Tiny on-surface point perturbations trigger a bifurcation in the reverse diffusion process of 3D transformers, localized to a low-rank cross-attention write that can be reshaped at test time to suppress the failure.

Meltdown: Circuits and Bifurcations in Point-Cloud-Conditioned 3D Diffusion Transformers
Tiny on-surface point perturbations trigger a bifurcation in the reverse diffusion process of 3D transformers, localized to a low-rank cross-attention write that can be reshaped at test time to suppress the failure.
