# Policy gradient mathematical notation

Policy gradient is a recurring research-paper notation family. Differentiates expected policy performance with respect to policy parameters so gradient…

## Public overview

Policy gradient is a recurring research-paper notation family. Differentiates expected policy performance with respect to policy parameters so gradient ascent can improve action probabilities.

Policy gradient: Differentiates expected policy performance with respect to policy parameters so gradient ascent can improve action probabilities. Example: Increase log probability for sampled actions in proportion to their return.
