Isometric Projection
Recently the problem of dimensionality reduction has received a lot of interests in many fields of information processing. We consider the case where data is sampled from a low dimensional manifold which is embedded in high dimensional Euclidean space. The most popular manifold learning algorithms include Locally Linear Embedding, ISOMAP, and Laplacian Eigenmap. However, these algorithms are no...
متن کاملAdaptively Weighted Subpattern-Based Isometric Projection for Face Recognition
In this paper, we propose an adaptively weighted subpatternbased isometric projection (Aw-spIsoP) algorithm for face recognition. Unlike IsoP (isometric projection) based on a whole image pattern, the proposed Aw-spIsoP method operates on sub-patterns partitioned from an original whole face image and separately extracts corresponding local sub-features from them. Moreover, the adjacency graph u...
متن کاملA Quasi-isometric Embedding Algorithm
The Whitney embedding theorem gives an upper bound on the smallest embedding dimension of a manifold. If a data set lies on a manifold, a random projection into this reduced dimension will retain the manifold structure. Here we present an algorithm to find a projection that distorts the data as little as possible.

متن کاملA Novel Collaborative Filtering Algorithm Based on Bipartite Network Projection
In this paper, we present a collaborative filtering algorithm based on the bipartite network projection. First, we project the bipartite network to a weighted directed one-mode network in order to retain original information and extract hidden information. The weight of an edge denotes how important the ending vertex is to the starting one. Then, we implement the algorithm using projection netw...
