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 [`google/vit-base-patch16-224` ViT checkpoint](https://huggingface.co/google/vit-base-patch16-224). ## Intended uses & limitations This model is not intended to be used in production. ## Training Procedure ### Hyperparameters The model is trained with below hyperparameters.
