Parameters ---------- y_true : array, shape = [n_samples] or [n_samples, n_classes] True binary labels in binary label indicators. y_score : array, shape = [n_samples] or [n_samples, n_classes] Target scores, can either be probability estimates of the positive class, confidence values, or binary decisions. average : {None, 'micro', 'macro', 'samples', 'weighted'}, default='macro' If ``None``, the scores for each class are returned. Otherwise, this determines the type of averaging performed on the data: ``'micro'``: Calculate metrics globally by considering each element of the label indicator matrix as a label. ``'macro'``: Calculate metrics for each label, and find their unweighted mean. This does not take label imbalance into account. ``'weighted'``: Calculate metrics for each label, and find their average, weighted by support (the number of true instances for each label). ``'samples'``: Calculate metrics for each instance, and find their average. Will be ignored when ``y_true`` is binary. sample_weight : array-like of shape (n_samples,), default=None Sample weights. binary_metric : callable, returns shape [n_classes] The binary metric function to use. Returns ------- score : float or array of shape [n_classes] If not ``None``, average the score, else return the score for each classes. )Nmicromacroweightedsampleszaverage has to be one of {0})binaryzmultilabel-indicatorz{0} format is not supportedr ) sample_weightNr r )rr)axisgr weights) ValueErrorformatrrrnprepeatshaperavelsummultiplyreshapeisclosendimzerosrangetakeasarrayfloataverage) binary_metricy_truey_scorer$raverage_optionsy_typenot_average_axis score_weightaverage_weight n_classesscorecy_true_c y_score_cs H/var/www/html/venv/lib/python3.13/site-packages/sklearn/metrics/_base.py_average_binary_scorer3sDVFO%7>>OPP F #F 776==fEFF VMJJF];  F'"G LN'  #99\<<?CL--/ J   #VV FBJJ|W$EFQN VVF3N ::n((*C 0 0 1 I %  {{a(||q//'* ./I HHi\ "E 9 ;;s)9;:@@BLL!+;L<BBD  LQ   % ZZ7N)*EA% &RZZ>?? c&[X5 [R"U5nURSnXUS- -S-n[R"U5nUS:HnU(a[R"U5OSn [ [ US55Hqun upX:Hn X:Hn[R"X5nU(a[R"U5X'XnXnU"UX/U 45nU"UX/U 45nUU-S- Xz'Ms [R"XyS9$)aAverage one-versus-one scores for multiclass classification. Uses the binary metric for one-vs-one multiclass classification, where the score is computed according to the Hand & Till (2001) algorithm. Parameters ---------- binary_metric : callable The binary metric function to use that accepts the following as input: y_true_target : array, shape = [n_samples_target] Some sub-array of y_true for a pair of classes designated positive and negative in the one-vs-one scheme. y_score_target : array, shape = [n_samples_target] Scores corresponding to the probability estimates of a sample belonging to the designated positive class label y_true : array-like of shape (n_samples,) True multiclass labels. y_score : array-like of shape (n_samples, n_classes) Target scores corresponding to probability estimates of a sample belonging to a particular class. average : {'macro', 'weighted'}, default='macro' Determines the type of averaging performed on the pairwise binary metric scores: ``'macro'``: Calculate metrics for each label, and find their unweighted mean. This does not take label imbalance into account. Classes are assumed to be uniformly distributed. ``'weighted'``: Calculate metrics for each label, taking into account the prevalence of the classes.
