Natural Language Descriptions of Deep Visual Features

Hernandez, Evan, Schwettmann, Sarah, Bau, David et al.

Understand

Some neurons in deep networks specialize in recognizing highly specific perceptual, structural, or semantic features of inputs.

  • In computer vision, techniques exist for identifying neurons that respond to individual concept categories like colors, textures, and object classes.
  • But these techniques are limited in scope, labeling only a small subset of neurons and behaviors in any network.
  • Is a richer characterization of neuron-level computation possible? We introduce a procedure (called MILAN, for mutual-information-guided linguistic annotation of neurons) that automatically labels neurons with open-ended, compositional, natural language descriptions.
