Canonical correlation analysis: an overview with application to learning methods

Neural Comput. 2004 Dec;16(12):2639-64. doi: 10.1162/0899766042321814.

Abstract

We present a general method using kernel canonical correlation analysis to learn a semantic representation to web images and their associated text. The semantic space provides a common representation and enables a comparison between the text and images. In the experiments, we look at two approaches of retrieving images based on only their content from a text query. We compare orthogonalization approaches against a standard cross-representation retrieval technique known as the generalized vector space model.
