Latent semantic indexing (LSI) is a method of information retrieval (IR) that relies heavily on the partial singular value decomposition (PSVD) of the term-document matrix representation of a data set.

Some numerical examples are given to confirm the performance of the algorithms.

In this talk, two different SVD update algorithms capable of treating an arbitrary number of new observations are introduced following the symmetric EVD philosophy.

These methods are compared to an SVD update method known from the literature.

In this paper a generalization of this method for computing the singular value decomposition of close-to-diagonal has repeated or “close” singular values it is possible to apply the direct method to split the problem in two with one part containing the well-separated singular values and one requiring the computation of the “close” singular values.

Efficiently updating an SVD-based data representation while keeping accurate track of the data mean when new observations are coming in is a common objective in many practical application scenarios.

The comparison criterion of interest is the theoretical computational complexity, it being understood that the dimension of the observation vectors is much larger than the number of observations.
