Transmit Solutions for MIMO Wiretap Channels using Alternating Optimization
TL;DR: This paper considers transmit optimization in multi-input multi-output (MIMO) wiretap channels, wherein they aim at maximizing the secrecy capacity or rate of an MIMO channel overheard by one or multiple eavesdroppers, and proposes an alternating optimization (AO) approach to tackle these secrecy optimization problems.
Journal ArticleDOI
Optimal Pricing to Manage Electric Vehicles in Coupled Power and Transportation Networks
TL;DR: A scheme in which independent power and transportation system operators can collaborate to manage each network towards a socially optimum operating point while keeping the operational data of each system private is proposed.

A Two-Timescale Framework for Bilevel Optimization: Complexity Analysis and Application to Actor-Critic
TL;DR: These are the first convergence rate results for using nonlinear TTSA algorithms on the concerned class of bilevel optimization problems and it is shown that a two-timescale actor-critic proximal policy optimization algorithm can be viewed as a special case of the framework.
Proceedings Article
Multi-Agent Reinforcement Learning via Double Averaging Primal-Dual Optimization
TL;DR: In this paper, the authors proposed a double averaging scheme, where each agent iteratively performs averaging over both space and time to incorporate neighboring gradient information and local reward information, and proved that the proposed algorithm converges to the optimal solution at a global geometric rate.
Journal ArticleDOI
Optimal Pricing to Manage Electric Vehicles in Coupled Power and Transportation Networks
TL;DR: In this article, the authors study the system-level effects of the introduction of large populations of electric vehicles on the power and transportation networks, and show that a lack of attention to interdependencies between the two infrastructures can have adverse operational effects.
