DEVICES, SYSTEMS, AND METHODS FOR LARGE-SCALE LINEAR DISCRIMINANT ANALYSIS OF IMAGES
First Claim
1. A method comprising:
- obtaining a training set of images, wherein the images in the training set of images are each associated with at least one category in a plurality of categories;
organizing the images in the training set of images into a category hierarchy based on the training set of images and on the plurality of categories, wherein the category hierarchy identifies each of the categories in the plurality of categories as at least one of a parent category and child category; and
generating a subspace map for each parent category based on images associated with respective child categories of the parent category, thereby generating a plurality of subspace maps.

Abstract
Systems, devices, and methods for generating hierarchical subspace maps obtain a training set of images, wherein the images in the training set of images are each associated with at least one category in a plurality of categories; organize the images in the training set of images into a category hierarchy based on the training set of images and on the plurality of categories, wherein the category hierarchy identifies each of the categories in the plurality of categories as at least one of a parent category and child category; and generate a subspace map for each parent category based on images associated with respective child categories of the parent category, thereby generating a plurality of subspace maps.

12. A computing device comprising:
-
one or more computer-readable media; and one or more processors coupled to the computer-readable media and configured to cause the computing device to perform operations including obtaining a training set of images; assigning the images to a category in a category hierarchy, wherein the category hierarchy identifies each of the categories in the plurality of categories as at least one of a parent category and child category; and generating a subspace map for each parent category based on images assigned to respective child categories of the parent category, thereby generating a plurality of subspace maps. - View Dependent Claims (13, 14, 15)

16. One or more computer-readable media storing instructions that, when executed by one or more computing devices, cause the computer devices to perform operations comprising:
-
obtaining a training set of images; assigning the images to a category in a category hierarchy, wherein the category hierarchy identifies each of the categories in the plurality of categories as at least one of a parent category and child category; and generating a subspace map for each parent category based on images assigned to respective child categories of the parent category, thereby generating a plurality of subspace maps. - View Dependent Claims (17, 18)
