}

Expand description

Per-step training statistics for the Burn DQN trainer.

Mirrors crate::train::dqn::DQNStepStats (tch path) field-for-field where the fields make sense for the Burn / non-prioritized path. Prioritized-replay fields (beta, mean_abs_td_error) are dropped because the Burn trainer does not yet implement prioritized replay (see module doc).

Fields§

§td_loss: f64

Mean Smooth-L1 (Huber) loss across the minibatch.

§mean_q: f64

Mean of Q(s, a) across the minibatch.

§epsilon: f64

ε used to draw the most recent action.

§buffer_len: usize

Replay buffer fill level at the time of this update.
