AffectNet is a large-scale database of facial expressions in the wild, containing more than 1M facial images from the Internet. This model was fine-tuned on a subset of the manually annotated images covering 7 basic emotions (excluding Contempt to align with the base model's taxonomy).

Usage

Architecture: Vision Transformer (ViT)
Task: Facial Emotion Recognition
Emotions: Anger, Disgust, Fear, Happiness, Neutral, Sadness, Surprise
