Practical overview
When it fits
Use it when you have a Python/PyTorch research workflow and want code for training concept-based models or investigating interventions, rather than a hosted prediction service.
Who it is for
- Machine-learning researchers studying concept-based interpretability
- Python developers building research prototypes with task and concept annotations
Documented uses
- Train a concept embedding model on task-labelled samples with binary concept annotations
- Explore test-time concept interventions on model predictions
- Investigate intervention-aware training and concept-selection policies
- Study concept interventions under distribution shifts using the repository’s research implementations
Requirements & limits
The repository is public on GitHub and licensed under MIT. The README specifies Python 3.7 or later.
- The documented training workflow requires task-labelled samples and binary concept annotations.
- Users need to provide dataset objects and an appropriate concept extractor architecture.
- The README lists dependencies in
requirements.txtand shows a PyTorch Lightning trainer using either GPU or CPU.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install the Python package
Clone the repository, install its package, and import it locally.
Before you start
- Python 3.7 or later
- Git and a local Python environment
Steps
Clone the repository with the command below.
git clone https://github.com/mateoespinosa/cemChange into the cloned
cemdirectory.Run the command below.
python setup.py installImport the installed package with
import cem.
Expected outcome
The `cem` package is installed locally and can be imported from Python.
Guide limitations
- Training requires installing the code requirements listed in
requirements.txt. - Installation instructions do not establish that a particular environment or dependency set is compatible.
Prepare a CEM training workflow
Set up the documented model and trainer pattern for training a CEM on annotated samples.
Before you start
- The package installed and its requirements installed
- PyTorch dataset objects for training and validation, with samples annotated for a downstream task and binary concepts
- A suitable concept extractor architecture
Steps
Import PyTorch Lightning and
ConceptEmbeddingModelfromcem.models.cem.Provide training and validation dataset objects.
Construct
ConceptEmbeddingModelwith the concept and task counts, model settings, and concept extractor.Configure a PyTorch Lightning trainer and call
trainer.fit(cem_model, train_dl, val_dl).
Expected outcome
A CEM training workflow is configured to fit the model on the supplied training and validation data.
Guide limitations
- The README uses placeholders for datasets and the concept extractor; these must be supplied for the intended task.
- The example does not provide a dataset, model architecture, or results for a particular application.
