We propose a new classifier combination scheme for the ensemble of classifiers. The Pairwise Fusion Matrix (PFM) constructs confusion matrices based on classifier pairs and thus offers the estimated probability of each class based on each classifier pair. These probability outputs can then be combined and the final outputs of the ensemble of classifiers is reached using various fusion functions...

We study the structure of an S-box based on a fractional linear transformation applied on the Galois field [Formula: see text]. The algorithm followed is very simple and yields an S-box with a very high ability to create confusion in the data. The cryptographic strength of the new S-box is critically analyzed by studying the properties of S-box such as nonlinearity, strict avalanche, bit indepe...

Telefónica I+D has developed an automatic correction method specially focused on the adaptation of Internet text in order to be read by our text-to-speech system. The correction model detects errors by searching words in a dictionary, and then (if the word isn ́t found) correction candidates are generated by making elemental transformations (such as insertion, deletion, substitution or transposi...
