• The directory structure of all competitions follows:

Dacon-competition/
├── Competition_code.ipynb
├── submissions.csv
└── /dataset
    ├── train.csv
    ├── test.csv
    ├── sample_submission.csv

• train.csv is the training data and test.csv is the test data. And neither can be shared due to data security.
• We make submissions.csv using test.csv.
• All ipynb notebooks are created in the Colab environment.
• Leaderboard : private score rank/number of all participants
