Hierarchical sparse coding
Web28 de jun. de 2013 · Complex real-world signals, such as images, contain discriminative structures that differ in many aspects including scale, invariance, and data channel. While progress in deep learning shows the importance of learning features through multiple layers, it is equally important to learn features through multiple paths. We propose Multipath … WebHierarchical Sparse Coding We focus on the problem of extracting higher-level features of images by learning a second layer of sparse-coding bases on top of the first-layer activations. One desirable prop erty of high-level features is their invariance to small transformations, such as rotation or scaling.

WebRecently, sparse representation (SR) methods (dictionary learning and coding) have been introduced for signature modeling and verification with promising results. In this paper, we propose an extension of the SR framework by introducing the idea of embedding the atoms of a dictionary in a directed tree.
