Support Recovery of Periodic Mixtures with Nested Periodic Dictionaries
Pouria Saidi, George K. Atia
Periodic signals composed of periodic mixtures admit sparse representations in nested periodic dictionaries (NPDs). Therefore, their underlying hidden periods can be estimated by r…
BOSS: Bidirectional One-Shot Synthesis of Adversarial Examples
Ismail R. Alkhouri, Alvaro Velasquez, George K. Atia
The design of additive imperceptible perturbations to the inputs of deep classifiers to maximize their misclassification rates is a central focus of adversarial machine learning. A…
Inferring Probabilistic Reward Machines from Non-Markovian Reward Processes for Reinforcement Learning
Taylor Dohmen, Noah Topper, George Atia +3
The success of reinforcement learning in typical settings is predicated on Markovian assumptions on the reward signal by which an agent learns optimal policies. In recent years, th…
Coarse to Fine Two-Stage Approach to Robust Tensor Completion of Visual Data
Yicong He, George K. Atia
Tensor completion is the problem of estimating the missing values of high-order data from partially observed entries. Data corruption due to prevailing outliers poses major challen…
Controller Synthesis for Omega-Regular and Steady-State Specifications
Alvaro Velasquez, Ismail Alkhouri, Andre Beckus +2
Given a Markov decision process (MDP) and a linear-time (-regular or LTL) specification, the controller synthesis problem aims to compute the optimal policy that satisfies the s…
Patch Tracking-based Streaming Tensor Ring Completion for Visual Data Recovery
Yicong He, George K. Atia
Tensor completion aims to recover the missing entries of a partially observed tensor by exploiting its low-rank structure, and has been applied to visual data recovery. In applicat…
