TD_SHAP
Computes the contribution of each feature in a prediction as as average marginal contribution of the feature value across all possible coalitions.
TD_Silhouette
Determines how well the data is clustered among clusters.
TD_ClassificationEvaluator
Computes the Confusion matrix, precision, recall, and F1-score based on the observed labels (true labels) and the predicted labels.
TD_RegressionEvaluator
Computes metrics to evaluate and compare multiple models and summarizes how close predictions are to their expected values.
TD_ROC
Accepts a set of prediction-actual pairs for a binary classification model and calculates the True-positive rate (TPR), False-positive rate (FPR), The area under the ROC curve (AUC), and Gini coefficient values for a range of discrimination thresholds.
TD_TrainTestSplit
Simulates model performance on new data.
