Estimating the Absolute Position of a Mobile Robot Using Position Probability Grids
In order to re-use existing models of the environment mobile robots must be able to estimate their position and orientation in such models. Most of the existing methods for positi...

Speech presence probability estimation based on temporal cepstrum smoothing
We propose a novel, robust estimator for the probability of speech presence at each time-frequency point in the short-time discrete Fourier domain. While existing estimators perfo...

A fast Monte Carlo algorithm for collision probability estimation
—In order to navigate safely, it is important to detect and to react to a potentially dangerous situation. Such a situation can be underlined by a judicious use of the locations ...

Estimating Word Translation Probabilities from Unrelated Monolingual Corpora Using the EM Algorithm
Selecting the right word translation among several options in the lexicon is a core problem for machine translation. We present a novel approach to this problem that can be traine...
