This folder structure follows the convention of the cookiecutter datascience project. It is described as follows:
├── data
│ ├── external <- Data from third party sources.
│ ├── interim <- Intermediate data that has been transformed.
│ ├── processed <- The final, canonical data sets for modeling.
│ ├── raw <- The original, immutable data dump.
│ └── output <- The outputs of the models. Intended ONLY for bin/aip script to write in.
Data is also inmutable, and thus no need to track it. Thus, data folder is in .gitignore file.
