Recently, Fourier and cosine discrete transformations have been proposed to improve document ranking. The methods are advantageous in that they allow the use of spatial information on the presence of a term rather than a count of the term frequency. Further improvement of the approach can be reached by application of fast realizations of discrete transforms. The latter can also obtain a neural implementation.
