Researchers have developed PRIME (Plasticity Recovery In Multi-agent Environments), a novel framework designed to address the issue of dormant neurons in multi-agent reinforcement learning systems, particularly in dynamic environments. Unlike previous methods that assume stationary conditions or react only to external changes, PRIME focuses on the internal state of the network. It identifies and safely reinitializes neurons that are both activation-dormant and gradient-silent, thereby restoring learning capacity without disrupting useful representations. Tested on a UAV emergency communication simulator, PRIME demonstrated a significant improvement in performance over existing methods like MAPPO, reducing dormant neuron fractions and enhancing overall return.
