Organization

The main resuable code is in the src folder. The code for our different research streams is in the projects folder. Other folders may include:

• data: contains data used in the experiments.
• models: saves models' weights.
• launchers: contains bash scripts to launch experiments.
• notebooks: used for exploration and visualization.
• scripts: contains python scripts to run experiments.
• tests: contains tests for the code.
• tutorial: contains tutorial notebooks to get started with LLMs' training.
