Joint Image and Word Sense Discrimination For Image Retrieval

We study the task of learning to rank images given a text query, a problem that is complicated by the issue of multiple senses. That is, the senses of interest are typically the visually distinct concepts that a user wishes to retrieve. In this paper, we propose to learn a ranking function that optimizes the ranking cost of interest and simultaneously discovers the disambiguated senses of the query that are optimal for the supervised task. Note that no supervised information is given about the senses. Experiments performed on web images and the ImageNet dataset show that using our approach leads to a clear gain in performance.
