CIGMA: Causal Information-Gain Mechanistic Attribution of Attention Heads in Vision Transformers

CVPR 2026

Vision Transformers often rely on spurious background correlations rather than foreground object features. While prior model pruning approaches focus solely on improving accuracy, they lack interpretability and fail to verify whether predictions are actually made by focusing on the main foreground o

Conditional Prior-based Non-stationary Channel Estimation Using Accelerated Diffusion Models

ICASSP 2026poster

Wireless channels in motion-rich urban microcell (UMi) settings are non-stationary; mobility and scatterer dynamics shift the distribution over time, degrading classical and deep estimators. This work proposes conditional prior diffusion for channel estimation, which learns a history-conditioned sco…
