Sparsity/Low-rankness-aware proximal methods and their applications to signal processing

Speaker: Seisuke Kyochi, The University of Kitakyushu, Japan

Date: Sep 11

Abstract: Optimization with proximal method has shown to be effective and widely applied in many signal and image processing tasks. In particular, proximal operators for sparse and low-rank modeling have been proposed conventionally, since those characteristics often appear in signal processing. For example, in image recovery problem, the sparsity of gradient is often considered to estimate a latent image, since natural images are basically smooth. For more accurate signal and image processing, more sophisticated structured proximal operators are discussed recently. In this talk, some examples of sparsity/low-rankness-aware proximal methods from the author's group are introduced and shown their effectiveness in experiments.

Collaborative Mobile Charging: From Abstraction to Solution

Date: Sep 12

Speaker: Jie Wu, Temple University

Abstract: Wireless energy charging using mobile vehicles has been a viable research topic recently in the area of wireless networks and mobile computing. This talk gives a short survey of recent research conducted in our research group in the area of collaborative mobile charging. In collaborative mobile charging, multiple mobile chargers work together to accomplish a given set of objectives. These objectives include charging sensors at different frequencies with a minimum number of mobile chargers and reaching the farthest sensor for a given set of mobile chargers, subject to various constraints, including speed and energy limits of mobile chargers. Testbed results are also given on the proposed mobile charging solutions. Through the process of problem formulation, solution construction, and future work extension for problems related to collaborative mobile charging and coverage, we present three principles for good practice in conducting research, that is, select a simple problem, find an elegant solution, and use imagination for extension.

Security and and Privacy for Distributed Optimization and Learning

Speaker: Nitin Vaidya, McDevitt Chair, Department of Computer Science, Georgetown University

Date: Sep 19

Abstract: Consider a network of agents wherein each agent has a private cost function. In the context of distributed machine learning, the private cost function of an agent may represent the “loss function” corresponding to the agent’s local data. The objective here is to identify parameters that minimize the total cost over all the agents. In machine learning for classification, the cost function is designed such that minimizing the cost function should result model parameters that achieve higher accuracy of classification. Similar problems arise in the context of other applications as well, including swarm robotics.
Our work addresses privacy and security of distributed optimization with applications to machine learning. In privacy-preserving machine learning, the goal is to optimize the model parameters correctly while preserving the privacy of each agent’s local data. Privacy-preserving machine learning is becoming important due to the increasing reliance on user-generated data for machine learning. In security, the goal is to identify the model parameters correctly while tolerating adversarial agents that may be supplying incorrect information. When a large number of agents participate in distributed optimization, security compromise of some of the agents becomes increasingly likely. We constructively show that such privacy-preserving and secure algorithms for distributed optimization exist. The talk will provide intuition behind the design and correctness of the algorithms.

Unmasking and Defeating Cache Timing Channels

Speaker: Guru Prasadh Venkataramani, George Washington University

Date: Sep 26

Abstract: Caches present a large attack surface for adversaries to exploit and realize their timing channels. With advances in cache monitoring and protection techniques within individual caches, adversaries may resort to more sophisticated methods such as taking undue advantage of inter-cache hardware mechanisms in order to meet their malicious objectives. It becomes necessary to understand the hardware vulnerabilities and devise mitigation mechanisms to prevent adversaries from exploiting them.
In this talk, I will first briefly describe CC-Hunter our early work that detects cache timing channels using correlation patterns between cache misses. I will then go over some of our recent research that highlights how performance monitoring hardware can be leveraged for better security. Next, we will see how more sophisticated adversaries may target inter-cache hardware mechanisms such as cache coherence protocols.

Learning Representations Using Causal Invariance

Speaker: Léon Bottou, Facebook AI Research

Date: Oct 7

Abstract:Learning algorithms often capture spurious correlations present in the training data distribution instead of addressing the task of interest. Such spurious correlations occur because the data collection process is subject to uncontrolled confounding biases. Suppose however that we have access to multiple datasets exemplifying the same concept but whose distributions exhibit different biases. Can we learn something that is common across all these distributions, while ignoring the spurious ways in which they differ? This can be achieved by projecting the data into a representation space that satisfy a causal invariance criterion. This idea differs in important ways from previous work on statistical robustness or adversarial objectives. Similar to recent work on invariant feature selection, this is about discovering the actual mechanism underlying the data instead of modeling its superficial statistics.


About the Speaker: Léon Bottou received the Diplôme d’Ingénieur de l’École Polytechnique (X84) in 1987, the Magistère de Mathématiques Fondamentales et Appliquées et d’Informatique from École Normale Supérieure in 1988, and a Ph.D. in Computer Science from Université de Paris-Sud in 1991. His research career took him to AT&T Bell Laboratories, AT&T Labs Research, NEC Labs America and Microsoft. He joined Facebook AI Research in 2015. The long-term goal of Léon Bottou’s research is to understand and replicate human-level intelligence. Because this goal requires conceptual advances that cannot be anticipated, Leon’s research has followed many practical and theoretical turns: neural networks applications in the late 1980s, stochastic gradient learning algorithms and statistical properties of learning systems in the early 1990s, computer vision applications with structured outputs in the late 1990s, theory of large scale learning in the 2000s. During the last few years, Léon Bottou’s research aims to clarify the relation between learning and reasoning, with more and more focus on the many aspects of causation (inference, invariance, reasoning, affordance, and intuition.)

Towards Robust Machine Learning in 5G Radio Access Networks

Speaker: Slawomir Stanczak, Heinrich Hertz Institute, Germany

Date: Oct 17

Abstract:Wireless communications poses some fundamental challenges to machine learning (ML). Due to high mobility, wireless links exhibit ephemeral and highly dynamic nature; moreover, the links are corrupted by noise and are in general exposed to interference, while wireless resources (spectrum and energy) are scarce. All this may greatly limit the capacity of wireless networks. Since data (including measurement data) is not available at a single point but distributed among different locations, there is a strong need for distributed ML algorithms that efficiently use the scarce wireless resources in 5G networks. Moreover, the new ML methods need to provide robust results based on small data sets and under latency constraints.

In this talk, we will discuss why ML has the potential for substantially enhancing current radio access networks (RAN) solutions, and we will give an overview of promising techniques and algorithmic approaches for overcoming the above mentioned challenges in 5G networks. We argue in favor of hybrid-driven methods that combine purely data-driven ML approaches with classical model-based methods, while making use of the available expert knowledge. In particular, it is in general necessary to exploit structures in the wireless channel, transmission signals and various functions such as load maps. We will consider both kernel-based methods and deep neural networks. Meeting the latency requirements of 5G networks requires massive parallelization. We'll discuss how to parallelize certain radio access network (RAN) functions to GPU architectures to achieve orders-of-magnitude acceleration.

On representations and fairness: information-theoretic tools for machine learning

Speaker: Flavio du Pin Calmon, Harvard

Date: Oct 24

Abstract: Information theory can shed light on the algorithm-independent limits of learning from data and serve as a design driver for new machine learning algorithms. In this talk, we discuss a set of information-theoretic tools that can be used to (i) help understand fairness and discrimination in machine learning and (ii) characterize data representations learned by complex learning models. On the fairness side, we explore how local perturbations of distributions can help both identify proxy features for discrimination, and how a formulation inspired by information projection can be applied to repair models for bias. On the representation learning side, we explore a theoretical tool called principal inertia components (PICs), which enjoy a long history in the statistics and information theory literature. We use the PICs to scale-up a multivariate statistical tool called correspondence analysis (CA) using neural networks, enabling data dependencies to be visualized and interpreted at a large scale. We illustrate these techniques in both synthetic and real-world datasets, and discuss future research directions.

A Multi-Purpose Vehicle Test Instrument

Speaker: William Rosenbluth, Sophia Y. Wang, Automotive Systems Analysis, Inc.; Peter J. Sullivan, Advanced Analysis Associates, Inc.

Date: Nov 4

Abstract: In the course of many vehicle road and reconstruction tests, the authors found that no single diagnostic or test suite combined their needs for high intuitive graphic visibility while presenting simultaneous data from both CAN networks and analog sensors. This presentation includes five examples of forensic investigation cases requiring such an instrument, and describes how they achieved that new test instrument by using two custom Python scripts to combine the desired parts of existing and cost effective test interfaces to create a new test instrument. The resulting new test instrument implements a test data acquisition and recording package that, in operational road tests, accident reconstructions, and laboratory component tests, acquires and records CAN network and analog sensor data while simultaneously presenting a highly readable and scaled graphical interface to the test operator. The new test instrument was designed to utilize any of several very cost effective USB or PCI CAN and analog interfaces and handles both 11 and 29 bit ID CAN data. It also, in addition to logging raw CAN and scaled parameter data, incorporates a playback feature to review in real time, prior recorded CAN logs from several source formats including Bosch Busmaster®, Intrepid Control Systems®, and Kvaser® as well as its own native format.

Cell-Free Massive MIMO: Make it Competitive!

Speaker: Luca Sanguinetti, University of Pisa

Date: Nov 7

Abstract: Cell-free Massive MIMO is considered as a promising technology for satisfying the increasing number of users and high rate expectations in beyond-5G networks. The key idea is to let many distributed access points (APs) communicate with all users in the network, possibly by using joint coherent signal processing. The aim of this talk is to provide a comprehensive analysis of this technology under different degrees of cooperation among the APs. Particularly, the uplink spectral efficiencies of four different cell-free implementations are analyzed, with spatially correlated fading and arbitrary linear processing. It turns out that it is possible to outperform conventional Cellular Massive MIMO and small cell networks by a wide margin, but only using global or local minimum mean-square error (MMSE) combining. This is in sharp contrast to the existing literature, which advocates for maximum-ratio combining. Also, we show that a centralized implementation with optimal MMSE processing not only maximizes the SE but largely reduces the fronthaul signaling compared to the standard distributed approach. This makes it the preferred way to operate Cell-free Massive MIMO networks. Non-linear decoding is also investigated and shown to bring negligible improvements.

Two trends in post massive MIMO: extra-large scale MIMO and holographic MIMO

Speaker: Elisabeth de Carvalho, Aalborg University, Denmark

Date: Nov 15

Abstract: We describe two current trends in the post massive MIMO research: extra-large scale MIMO and holographic MIMO. Both are extensions of massive MIMO and call for a new generation of base stations equipped with an even larger number of antennas. In extra large scale MIMO, the antenna array at the access point has a very large dimension. In holographic MIMO, the arrays are not necessarily large and are a collection of tiny closely-spaced antenna elements. The prime focus of this presentation is to describe a communication model for holographic MIMO. The proximity of the antenna elements results in mutual coupling. Therefore, it is important to account for the mutual coupling in the communication model but also in the transceiver design. For a single user communication, the optimal transmitter consists of the inversion of the mutual coupling matrix followed by a filter matched to the channel vector. We show that the potential gains of holographic MIMO are superior to conventional arrays with antenna spacing of half a wavelength.

Machine Learning for the Detection of Clinical Deterioration

Speaker: Farah Shamout, NYU Abu Dhabi

Date: Nov 19

Abstract: Clinical deterioration often goes undetected on hospital wards. Assessment of clinical deterioration preceding specific adverse outcomes, such as unplanned ICU admission, cardiac arrest, or mortality, is traditionally done using Early Warning Score (EWS) systems. Those scores consider a limited set of physiological variables, do not account for temporal changes leading to adverse events, are heuristic in nature, or do not generalize well for unseen patient cohorts. Increased access to Electronic Health Records (EHR) motivates the development of more robust and flexible machine learning techniques to improve predictions of clinical deterioration. This talk will focus on the opportunities and challenges of modelling EHR data and the results of the work in which we develop EWS systems using deep learning. It will also present ongoing projects at the MLHR Lab.

AI Seminar Series: Challenges for Deep Reinforcement Learning in Complex Environments

Speaker: Raia Hadsell, DeepMind

Date: Dec 6

Abstract: Deep reinforcement learning has rapidly grown as a research field with far-reaching potential for artificial intelligence. Games and simple physical simulations have been used as the main benchmark domains for many fundamental developments. As the field matures, it is important to develop more sophisticated learning systems with the aim of solving more complex real-world tasks, but problems like catastrophic forgetting remain critical, and important capabilities such as skill composition through curriculum learning remain unsolved. Continual learning is an important challenge for reinforcement learning, because RL agents are trained sequentially, in interactive environments, and are especially vulnerable to the phenomena of catastrophic forgetting and catastrophic interference. This talk will cover some of the challenges that exist for learning from interactions in more complex, constrained, and real-world settings, and some promising new approaches that have emerged.


About the Speakers: Raia Hadsell is the head of Robotics research at DeepMind. Her early research was in the use of Siamese networks for learning neural embeddings, an approach which now commonly used for representation learning. After completing a PhD which featured a self-supervised deep learning vision system for a mobile robot, her research continued at Carnegie Mellon’s Robotics Institute and SRI International, and in early 2014 she joined DeepMind in London to study artificial general intelligence. Dr. Hadsell’s current research focuses on the challenge of continual learning for AI agents and robots, and she has proposed neural approaches such as policy distillation, progressive nets, and elastic weight consolidation to solve the problem of catastrophic forgetting. Dr. Hadsell is on the executive boards of ICLR, WiML, and CoRL, and is a fellow of the European Lab on Learning Systems (ELLIS).
