Struct TrainResult 

Source 
pub(crate) struct TrainResult {
    pub(crate) tree: SerializedTree,
    pub(crate) nr_train: usize,
    pub(crate) nr_pids_train: usize,
    pub(crate) holdout_len: usize,
    pub(crate) mae_tree: f64,
    pub(crate) mae_ema: f64,
    pub(crate) corr: f64,
}
Expand description

Result of one training run, handed back from the worker thread. The metrics are computed on the held-out slice so the publish gate and the reported numbers describe out-of-sample error.

Fields§

§tree: SerializedTree§nr_train: usize

Samples the tree was fit on.

§nr_pids_train: usize

Distinct pids in the fit slice, the concentration input for the per-pid cap.

§holdout_len: usize

Samples of the held-out evaluation slice.

§mae_tree: f64

Tree MAE on the holdout, in nsecs.

§mae_ema: f64

Exact per-sample EMA-baseline MAE on the holdout, in nsecs.

§corr: f64

Pearson correlation of tree predictions and labels on the holdout.
