Truly Deterministic Policy Optimization (TDPO) is a model-free policy gradient method which trains reinforcement learning agents without requiring a Gaussian stochasticity in the policy's action. This is why we call it truly deterministic; not only it uses deterministic policy gradients, but also it performs deterministic policy search.2022. 2. Learning Rate. The learning rate or step size determines to what extent newly acquired information overrides old information. A factor of 0 makes the agent learn nothing (exclusively exploiting prior knowledge), while a factor of 1 makes the agent consider only the most recent information (ignoring prior knowledge to explore possibilities).
