tidylearn

Machine Learning for Tidynauts

Overview

tidylearn provides a unified tidyverse-compatible interface to R’s machine learning ecosystem. It wraps proven packages like glmnet, randomForest, xgboost, e1071, cluster, and dbscan - you get the reliability of established implementations with the convenience of a consistent, tidy API.

What tidylearn does:

Provides one consistent interface (tl_model()) to 20+ ML algorithms
Returns tidy tibbles instead of varied output formats
Offers unified ggplot2-based visualization across all methods
Enables pipe-friendly workflows with %>%
Orchestrates complex workflows combining multiple techniques

What tidylearn is NOT:

A reimplementation of ML algorithms (uses established packages under the hood)
A replacement for the underlying packages (you can access the raw model via model$fit)

Why tidylearn?

Each ML package in R has its own API, output format, and conventions. tidylearn provides a translation layer so you can:

Without tidylearn	With tidylearn
Learn different APIs for each package	One API for everything
Write custom code to extract results	Consistent tibble output
Create different plots for each model	Unified visualization
Manage package-specific quirks	Focus on your analysis

The underlying algorithms are unchanged - tidylearn simply makes them easier to use together.

Installation

# Install from CRAN
install.packages("tidylearn")

# Or install development version from GitHub
# devtools::install_github("ces0491/tidylearn")

Quick Start

Unified Interface

A single tl_model() function dispatches to the appropriate underlying package:

library(tidylearn)

# Classification -> uses randomForest::randomForest()
model <- tl_model(iris, Species ~ ., method = "forest")

# Regression -> uses stats::lm()
model <- tl_model(mtcars, mpg ~ wt + hp, method = "linear")

# Regularization -> uses glmnet::glmnet()
model <- tl_model(mtcars, mpg ~ ., method = "lasso")

# Clustering -> uses stats::kmeans()
model <- tl_model(iris[,1:4], method = "kmeans", k = 3)

# PCA -> uses stats::prcomp()
model <- tl_model(iris[,1:4], method = "pca")

Tidy Output

All results come back as tibbles, ready for dplyr and ggplot2:

# Predictions as tibbles
predictions <- predict(model, new_data = test_data)

# Metrics as tibbles
metrics <- tl_evaluate(model, test_data)

# Easy to pipe
model %>%
  predict(test_data) %>%
  bind_cols(test_data) %>%
  ggplot(aes(x = actual, y = prediction)) +
  geom_point()

Access the Underlying Model

You always have access to the raw model from the underlying package:

model <- tl_model(iris, Species ~ ., method = "forest")

# Access the randomForest object directly
model$fit  # This is the randomForest::randomForest() result

# Use package-specific functions if needed
randomForest::varImpPlot(model$fit)

Wrapped Packages

tidylearn provides a unified interface to these established R packages:

Supervised Learning

Method	Underlying Package	Function Called
`"linear"`	stats	`lm()`
`"polynomial"`	stats	`lm()` with `poly()`
`"logistic"`	stats	`glm(..., family = binomial)`
`"ridge"`, `"lasso"`, `"elastic_net"`	glmnet	`glmnet()`
`"tree"`	rpart	`rpart()`
`"forest"`	randomForest	`randomForest()`
`"boost"`	gbm	`gbm()`
`"xgboost"`	xgboost	`xgb.train()`
`"svm"`	e1071	`svm()`
`"nn"`	nnet	`nnet()`
`"deep"`	keras	`keras_model_sequential()`

Unsupervised Learning

Method	Underlying Package	Function Called
`"pca"`	stats	`prcomp()`
`"mds"`	stats, MASS, smacof	`cmdscale()`, `isoMDS()`, etc.
`"kmeans"`	stats	`kmeans()`
`"pam"`	cluster	`pam()`
`"clara"`	cluster	`clara()`
`"hclust"`	stats	`hclust()`
`"dbscan"`	dbscan	`dbscan()`

Integration Workflows

Beyond wrapping individual packages, tidylearn provides orchestration functions that combine multiple techniques:

Dimensionality Reduction + Supervised Learning

# Reduce dimensions before classification
reduced <- tl_reduce_dimensions(iris, response = "Species",
                                method = "pca", n_components = 3)
model <- tl_model(reduced$data, Species ~ ., method = "logistic")

Cluster-Based Feature Engineering

# Add cluster membership as a feature
enriched <- tl_add_cluster_features(data, response = "target",
                                    method = "kmeans", k = 3)
model <- tl_model(enriched, target ~ ., method = "forest")

Semi-Supervised Learning

# Use clustering to propagate labels to unlabeled data
model <- tl_semisupervised(data, target ~ .,
                          labeled_indices = labeled_idx,
                          cluster_method = "kmeans")

AutoML

# Automatically try multiple approaches
result <- tl_auto_ml(data, target ~ .,
                    time_budget = 300)
result$leaderboard

Unified Visualization

Consistent ggplot2-based plotting regardless of model type:

# Generic plot method works for all model types
plot(forest_model)       # Automatic visualization based on model type
plot(linear_model)       # Diagnostic plots for regression
plot(pca_result)         # Variance explained for PCA

# Specialized plotting functions for unsupervised learning
plot_clusters(clustering_result, cluster_col = "cluster")
plot_variance_explained(pca_result$fit$variance_explained)

# Interactive dashboard for detailed exploration
tl_dashboard(model, test_data)

Philosophy

tidylearn is built on these principles:

Transparency: The underlying packages do the real work. tidylearn makes them easier to use together without hiding what’s happening.
Consistency: One interface, tidy output, unified visualization - across all methods.
Accessibility: Focus on your analysis, not on learning different package APIs.
Interoperability: Results work seamlessly with dplyr, ggplot2, and the broader tidyverse.
