A new method called Neuron-level Balance between Stability and Plasticity (NBSP) has been proposed for deep reinforcement learning.
NBSP focuses on the trade-off between retaining existing skills (stability) and learning new knowledge (plasticity).
The method identifies RL skill neurons crucial for knowledge retention and introduces a framework to target these neurons for preserving existing skills while enabling adaptation to new tasks.
Experimental results on Meta-World and Atari benchmarks show that NBSP outperforms existing approaches in balancing stability and plasticity.
