Class: 107 (Jellyfish), Feature: 981

This feature is core for class Jellyfish. It is the fourth most important feature for class Jellyfish.

Below, we display the five Jellyfish 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
Main Object	3	Red focus is on jelly fish.
Main Object	5	Focus is on a part of the main object.
Background	3	Highlighted visual attributes is on the water surrounding the jellyfish.
Main Object	5	Focus is set on main object jellyfish.
Background	2	In the images with larger jellyfish, the focus appears to be on the background. in the images with smaller jellyfish is appears to be focused on the jellyfish themselves. my guess is that in such images the algorithm mistakes the empty space for a large jellyfish and thinks the smaller jellyfish are the background.
