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 microsoft/resnet-50 DINO checkpoint.

How to Get Started with the Model

Use the code below to get started with the model.

Click to expand
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('microsoft/resnet-50')
model = AutoModel.from_pretrained('microsoft/resnet-50').eval().to(device)

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

with open('emb-gam-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(7*7, 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()

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
