Naive Bayes Classifier: Part 2. Characterization and Evaluation

Closed-form solutions are sweet. No hand-wringing/waving required to make a point. Given the assumptions, the model predictions are exact so we can readily evaluate the impact of assumptions. And, we get the means to evaluate alternate (e.g. numerical) approaches applied to these same limiting cases with the exact solution. We are… Read more »

Naive Bayes Classifier: A Geometric Analysis of the Naivete. Part 1

The curse of dimensionality is the bane of all classification problems. What is the curse of dimensionality? As the number of features (dimensions) increase linearly, the amount of training data required for classification increases exponentially. If the classification is determined by a single feature we need a-priori classification data over… Read more »
