"WebApr 9, 2024 · The core idea is to replace the deterministic policy π:s→a with a parameterized probability distribution π_θ(a s) = P (a s; θ). Instead of returning a single action, we sample actions from a probability distribution tuned by θ. A stochastic policy might seem inconvenient, but it provides the foundation to optimize the policy.
