# Model description
This is a LogisticRegressionCV model trained on averages of patch embeddings from the Imagenette dataset. This forms the GAM of an [Emb-GAM](https://arxiv.org/abs/2209.11799) extended to images. Patch embeddings are meant to be extracted with the [`facebook/dino-vitb16` DINO checkpoint](https://huggingface.co/facebook/dino-vitb16).
## Intended uses & limitations
This model is not intended to be used in production.
