# Model Card for Model ID (Use this model for Leaderboard)

This is a fine-tuned Vision Transformer (ViT) model from Google. The model was loaded and fine-tuned on the training data collected. 
Compared to Attempt 1, we are using the expanded dataset, trained for 20 epochs instead of 5, and only updated the classifier parameters at training time.
Compared to Attempt 3, this was trained for 20 epochs and had a learning rate of
