Knowledge Transfer with Jacobian Matching

Srinivas, Suraj, Fleuret, Francois

Understand

Classical distillation methods transfer representations from a "teacher" neural network to a "student" network by matching their output activations.

  • Recent methods also match the Jacobians, or the gradient of output activations with the input.
  • However, this involves making some ad hoc decisions, in particular, the choice of the loss function.
  • In this paper, we first establish an equivalence between Jacobian matching and distillation with input noise, from which we derive appropriate loss functions for Jacobian matching.
