New method visualizes feature evolution in Vision Transformers

Researchers have developed a new method to visualize the training process of Vision Transformers (ViTs) by examining feature evolution across network depth and training time. Using Sparse Autoencoders (SAEs), they can identify and track features as they emerge and change layers during training. This analysis reveals that feature migration, the shift in a feature's most detectable layer, primarily occurs early in training and tends to move towards earlier layers, with deeper layers stabilizing sooner than shallower ones.
