The discussion so far has derived the independent feature model, that is, the naive Bayes probability model. The naive Bayes classifier combines this model with a decision rule. One common rule is to pick the hypothesis that is most probable; this is known as the maximum a posteriori or MAP decision rule. Clustering and nearest-neighbour methods are ideally suited for use with numeric data. However, data often use using categorical values, i.e., names or symbols. In this situation, it may be better to use a probabilistic method, such as the Naive Bayes Classifier (NBC). Probabilities Sep 11, 2017 · What is Naive Bayes algorithm? It is a classification technique based on Bayes’ Theorem with an assumption of independence among predictors. In simple terms, a Naive Bayes classifier assumes that the presence of a particular feature in a class is unrelated to the presence of any other feature. .

Data Clustering - Data Clustering Using Naive Bayes Inference. By James McCaffrey | March 2013. Data clustering is a machine-learning technique that has many important practical applications, such as grouping sales data to reveal consumer-buying behavior, or grouping network data to give insights into communication patterns. I've built a little naive Bayesian classifier that works with Boolean and real values. Boolean distributions are dealt with via Bernoulli distributions, while real valued data are dealt with kernel mixture estimators. I'm currently in the process of adding count data in.
