Abstract

We present a motivational system for an agent undergoing reinforcement learning (RL), which enables it to balance multiple drives, each of which is satiated by different types of stimuli. Inspired by drive reduction theory, it uses Minor Component Analysis (MCA) to model the agent’s internal drive state, and modulates incoming stimuli on the basis of how strongly the stimulus satiates the currently active drive. The agent’s dynamic policy continually changes through least-squares temporal difference updates. It automatically seeks stimuli that first satiate the most active internal drives, then the next most active drives, etc. We prove that our algorithm is stable under certain conditions. Experimental results illustrate its behavior.
