binary and multiclass classificationconfusion matriximage classificationsupport vector machine (SVM)Support vector machines (SVMs) have considerable potential for supervised classification analyses, but their binary nature has been a constraint on their use in remote sensing. This typically requires a multi...

Training a binary classification model To train the model, we'll use an algorithm to fit the training data to a function that calculates the probability of the class label being true (in other words, that the patient has diabetes). Probability is measured as a value between 0.0 and 1.0, ...
Our implementation use two classes, theBinaryBalancerand theMulticlassBalancer, to perform their respective adjustments. Initializing a balancer with the true label, the predicted label, and the protected attribute will produce a report with the groupwise true- and false-positive rates. The rest of ...
Binary decision tree for multiclass classification expand all in page Description A ClassificationTree object represents a decision tree with binary splits for classification. An object of this class can predict responses for new data using predict. The object contains the data used for training, so...
Use for binary classification when training data is not balanced. weight_of_positive_examples Control the balance of positive and negative weights, useful for unbalanced classes. A typical value to consider: sum(negative cases) / sum(positive cases). ...
The goal of multi-class classification is to classify an input x into one of J > 2 class labels. The LogitBoost algorithm (Friedman et al., 2000) fits an additive symmetric logistic model via the maximum-likelihood principle. This fitting proceeds iteratively by selecting weak learners and comb...
