+end-to-end for the
 [credit risk model stability Kaggle competition](https://www.kaggle.com/competitions/home-credit-credit-risk-model-stability).
 
 1. Load data and perform feature engineering on DuckDB backend using IbisML
 2. Perform last-mile ML data preprocessing on DuckDB backend using IbisML
 3. Train two models using different frameworks:
     * An XGBoost model within a scikit-learn pipeline.
-    * A neural network with PyTorch and PyTorch Lightning
+    * A neural network with PyTorch and PyTorch Lightning.
 
 The aim of this competition is to predict which clients are more likely to default on their
 loans by using both internal and external data sources.
