In this paper, we demonstrate that this approach not only serves for the graph construction, but also represents an efficient and accurate alternative for out- ...
Abstract. A critical aspect of non-linear dimensionality reduction techniques is represented by the construction of the adjacency graph.
Abstract. A critical aspect of non-linear dimensionality reduction techniques is represented by the construction of the adjacency graph.
This is carried out by implementing an L1 minimization process to obtain the sparse representation of that sample as linear combination of the remaining ...
A framework based on sparse coding is proposed for out-of-sample embedding. · The locality preserving property is jointly used with sparse coding.
