Vision Transformer (ViT) for Facial Expression Recognition Model Card

Model Overview

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 FER2013 and MMI facial Expression datasets , which consist of facial images categorized into seven different emotions:

  • Angry
  • Disgust
  • Fear
  • Happy
  • Sad
  • Surprise
  • Neutral

Data Preprocessing

The input images are preprocessed before being fed into the model. The preprocessing steps include:

  • Resizing: Images are resized to the specified input size.
  • Normalization: Pixel values are normalized to a specific range.
  • Data Augmentation: Random transformations such as rotations, flips, and zooms are applied to augment the training dataset.
