models encode congestion effects, the behavior and preferences of agents, such as aversion to crowds and their attempts to minimize travel time. We will present the Wardrop equilibrium model on networks with flow-dependent costs and its connection with stationary mean-field game.

Inference for Longitudinal Data After Adaptive Sampling

Prof. Susan Murphy, Statistics and Computer Science and Radcliffe Alumnae Professor at the Radcliffe Institute, Harvard University

Oct 20, 15:00 - 16:00

Reinforcement Learning

In this work, we proved statistical inference for the common Z-estimator based on adaptively sampled data. Adaptive sampling methods, such as reinforcement learning (RL) and bandit algorithms, are increasingly used for the real-time personalization of interventions in digital applications like mobile health and education. As a result, there is a need to be able to use the resulting adaptively collected user data to address a variety of inferential questions, including questions about time-varying causal effects.
We used Reinforcement Learning; but did it work?

Reinforcement Learning Digital Behavioral Health

Reinforcement Learning provides an attractive suite of online learning methods for personalizing interventions in Digital Behavioral Health. However, after a reinforcement learning algorithm has been run in a clinical study, how do we assess whether personalization occurred? We might find users for whom it appears that the algorithm has indeed learned in which contexts the user is more responsive to a particular intervention. But could this have happened completely by chance? We discuss some first approaches to addressing these questions.
Gradient Estimates for weak solutions of Elliptic PDE's - Colloquium
