Diffusion Models Beat GANs on Image Classification

1 code implementation17 Jul 2023 Soumik Mukhopadhyay, Matthew Gwilliam, Vatsal Agarwal, Namitha Padmanabhan, Archana Swaminathan, Srinidhi Hegde, Tianyi Zhou, Abhinav Shrivastava

We explore optimal methods for extracting and using these embeddings for classification tasks, demonstrating promising results on the ImageNet classification task.

A Frequency Perspective of Adversarial Robustness

no code implementations26 Oct 2021 Shishira R Maiya, Max Ehrlich, Vatsal Agarwal, Ser-Nam Lim, Tom Goldstein, Abhinav Shrivastava

Our analysis shows that adversarial examples are neither in high-frequency nor in low-frequency components, but are simply dataset dependent.

Weakly Supervised Lesion Co-segmentation on CT Scans

no code implementations24 Jan 2020 Vatsal Agarwal, You-Bao Tang, Jing Xiao, Ronald M. Summers

In this work, we propose a weakly-supervised co-segmentation model that first generates pseudo-masks from the RECIST slices and uses these as training labels for an attention-based convolutional neural network capable of segmenting common lesions from a pair of CT scans.

Weakly-Supervised Lesion Segmentation on CT Scans using Co-Segmentation

no code implementations23 Jan 2020 Vatsal Agarwal, You-Bao Tang, Jing Xiao, Ronald M. Summers

Lesion segmentation on computed tomography (CT) scans is an important step for precisely monitoring changes in lesion/tumor growth.
