get_started_code

from PIL import Image from skops import hub_utils import torch from transformers import AutoFeatureExtractor, AutoModel import pickle import os

load embedding model

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu') feature_extractor = AutoFeatureExtractor.from_pretrained('Ramos-Ramos/vicreg-resnet-50') model = AutoModel.from_pretrained('Ramos-Ramos/vicreg-resnet-50').eval().to(device)

load logistic regression

os.mkdir('emb-gam-vicreg-resnet') hub_utils.download(repo_id='Ramos-Ramos/emb-gam-vicreg-resnet', dst='emb-gam-vicreg-resnet')

with open('emb-gam-vicreg-resnet/model.pkl', 'rb') as file: logistic_regression = pickle.load(file)

load image

img = Image.open('examples/english_springer.png')

preprocess image

inputs = {k: v.to(device) for k, v in feature_extractor(img, return_tensors='pt').items()}

extract patch embeddings

with torch.no_grad(): patch_embeddings = model(*inputs).last_hidden_state[0].permute(1, 2, 0).view(77, 2048).cpu()

classify

pred = logistic_regression.predict(patch_embeddings.sum(dim=0, keepdim=True))

get patch contributions

patch_contributions = logistic_regression.coef_ @ patch_embeddings.T.numpy()

limitations

This model is not intended to be used in production.

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 extended to images. Patch embeddings are meant to be extracted with the Ramos-Ramos/vicreg-resnet-50 ResNet checkpoint.

eval_method

The model is evaluated using test split, on accuracy and F1 score with macro average.
