Robotic learning algorithms based on reinforcement, self-supervision, and imitation can acquire end-to-end controllers from raw sensory inputs such as images. What is machine learning? Everything you need to know. Recall from Chapter 4 (specifically, Figure 4. figuration that methods based on machine learning could potentially offer. Thus, Pareto Q-learning is. We present an architecture of distributed sensor and decision agents that learn how to identify normal and abnormal states of the network using Reinforcement Learning (RL). One of the simplest approaches is to independently train each agent to maximize their individual reward while treating other agents as part of the environment [6, 22].
