摘要：
The Bayes classifier is a probabilistic machine learning model based on Bayes' theorem, which calculates the likelihood that a data point belongs to a particular class. It uses prior knowledge of the class distributions and the probability of features given each class to compute the posterior probability—that is, the probability that the data point is in a specific class after observing the features. The classifier then assigns the data point to the class with the highest posterior probability. This approach is widely used due to its simplicity, efficiency, and effectiveness, especially in scenarios with well-understood probability distributions or high-dimensional data. In this talk, a specific binary Bayes classifier will be introduced including its framework as well as its fast implementation. Further, its applications in visual object recognition and seizure prediction will be presented. In the end, some future applications will be discussed.
