calc_validation_metrics

Comprehensive validation metrics for a clustering result

Provides a unified tidyverse-compatible interface to R's machine
learning packages. Wraps established implementations from 'glmnet',
'randomForest', 'xgboost', 'e1071', 'rpart', 'gbm', 'nnet', 'cluster',
'dbscan', and others - providing consistent function signatures, tidy tibble
output, and unified 'ggplot2'-based visualization. The underlying algorithms
are unchanged; 'tidylearn' simply makes them easier to use together. Access
raw model objects via the $fit slot for package-specific functionality.
