ML Pipeline for tabular data

Table of contents

Installation

    python3 -m venv env
    source env/bin/activate
    pip install poetry
    poetry install

Functionalities

This pipeline for tabular data offers the following functionalities:

  • automatic clean-up
  • splitting of dataset for any number of desired seeds or bootstraps
  • imputation of missing data and data normalisation
  • oversampling (if desired)
  • ability to run multiple feature selection strategies which can be configured step-by-step
  • verification of these strategies using one or more models
  • explainability

Configuration

Make sure to configure everything needed for your experiments in the config.yaml file.
Most important is the target_label, input_file and the label_as_index (if available).
Other noteworthy entries in the config file:

  • meta:
    • workers: set according to your machine
  • impute:
    • method: method to use for imputation of missing values
  • data_split:
    • n_seeds: number of data split seeds to run
    • test_frac: fraction of dataset to use for testing
  • selection:
    • scoring: the metric to use for training during selection and verification
    • jobs: each list defines a job of desired feature selection steps and normalisation
  • verification:
    • models: models to train and test
    • param_grids: parameter grids for GridSearchCV

Run

After the config file is set up properly, you can run the pipeline using:

python3 main.py

Computation progress is saved after each seed/bootstrap and will not be recomputed unless the meta.overwrite flag is set to True.
