I built a solution for the Amazon ML Challenge 2025 on my GitHub, focusing on smart product pricing using text descriptions and numeric cues.
The repository started 2026-01, last updated 2026-02.
The dataset used in this project is not included in this repository.
Combined TF‑IDF (1,000 dimensions) with numeric features into a 1,011‑dimensional vector.
Ensemble weights: Random Forest (40% weight), Gradient Boosting (40% weight), Ridge Regression (20% weight).
Validation SMAPE: 63.92% and Validation MAE: $13.87.
Predicted price range: $4.82 to $9,402.11, most predictions fall between $10 and $50.
