A comprehensive tutorial demonstrating the complete MLwrap workflow is available. The tutorial provides detailed guidance on data preprocessing, model building, hyperparameter tuning, model evaluation, and sensitivity analysis across all supported machine learning algorithms (Neural Networks, Random Forests, SVM, and XGBoost) within the Knowledge Discovery in Databases (KDD) framework.

While MLwrap provides a streamlined and user-friendly interface for implementing machine learning workflows, the underlying models represent sophisticated algorithms with substantial theoretical and computational complexity. The tutorial bridges this gap by explaining the rationale behind preprocessing decisions, hyperparameter choices, and interpretation of model outputs. Understanding these concepts ensures appropriate application of the methods, proper interpretation of results, and awareness of potential limitations in specific contexts.
The tutorial demonstrates practical applications through complete workflows, helping users navigate the balance between methodological rigor and implementation simplicity that MLwrap offers. This is particularly valuable for researchers transitioning from traditional statistical methods to machine learning approaches, or those seeking to ensure reproducible and theoretically sound applications in their work.
Users are strongly encouraged to consult the tutorial for detailed examples and best practices.
This paper is also interesting for ML users as it serves as a primer for estimating ML models using Python code, particularly in the context of Social, Health, and Behavioral research.
