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 KNN_Classifier class is used to classify a new vector z into one of k classes. It works by finding its kappa nearest neighbors. These neighbors essentially vote according to their classification. 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%

class SimpleLogisticRegression(x: MatrixD, y: VectorI, fname_: Array[String], cname_: Array[String], hparam: HyperParameter) extends Classifier, FitC

The SimpleLogisticRegression class supports (binomial) logistic regression. In this case, x is two-dimensional [1, x_1]. Fit the parameter vector b in the logistic regression equation logit (p_y) = b dot x + e = b_0 + b_1 * x_1 + e where e represents the residuals (the part not explained by the model) and y is now binary.

class TANBayes(x: MatrixD, y: VectorI, fname_: Array[String], k: Int, cname_: Array[String], var vc: VectorI, hparam: HyperParameter) extends Classifier, BayesClassifier, FitC

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).

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