Scan likelihood evaluation in FastSLAM using binary Bayes filter

In probability theory, statistics, and machine learning, recursive Bayesian estimation, also known as a Bayes filter, is a general probabilistic approach for estimating an unknown probability density function (PDF) recursively over time using incoming measurements and a mathematical process model. The process relies heavily upon mathematical concepts and models that are theorized within a study of prior and posterior probabilities known as Bayesian statistics. WebFeb 3, 2010 · Bayes’ Theorem forms the mathematical foundation of the Naive Bayes spam filtering technique, which is widely using by email services nowadays to keep spam out of our inboxes.
