Salient Imagenet

Class: 626 (Lighter), Feature: 1642

This feature is spurious for class Lighter. It is the third most important feature for class Lighter.

Below, we display the five Lighter images that most highly activate the feature, along with the Neural Activation Map (heatmap) and Feature Attack for each image. These are the same as the images shown to crowdworkers to annotate this class-feature pair.

We additionally provide the full responses of the five crowdworkers that annotated this pair, as well as links to other related pairs (i.e. same class or same feature).
