Policy Gradient Variance Reduction

Compute variance reduction from baseline subtraction, reward normalization, and advantage estimation in REINFORCE and PPO policy gradient methods

Each component has a specific meaning:

• Baseline subtraction — The baseline subtraction recorded for the patient or scenario being assessed.
• Reward normalization — The reward normalization recorded for the patient or scenario being assessed.
• Advantage estimation in REINFORCE — The advantage estimation in reinforce recorded for the patient or scenario being assessed.
• PPO policy gradient methods — The ppo policy gradient methods recorded for the patient or scenario being assessed.

Note: Interpret the policy gradient result against the clinical thresholds and context described above.

Enter the baseline subtraction, reward normalization, advantage estimation in REINFORCE, PPO policy gradient methods for the patient or scenario you are assessing. Compute variance reduction from baseline subtraction, reward normalization, and advantage estimation in REINFORCE and PPO policy gradient methods. Use the policy gradient result to inform your clinical assessment.
