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:

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

Unsupervised Learning

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:

1. Transparency: The underlying packages do the real work. tidylearn makes them easier to use together without hiding what's happening.

2. Consistency: One interface, tidy output, unified visualization - across all methods.

3. Accessibility: Focus on your analysis, not on learning different package APIs.

4. Interoperability: Results work seamlessly with dplyr, ggplot2, and the broader tidyverse.
