Knowledge distillation

Bilgi damıtma

D2 · Generative AI, capabilities and limitations

Knowledge distillation trains a student model using information supplied by a teacher model or ensemble.

Review status: 2026-12-05

Technical explanation

The student learns from teacher outputs or representations; this can support a more compact model.

Conceptual boundaries

Distillation transfers learned behavior through training; quantization changes numerical representation.

Provider-neutral example

Illustrative: a team trains a compact text classifier using a larger classifier’s predictions, then evaluates it on held-out cases.

Limitations

Compression results in particular studies do not guarantee that every student retains all teacher capabilities.
