SPEEDING UP LATENT SEMANTIC ANALYSIS - A Streamed Distributed Algorithm for SVD Updates

Abstract

Since its inception 20 years ago, Latent Semantic Analysis (LSA) has become a standard tool for robust, unsupervised inference of semantic structure from text corpora. At the core of LSA is the Singular Value Decomposition algorithm (SVD), a linear algebra routine for matrix factorization. This paper introduces a streamed distributed algorithm for incremental updates, which allows the factorization to be computed rapidly in a single pass over the input matrix on a cluster of autonomous computers.
