# emotion_classification

This model is a fine-tuned version of [google/paligemma-3b-pt-224](https://huggingface.co/google/paligemma-3b-pt-224) on the [FastJobs/Visual_Emotional_Analysis](https://huggingface.co/datasets/FastJobs/Visual_Emotional_Analysis) dataset.

## Training Data

This model was trained on the [FastJobs/Visual_Emotional_Analysis](https://huggingface.co/datasets/FastJobs/Visual_Emotional_Analysis) dataset. 

The dataset contains:
- **800 images** annotated with **8 emotion labels**:
  - Anger
  - Contempt
  - Disgust
  - Fear
  - Happy
  - Neutral
  - Sad
  - Surprise

## Intended uses & limitations

### Intended Uses
- Emotion classification from visual inputs (images).

### Limitations
- May reflect biases from the training dataset.
- Performance may degrade in domains outside the training data.
- Not suitable for critical or sensitive decision-making tasks.

##  How to use this model
```python
from transformers import (PaliGemmaProcessor,PaliGemmaForConditionalGeneration,)
from transformers.image_utils import load_image
import torch
from transformers import BitsAndBytesConfig
from peft import get_peft_model
from huggingface_hub import login
from PIL import Image
login(api_key)

device = "cuda" if torch.cuda.is_available() else "CPU"

bnb_config = BitsAndBytesConfig(
        load_in_4bit=True,
        bnb_4bit_quant_type="nf4",
        bnb_4bit_compute_type=torch.bfloat16
)

# Load base model
model_id = "google/paligemma-3b-pt-224"
model = PaliGemmaForConditionalGeneration.from_pretrained(model_id, quantization_config=bnb_config, device_map="auto")
processor = PaliGemmaProcessor.from_pretrained(model_id)

# Load adapter
adapter_path = "digo-prayudha/emotion_classification" 
model = PeftModel.from_pretrained(model, adapter_path)

image = Image.open("image.jpg").convert("RGB")

prompt = (
    "Classify the emotion expressed in this image."
)

inputs = processor(
    text=prompt,
    images=image,
    return_tensors="pt",
    padding="longest",
    tokenize_newline_separately=False
).to(model.device)

model.eval() 
with torch.no_grad():
    outputs = model.generate(**inputs)

decoded_output = processor.decode(outputs[0], skip_special_tokens=True)

print("Predicted Emotion:", decoded_output)
```
