{"year":"2011","abstract":[{"text":"We address the problem of metric learning for multi-view data, namely the construction of embedding projections from data in different representations into a shared feature space, such that the Euclidean distance in this space provides a meaningful within-view as well as between-view similarity. Our motivation stems from the problem of cross-media retrieval tasks, where the availability of a joint Euclidean distance function is a pre-requisite to allow fast, in particular hashing-based, nearest neighbor queries. We formulate an objective function that expresses the intuitive concept that matching samples are mapped closely together in the output space, whereas non-matching samples are pushed apart, no matter in which view they are available. The resulting optimization problem is not convex, but it can be decomposed explicitly into a convex and a concave part, thereby allowing efficient optimization using the convex-concave procedure. Experiments on an image retrieval task show that nearest-neighbor based cross-view retrieval is indeed possible, and the proposed technique improves the retrieval accuracy over baseline techniques.","lang":"eng"}],"publisher":"ML Research Press","publist_id":"3316","language":[{"iso":"eng"}],"status":"public","department":[{"_id":"ChLa"}],"oa_version":"None","page":"425 - 432","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference","conference":{"end_date":"2011-07-02","name":"ICML: International Conference on Machine Learning","start_date":"2011-06-28","location":"Bellevue, United States"},"citation":{"apa":"Quadrianto, N., &#38; Lampert, C.
