- TD_ClassificationEvaluator
- Computes the Confusion matrix, precision, recall, and F1-score based on the observed labels (true labels) and the predicted labels.
- TD_HNSWSummary
- Takes the ModelTable generated from TD_HNSW as input and converts the ModelTable data into readable format.
- 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_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_TrainTestSplit
- Simulates model performance on new data.
