Functions
Functions that are not part of a class:

train(array $samples, array $targets)   X-Ref
Train a binary classifier in the OvR style


reset()   X-Ref
Resets the classifier and the vars internally used by OneVsRest to create multiple classifiers.


trainByLabel(array $samples, array $targets, array $allLabels = [])   X-Ref
No description

getClassifierCopy()   X-Ref
Returns an instance of the current class after cleaning up OneVsRest stuff.


predictSample(array $sample)   X-Ref

return: mixed

binarizeTargets(array $targets, $label)   X-Ref
Groups all targets into two groups: Targets equal to
the given label and the others

$targets is not passed by reference nor contains objects so this method
changes will not affect the caller $targets array.

return: array Binarized targets and target's labels
