structboost.AllboostHistory

class structboost.AllboostHistory(selection, beta_path)

Bases: object

Trace information returned by allboost(…, return_history=True).

Parameters:

• selection (ndarray[tuple[Any, ...], dtype[int64]])

• beta_path (ndarray[tuple[Any, ...], dtype[float64]])

selection

Selected feature index at each step, shape (n_targets, stepno).

Type:

numpy.ndarray[tuple[Any, …], numpy.dtype[numpy.int64]]

beta_path

Coefficient path after each step, shape (n_targets, stepno, n_features). This can be memory-intensive; only enabled when explicitly requested.

Type:

numpy.ndarray[tuple[Any, …], numpy.dtype[numpy.float64]]
