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 facebook/dino-vitb16 DINO checkpoint.

How to Get Started with the Model

Use the code below to get started with the model.

<details> <summary> Click to expand </summary>

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('facebook/dino-vitb16')
model = AutoModel.from_pretrained('facebook/dino-vitb16').eval().to(device)

# load logistic regression
os.mkdir('emb-gam-dino')
hub_utils.download(repo_id='Ramos-Ramos/emb-gam-dino', dst='emb-gam-dino')

with open('emb-gam-dino/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, 1:].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()
