Model description

This model is a fine-tuned version of google/paligemma-3b-pt-224 on the AffectNet dataset. The model aims to classify the emotion of face image or image with one person into eight categoris such as 'neutral', 'happy', 'sad', 'surprise', 'fear', 'disgust', 'anger', 'contempt'

Model Performance

Accuracy: 59.4 %, F1 score: 59 %
