Looks Too Good To Be True: An Information-Theoretic Analysis of Hallucinations in Generative Restoration Models

no code implementations26 May 2024 Regev Cohen, Idan Kligvasser, Ehud Rivlin, Daniel Freedman

In this paper, we employ information-theory tools to investigate this phenomenon, revealing a fundamental tradeoff between uncertainty and perception.

Uncertainty-Aware PPG-2-ECG for Enhanced Cardiovascular Diagnosis using Diffusion Models

no code implementations19 May 2024 Omer Belhasin, Idan Kligvasser, George Leifman, Regev Cohen, Erin Rainaldi, Li-Fang Cheng, Nishant Verma, Paul Varghese, Ehud Rivlin, Michael Elad

Analyzing the cardiovascular system condition via Electrocardiography (ECG) is a common and highly effective approach, and it has been practiced and perfected over many decades.

Semi-supervised Quality Evaluation of Colonoscopy Procedures

no code implementations17 May 2023 Idan Kligvasser, George Leifman, Roman Goldenberg, Ehud Rivlin, Michael Elad

By integrating the local metric over the withdrawal phase, we build a global, offline quality metric, which is shown to be highly correlated to the standard Polyp Per Colonoscopy (PPC) quality metric.

Sparsity Aware Normalization for GANs

no code implementations3 Mar 2021 Idan Kligvasser, Tomer Michaeli

Generative adversarial networks (GANs) are known to benefit from regularization or normalization of their critic (discriminator) network during training.

Dense xUnit Networks

1 code implementation27 Nov 2018 Idan Kligvasser, Tomer Michaeli

For example, on ImageNet, our DxNet outperforms a ReLU-based DenseNet having 30% more parameters and achieves state-of-the-art results for this budget of parameters.

xUnit: Learning a Spatial Activation Function for Efficient Image Restoration

1 code implementation CVPR 2018 Idan Kligvasser, Tamar Rott Shaham, Tomer Michaeli

However, state-of-the-art results are typically achieved by very deep networks, which can reach tens of layers with tens of millions of parameters.
