Vision Mamba vs. Gated CNN: Decoding Representation Differences

Researchers have investigated the distinct representation strategies employed by Vision Mamba (VMamba) and Gated CNN models, particularly in high-resolution vision tasks. Through cross-model centered kernel alignment (CKA) analysis, they found that VMamba's final stage blocks create representations that differ from MambaOut and its own preceding blocks. VMamba organizes semantic evidence across token magnitude and direction, showing an advantage in dense prediction tasks like semantic segmentation, while MambaOut relies on sparse, dominant tokens.
