COSMic: A Coherence-Aware Generation Metric for Image Descriptions
Mert İnan, Piyush Sharma, Baber Khalid +3
Developers of text generation models rely on automated evaluation metrics as a stand-in for slow and expensive manual evaluations. However, image captioning metrics have struggled…
Survey of Recent Multi-Agent Reinforcement Learning Algorithms Utilizing Centralized Training
Piyush K. Sharma, Rolando Fernandez, Erin Zaroukian +3
Much work has been dedicated to the exploration of Multi-Agent Reinforcement Learning (MARL) paradigms implementing a centralized learning with decentralized execution (CLDE) appro…
Asynchronous Distributed Reinforcement Learning for LQR Control via Zeroth-Order Block Coordinate Descent
Gangshan Jing, He Bai, Jemin George +2
Recently introduced distributed zeroth-order optimization (ZOO) algorithms have shown their utility in distributed reinforcement learning (RL). Unfortunately, in the gradient estim…
Heterogeneous Noisy Short Signal Camouflage in Multi-Domain Environment Decision-Making
Piyush K. Sharma
Data transmission between two or more digital devices in industry and government demands secure and agile technology. Digital information distribution often requires deployment of…
