🧠 ML-Projects

A curated collection of machine learning projects including real-world forecasting, structured competitions, and classical problems.


📂 Projects

  • Description:
    A Kaggle-style competition hosted on DACON, predicting building-level electricity consumption.

  • Focus:
    Feature engineering (time-based, building type), ensemble models, Optuna tuning.

  • Highlights:

    • Explored clustering-based splits and weighted VotingRegressor.
    • Achieved best SMAPE on public leaderboard around 6.99 ~ 7.00.

  • Description:
    Submissions and model experiments for the SCU AI Competition.

  • Focus:
    Feature engineering, clustering, ensemble modeling.

  • Result:
    🏆 Best AUC: 0.897686 (VotingClassifier with engineered features)


  • Description:
    A separate track of the SCU AI Competition held in 2025.

  • Focus:
    Structured daily experiment logs with feature engineering and model iteration.
    Includes Kaggle-style reproducibility and checkpointed submissions.


  • Description:
    Classic binary classification task on Titanic dataset.

  • Focus:
    Baseline experiments, ensemble methods, reproducible ML pipeline practice.


🛠 Tech Stack

  • Python, Jupyter Notebook
  • scikit-learn, XGBoost, LightGBM
  • pandas, numpy, matplotlib, seaborn
  • Optuna (hyperparameter tuning)

🚀 Purpose

This repository is a hands-on playground for practicing and validating machine learning workflows.
Each project includes steps like EDA, feature engineering, model training, evaluation, and iteration.

It serves as a learning record, with code structured for reusability and experimentation.


📌 Notes

  • Projects are standalone and modular.
  • Repo is continuously updated as new experiments are added.
  • Some models (e.g., SCU submissions) include day-by-day experiment tracking.
