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

Speaker: Seisuke Kyochi, The University of Kitakyushu, Japan

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

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

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.

Manned and Autonomous Vehicle Dynamics and Design: Towards Convergence and Transdisciplinary Technologies

Speaker: Vladimir Vantsevich, University of Alabama at Birmingham

Abstract: This seminar discusses four emerging research directions in manned and autonomous ground vehicle dynamics and vehicle design that provide necessary conditions for creating vehicle transformative technologies:
1. Vehicle operational properties and vehicle system design
2. Specific features of autonomous vehicle dynamics and design
3. Coupled and interactive dynamics of vehicle systems
4. Vehicle mechatronics and intelligent physical systems
5. Open architecture system design
6. Agile tire and vehicle dynamics
Wheel-power-distribution optimization and control ensured by mechanical and mechatronic driveline systems and by hybrid and electrical virtual/distributed driveline systems is presented as a key foundation of the above-listed research directions.
Several research and engineering projects accomplished for industry and government within the four research avenues are presented to illustrate the effectiveness of the proposed analytical methods and engineered systems, including a new hybrid-electric power transmitting unit, a new wheel rotational kinematics sensor, various limited slip and controllable differentials, and wheel power management control algorithms for fully electric vehicles. The seminar presents and discusses results on fundamental improvements of terrain mobility, vehicle energy efficiency, maneuver, stability of motion and safety of terrain vehicles.

Unmasking and Defeating Cache Timing Channels

Speaker: Guru Prasadh Venkataramani, George Washington University

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.
