Network Dissection is an interpretability method for CNNs that evaluates the alignment between individual hidden units and a set of visual semantic concepts. By identifying the best alignments, units are given human interpretable labels across a range of objects, parts, scenes, textures, materials, and colors.

The measurement of interpretability proceeds in three steps:

  • Identify a broad set of human-labeled visual concepts.
  • Gather the response of the hidden variables to known concepts.
  • Quantify alignment of hidden variable−concept pairs.
