7. MLQuantify Methods

The table below lists all the quantification methods available in the mlquantify library, their references, multiclass support, and type (aggregative, meta, or non-aggregative).

Note

In binary classification problems, methods that do not natively support multiclass classification (marked No in the Multiclass column) remain applicable through standard reduction strategies like one-vs-rest or one-vs-one.
