SMRD: SURE-based Robust MRI Reconstruction with Diffusion Models

2 code implementations3 Oct 2023 Batu Ozturkler, Chao Liu, Benjamin Eckart, Morteza Mardani, Jiaming Song, Jan Kautz

However, diffusion models require careful tuning of inference hyperparameters on a validation set and are still sensitive to distribution shifts during testing.

ThinkSum: Probabilistic reasoning over sets using large language models

no code implementations4 Oct 2022 Batu Ozturkler, Nikolay Malkin, Zhen Wang, Nebojsa Jojic

Our results suggest that because the probabilistic inference in ThinkSum is performed outside of calls to the LLM, ThinkSum is less sensitive to prompt design, yields more interpretable predictions, and can be flexibly combined with latent variable models to extract structured knowledge from LLMs.

Unraveling Attention via Convex Duality: Analysis and Interpretations of Vision Transformers

no code implementations17 May 2022 Arda Sahiner, Tolga Ergen, Batu Ozturkler, John Pauly, Morteza Mardani, Mert Pilanci

Vision transformers using self-attention or its proposed alternatives have demonstrated promising results in many image related tasks.

Hidden Convexity of Wasserstein GANs: Interpretable Generative Models with Closed-Form Solutions

1 code implementation ICLR 2022 Arda Sahiner, Tolga Ergen, Batu Ozturkler, Burak Bartan, John Pauly, Morteza Mardani, Mert Pilanci

In this work, we analyze the training of Wasserstein GANs with two-layer neural network discriminators through the lens of convex duality, and for a variety of generators expose the conditions under which Wasserstein GANs can be solved exactly with convex optimization approaches, or can be represented as convex-concave games.
