Multi-Set Inoculation: Assessing Model Robustness Across Multiple Challenge Sets

no code implementations15 Nov 2023 Vatsal Gupta, Pranshu Pandya, Tushar Kataria, Vivek Gupta, Dan Roth

Language models, given their black-box nature, often exhibit sensitivity to input perturbations, leading to trust issues due to hallucinations.

Structural Cycle GAN for Virtual Immunohistochemistry Staining of Gland Markers in the Colon

no code implementations25 Aug 2023 Shikha Dubey, Tushar Kataria, Beatrice Knudsen, Shireen Y. Elhabian

Quantitative metrics such as FID and SSIM are frequently used for the analysis of generative models, but they do not correlate explicitly with higher-quality virtual staining results.

To pretrain or not to pretrain? A case study of domain-specific pretraining for semantic segmentation in histopathology

1 code implementation6 Jul 2023 Tushar Kataria, Beatrice Knudsen, Shireen Elhabian

In this study, we compare the performance of gland and cell segmentation tasks with histopathology domain-specific and non-domain-specific (real-world images) pretrained weights.

ADASSM: Adversarial Data Augmentation in Statistical Shape Models From Images

no code implementations6 Jul 2023 Mokshagna Sai Teja Karanam, Tushar Kataria, Krithika Iyer, Shireen Elhabian

However, these augmentation methods focus on shape augmentation, whereas deep learning models exhibit image-based texture bias resulting in sub-optimal models.

InfoSync: Information Synchronization across Multilingual Semi-structured Tables

no code implementations6 Jul 2023 Siddharth Khincha, Chelsi Jain, Vivek Gupta, Tushar Kataria, Shuo Zhang

The proposed method includes 1) Information Alignment to map rows and 2) Information Update for updating missing/outdated information for aligned tables across multilingual tables.

Unsupervised Domain Adaptation for Medical Image Segmentation via Feature-space Density Matching

no code implementations9 May 2023 Tushar Kataria, Beatrice Knudsen, Shireen Elhabian

Nonetheless, they often fail to generalize when there is a significant domain (i. e., distributional) shift between the training (i. e., source) data and the dataset(s) encountered when deployed (i. e., target), necessitating manual annotations for the target data to achieve acceptable performance.
