    • Read existing literature, performed original research on visualizing & interpreting Transformer vision models • Collaborated in team of 3 applying existing and original models, wrote paper and presented to 90+ people • Prior to our work, there had been no applications of SHAP to transformer-based image classifiers • Used PyTorch to train 3 powerful models on dataset of 60k images, all obtained high accuracies (90%+) • To interpret those models, we trained _surrogates_ on those models, also obtaining high accuracies (~90%) • Demonstrated FastSHAP's usefulness for the first time on transformer-based image classifiers
