This paper describes a multisensorial person-identification system in which visual and acoustic cues are used jointly for person identification. A simple approach, based on the fusion of the lists of scores produced independently by a speaker-recognition system and a face-recognition system, is presented. Experiments are reported that show that the(More)
A memory-based system for autonomous indoor navigation is presented. The system was implemented as a follow-midline reflex on a robot that moves along the corridors of our institute. The robot estimates its position in the environment by comparing the visual input with images contained in its memory. Spatial positions are represented by classes. Memories(More)
An approximation of the Bayes decision rule and its implementation on a two-layered network are described. The net is trained in two phases: first, probabilities of the discrete-valued input features are learnt by applying a Good-Turing based estimator; second, net weights are estimated by applying an adaptive gradient descent technique. Experiments were(More)
