Session Goal

The session aimed to refine machine learning models by integrating robust evaluation metrics and handling multiclass and multi-target classification challenges.

Key Activities

  • Refined the fit_model function to incorporate model evaluation metrics tailored for both classification and regression tasks.
  • Implemented 1-vs-Rest classification strategy to enhance performance in multiclass scenarios using Scikit-learn.
  • Refactored code to support multi-target classification, focusing on RandomForestClassifier, and improved diagnostics for feature importance.
  • Analyzed class imbalance issues within the model, providing insights and remediation strategies.
  • Conducted a detailed performance analysis of a classifier predicting marital status, identifying challenges with specific categories.

Achievements

  • Successfully integrated evaluation metrics into the fit_model function.
  • Enhanced model performance through 1-vs-Rest classification and improved multi-target handling.
  • Identified and proposed solutions for class imbalance issues.

Pending Tasks

  • Further testing and validation of the refactored models to ensure robustness across different datasets.
  • Implement additional strategies to address class imbalance, such as resampling techniques.
