Trojan Horse Training for Breaking Defenses against Backdoor Attacks in Deep Learning

Arezoo Rajabi, Bhaskar Ramasubramanian, Radha Poovendran

Machine learning (ML) models that use deep neural networks are vulnerable to backdoor attacks. Such attacks involve the insertion of a (hidden) trigger by an adversary. As a conseq…

Privacy-Preserving Reinforcement Learning Beyond Expectation

Arezoo Rajabi, Bhaskar Ramasubramanian, Abdullah Al Maruf +1

Cyber and cyber-physical systems equipped with machine learning algorithms such as autonomous cars share environments with humans. In such a setting, it is important to align syste…

Shaping Advice in Deep Reinforcement Learning

Baicen Xiao, Bhaskar Ramasubramanian, Radha Poovendran

Reinforcement learning involves agents interacting with an environment to complete tasks. When rewards provided by the environment are sparse, agents may not receive immediate feed…

Agent-Temporal Attention for Reward Redistribution in Episodic Multi-Agent Reinforcement Learning

Baicen Xiao, Bhaskar Ramasubramanian, Radha Poovendran

This paper considers multi-agent reinforcement learning (MARL) tasks where agents receive a shared global reward at the end of an episode. The delayed nature of this reward affects…

Reinforcement Learning Beyond Expectation

Bhaskar Ramasubramanian, Luyao Niu, Andrew Clark +1

The inputs and preferences of human users are important considerations in situations where these users interact with autonomous cyber or cyber-physical systems. In these scenarios,…

Shaping Advice in Deep Multi-Agent Reinforcement Learning

Baicen Xiao, Bhaskar Ramasubramanian, Radha Poovendran

Multi-agent reinforcement learning involves multiple agents interacting with each other and a shared environment to complete tasks. When rewards provided by the environment are spa…
