Locality-Attending Vision Transformer

Sina Hajimiri, Farzad Beizaee, Fereshteh Shakeri +3

Vision transformers have demonstrated remarkable success in classification by leveraging global self-attention to capture long-range dependencies. However, this same mechanism can…

OCTOPUS: Enhancing the Spatial-Awareness of Vision SSMs with Multi-Dimensional Scans and Traversal Selection

Kunal Mahatha, Ali Bahri, Pierre Marza +5

State space models (SSMs) have recently emerged as an alternative to transformers due to their unique ability of modeling global relationships in text with linear complexity. Howev…

SPARK: Stochastic Propagation via Affinity-guided Random walK for training-free unsupervised segmentation

Kunal Mahatha, Jose Dolz, Christian Desrosiers

We argue that existing training-free segmentation methods rely on an implicit and limiting assumption, that segmentation is a spectral graph partitioning problem over diffusion-der…

Histopath-C: Towards Realistic Domain Shifts for Histopathology Vision-Language Adaptation

Mehrdad Noori, Gustavo Adolfo Vargas Hakim, David Osowiechi +6

Medical Vision-language models (VLMs) have shown remarkable performances in various medical imaging domains such as histo\-pathology by leveraging pre-trained, contrastive models t…

Purge-Gate: Backpropagation-Free Test-Time Adaptation for Point Clouds Classification via Token Purging

Moslem Yazdanpanah, Ali Bahri, Mehrdad Noori +5

Test-time adaptation (TTA) is crucial for mitigating performance degradation caused by distribution shifts in 3D point cloud classification. In this work, we introduce Token Purgin…
