Vecharynski, Eugene; Saad, Yousef Fast updating algorithms for latent semantic indexing. (English) Zbl 1306.65193 SIAM J. Matrix Anal. Appl. 35, No. 3, 1105-1131 (2014). The authors analyze “a few algorithms for updating the approximate singular value decomposition (SVD) in the context of information retrieval by latent semantic indexing (LSI) methods”. They propose a unified framework based on Rayleigh-Ritz projection methods. Numerical experiments are also discussed.
