Usage

python

from huggingface_hub import hf_hub_download
from transformers import AutoTokenizer, AutoProcessor, SiglipModel
import torch
from PIL import Image
import json
from model_arch import MultimodalClassifier

# Download model and config from Hugging Face
repo_id = "manavbangotra/sinc-v1-siglip2-kee-speed-small"  # Replace with your repo
model_path = hf_hub_download(repo_id=repo_id, filename="best_multimodal.pt")
config_path = hf_hub_download(repo_id=repo_id, filename="config.json")

# Load configuration
with open(config_path) as f:
    config = json.load(f)

labels = config["labels"]
num_labels = config["num_labels"]

# Load model components
tokenizer = AutoTokenizer.from_pretrained("microsoft/deberta-v3-small")
processor = AutoProcessor.from_pretrained("google/siglip2-base-patch16-256")
clip_model = SiglipModel.from_pretrained("google/siglip2-base-patch16-256")

model = MultimodalClassifier("microsoft/deberta-v3-small", clip_model, num_labels, text_finetune=True, clip_finetune=False)
#Use cuda if available
model.load_state_dict(torch.load(model_path, map_location="cpu"))

# Example usage
text = "Elegant summer dress with floral pattern"
image = Image.open("product_image.jpg")

text_inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True, max_length=64)
image_inputs = processor(images=image, return_tensors="pt")

# Predict
with torch.no_grad():
    outputs = model(
        input_ids=text_inputs["input_ids"],
        attention_mask=text_inputs["attention_mask"],
        pixel_values=image_inputs["pixel_values"]
    )
    predictions = torch.softmax(outputs["logits"], dim=-1)
    predicted_class = torch.argmax(predictions, dim=-1).item()
    confidence = predictions[0][predicted_class].item()

print(f"Predicted: {labels[predicted_class]} ({confidence:.2%})")

Training Details

Training Data: E-commerce product dataset with titles and images
Training Strategy: Fine-tuned text encoder, frozen image encoder
Optimizer: AdamW with linear warmup scheduler
Batch Size: 8
Learning Rate: 2e-5
Epochs: 3
Max Text Length: 64 tokens

Limitations

Performance varies across categories (especially small classes)
