Matching functional sites is a key problem for the understanding of protein function and evolution. The commonly used graph theoretic approach, and other related approaches, require adjustment of a matching distance threshold a priori according to the no
The procedure is called dimensionality reduction. The rows in T are the term vectors in the LSI space and the rows in D are the document vectors in the LSI space. Document–document, term–term, and term–document similarities are computed in the reduced dimensional approximation to A. 4.2....
