About: Random projection

An Entity of Type: topical concept, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

In mathematics and statistics, random projection is a technique used to reduce the dimensionality of a set of points which lie in Euclidean space. Random projection methods are known for their power, simplicity, and low error rates when compared to other methods. According to experimental results, random projection preserves distances well, but empirical results are sparse. They have been applied to many natural language tasks under the name random indexing.
