Struct BcEpochStats

pub struct BcEpochStats {
    pub loss: f64,
    pub accuracy: f64,
}

Expand description

Per-epoch behavioral-cloning statistics.

Both fields are finite host-side f64s aggregated over the epoch’s minibatches. Purpose-built (rather than reusing the RL stats structs) because BC has no policy/value/entropy decomposition — just the supervised loss and the action-match accuracy.

Fields§

§loss: f64

Mean cross-entropy loss over the epoch’s minibatches.

§accuracy: f64

Mean action-match accuracy in [0, 1]: the fraction of examples whose argmax-logit action matched the expert label, averaged over the epoch.
