This repo contains code velds encapsulating preprocessing for training of wordembeddings.

requirements

  • git
  • docker compose (note: older docker compose versions require running docker-compose instead of docker compose)

how to use

A code veld may be integrated into a chain veld, or used directly by adapting the configuration within its yaml file and using the template folders provided in this repo. Open the respective veld yaml file for more information.

Run a veld with:
