Goal

Build a predictive model for the Mitsui&Co. competition using lag-based signals and a reproducible inference workflow.

What I did

• Implemented a single-lag + grouped-lag approach for organizing targets/features
• Trained an ExtraTrees-based model as a strong non-linear baseline
• Structured the notebook for Kaggle submission (stable paths, fixed seed, clean sections)
