Struct TrainingStats

Source

pub struct TrainingStats {
    pub total_loss: f64,
    pub policy_loss: f64,
    pub value_loss: f64,

Expand description

Training statistics from a policy update.

Mirrors crate::train::ppo::TrainingStats field-for-field for the quantities a simulator typically needs to log. Stays a separate struct so the multi-agent message surface does not pull in the per-update aggregator.

Fields§

§total_loss: f64

Total loss (weighted sum of policy / value / entropy / aux).

§policy_loss: f64

Policy loss component.

§value_loss: f64

Value loss component.

§entropy: f64

Entropy bonus.

§kl_divergence: f64

KL divergence (for monitoring).

§step: usize

Number of gradient updates completed.

§avg_reward: Option<f64>

Average episode reward (if available).
