discriminatori

Discriminatori is the plural form of discriminatore in Italian, literally meaning 'discriminator' in English. The term refers to any agent—human, device, or algorithm—that differentiates between options, categories, or signals.

In artificial intelligence and machine learning, a discriminator is a model that classifies inputs into real vs generated, or into categories. In a generative adversarial network (GAN), the discriminator learns to distinguish real data from data produced by a generator, guiding the generator to improve.

In electronics and signal processing, a discriminator is a detector that extracts information from a modulated signal. For example, a frequency-modulation (FM) discriminator converts frequency variations into an audio or baseband signal, while other discriminators may demodulate amplitude or phase.

In statistics and decision theory, a discriminator or decision rule assigns observations to classes. A discriminant function or threshold-based rule is used in classification tasks.

In linguistics and philosophy, the term is used more generally to denote criteria or devices that separate alternatives; usage varies by field.
