The dataset used is a preprocessed MNIST file containing group-equivariant transformations. It is stored as a pickle file:
Path: data/P4MUPDATED.pkl
Structure:
images: Transformed MNIST image data
labels: Corresponding labels
š Note: To avoid misclassification due to symmetry ambiguity, only translation transformations were applied to digits 6 and 9. All other digits were transformed using both dihedral (D4) and cyclic group symmetries.
