X-grams are a generalization of the n-grams, where the number of previous conditioning words is different for each case and decided from the training data. X-grams reduce perplexity with respect to tr...
. In EuroSpeech'95, we presented the first version of Sethos, the speech understanding system which has been developed at the UPC. In this paper some improvements are incorporated at different levels ...
In this paper we present a new personalisation algorithm for hypermedia databases, called GRAS (Gaussian Rating Adaptation Scheme), which combines content-based and social filtering. The goal is to fi...

. We find a numerical solution of an initial and boundary value problem. This problem is a parabolic integro-differential equation whose integral is the convolution product of a positive-definite weak...
The performances of the demiphone (a context dependent subword unit that models independently the left and the right parts of a phoneme) and the triphone are compared. Continuous density hidden Markov...
