Theory of Mind as Test-Time Mitigation against Adversarial Communication (Nancirose Piazza - SAIL)

In Cooperative Multi-Agent Reinforcement Learning, there are training time defenses against adversarial communication. However, these types of defenses are expensive and require retraining if the underlying agent policies are retrained. We propose a test-time mitigation against adversarial communication using a mechanism designed from theory of mind concepts and provide empirical results of its performance preservation after readaptation training in comparison to another message filtering defense against adversarial communication, namely the Variational Auto-Encoding Bayes.
