A structured workflow wrapper that chains data preprocessing steps directly to a Random Forest estimator for clean, leak-free machine learning.

The Scikit-learn Random Forest pipeline bundles feature engineering (such as SimpleImputer and OneHotEncoder) and a RandomForestClassifier or RandomForestRegressor into a single, cohesive estimator. By wrapping these sequential operations, the pipeline prevents data leakage during cross-validation (ensuring transformers only fit on training folds) and simplifies deployment. Instead of managing separate transformation steps and model calls, you trigger the entire workflow (from raw features to ensemble predictions) with a single call to fit or predict.

### [Building an ML Decision Lab for Agriculture: Turning Predictions into Learning](https://lausanne.aitinkerers.org/talks/rsvp_4vwa4V9v2ek)

FarmBuddy is an interactive machine learning decision-support system built with Streamlit and a Random Forest regression pipeline. Users can modify agricultural inputs such as crop type, fertilizer usage, land area, and season, then observe how model predictions change in real time. Beyond prediction, the system includes decision logging, before-and-after scenario comparison, input validation, and a learning summary layer designed to help users understand how machine learning models respond to changing conditions. During the demo, I will show the live application, model inference workflow, session-state architecture, and the decision comparison engine.
