# Facial-Expression-Recognition
This model is a fine-tuned version of google/vit-base-patch16-224-in21k on the FER 2013 and AffectNet dataset datasets. It achieves the following results on the evaluation set:
Accuracy - 0.922
Loss - 0.213
### Model Description
The vit-face-expression model is a Vision Transformer fine-tuned for the task of facial emotion recognition.
It is trained on the FER2013and AffectNet datasets, which consist of facial images categorized into eight different emotions:
-anger
-contempt
-sad
-happy
-neutral
-disgust
-fear
-surprise
## Model Details
The model has been fine-tuned using the following hyperparameters:
| Hyperparameter | Value |
|-------------------------|------------|
| Train Batch Size | 32 |
| Eval Batch Size | 64 |
| Learning Rate | 2e-4 |
| Gradient Accumulation | 2 |
| LR Scheduler | Linear |
| Warmup Ratio | 0.04 |
| Num Epochs | 10 |
## How to Get Started with the Model
Example usage:
```python
from transformers import AutoImageProcessor, AutoModelForImageClassification, pipeline
pipe = pipeline("image-classification", model="HardlyHumans/Facial-expression-detection")
processor = AutoImageProcessor.from_pretrained("HardlyHumans/Facial-expression-detection")
model = AutoModelForImageClassification.from_pretrained("HardlyHumans/Facial-expression-detection")
labels = model.config.id2label
outputs = model(**inputs)
logits = outputs.logits
predicted_class_idx = logits.argmax(-1).item()
predicted_label = labels[predicted_class_idx]
```
## Environmental Impact
The net estimated CO2 emission using the [Machine Learning Impact calculator](https://mlco2.github.io/impact#compute) scale is around 8.82kg of CO2.
