Utilities

General-purpose helpers used across Skchange: tag classes that declare estimator capabilities, input and parameter validators, and segmentation conversions.

Tags

Dataclasses that declare detector and interval-scorer capabilities.

SkchangeTags(estimator_type, target_tags, ...)	Extended tags for skchange estimators.
SkchangeInputTags([one_d_array, ...])	Extended input tags for skchange estimators.
ChangeDetectorTags([linear_trend_segment])	Tags specific to change detection estimators.
IntervalScorerTags([score_type, aggregated, ...])	Tags specific to interval scorer estimators.

Validation

Input and parameter validation helpers.

validate_data(_estimator, /, X, **kwargs)	Validate X and set n_features_in_ and n_samples_in_ on the estimator.
check_interval_scorer(scorer, *[, ...])	Check if the given scorer is a valid interval scorer.
check_interval_specs(interval_specs, n_cols, *)	Validate an interval_specs array.
check_penalty(penalty, *[, ...])	Check if the given penalty is valid.

Segmentation

Conversions between dense per-sample segment labels and sparse changepoint indices.

changepoints_to_labels(changepoints, n_samples)	Convert changepoint indices to per-sample segment labels.
labels_to_changepoints(labels)	Convert per-sample segment labels to changepoint indices.
