class BaggingTrees(x: MatrixD, y: VectorI, fname_: Array[String], k: Int, cname_: Array[String], conts: Set[Int], hparam: HyperParameter) extends Classifier, ...FitC

The BaggingTrees class uses several randomly built descision trees for classification. It randomly selects sub-samples of bRatio * x.dim size from the data x and y to build nTrees decision trees. The classify method uses voting from all of the trees. Note: this classifier does not select sub-features to build the trees.

The class with most votes is selected as the classification of z. Using a distance metric, the kappa vectors nearest to z are found in the training data, which is stored row-wise in the data matrix x. The corresponding classifications are given in the vector y, such that the classification for vector x(i) is given by y(i). FIX - cross validation uses test data for decision making, so when kappa = 1, acc = 100%

The classifier is TAN allowing each xj to utilize information from its x-parant.

The TANBayes class implements an Integer-Based TAN Bayes Classifier, which is a commonly used such classifier for discrete input data. The classifier is trained using a data matrix x and a classification vector y. Each data vector in the matrix is classified into one of k classes numbered 0, ..., k-1. Prior probabilities are calculated based on the population of each class in the training-set. Relative posterior probabilities are computed by multiplying these by values computed using conditional probabilities. stored in Conditional Probability Tables (CPTs).
