Salient Imagenet

Class: 536 (Dock), Feature: 76

This feature is spurious for class Dock. It is the fourth most important feature for class Dock.

Below, we display the five Dock 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).

Main Focus	Confidence	Explanation
Background	3	Very little of the docking is in the red areas. the majority of the red focus is the water in the background or foreground. the water is necessary for docking but the red areas could be better placed to include more of the physical docking.
Separate Object	2	Focus on the boat
Background	4	Water in the background of dock
Background	4	The red is on the water behind the dock.
Main Object	2	The focus is mostly on the dock, but in some photos the highlighted area seems to be the boat and the water, while the dock is still partly being highlighted.
