Expand description

Per-step training statistics for the SAC trainer.

Analogous to crate::train::dqn::DQNStepStatsBurn. Returned by SacTrainer::train_step once a gradient update has actually run.

Fields§

§critic_loss: f64

Mean MSE critic loss across the two online critics for this batch.

§actor_loss: f64

Actor (policy) loss for this batch.

§alpha_loss: f64

Entropy-temperature loss (0.0 when auto_alpha is disabled).

§alpha: f64

Current entropy temperature alpha.

§mean_q: f64

Mean of min(Q1, Q2)(s, a) over the batch on the stored actions.

§buffer_len: usize

Replay buffer fill level at the time of this update.
