Revisiting Sanity Checks for Saliency Maps

no code implementations27 Oct 2021 Gal Yona, Daniel Greenfeld

They argue that some popular saliency methods should not be used for explainability purposes since the maps they produce are not sensitive to the underlying model that is to be explained.

On Calibration and Out-of-domain Generalization

no code implementations NeurIPS 2021 Yoav Wald, Amir Feder, Daniel Greenfeld, Uri Shalit

In this work, we draw a link between OOD performance and model calibration, arguing that calibration across multiple domains can be viewed as a special case of an invariant representation leading to better OOD generalization.

Robust Learning with the Hilbert-Schmidt Independence Criterion

1 code implementation ICML 2020 Daniel Greenfeld, Uri Shalit

We adapt it to the task of learning for unsupervised covariate shift: learning on a source domain without access to any instances or labels from the unknown target domain, but with the assumption that $p(y|x)$ (the conditional probability of labels given instances) remains the same in the target domain.

Learning to Optimize Multigrid PDE Solvers

1 code implementation25 Feb 2019 Daniel Greenfeld, Meirav Galun, Ron Kimmel, Irad Yavneh, Ronen Basri

Constructing fast numerical solvers for partial differential equations (PDEs) is crucial for many scientific disciplines.

Improved Training for Self-Training by Confidence Assessments

no code implementations30 Sep 2017 Gal Hyams, Daniel Greenfeld, Dor Bank

Our suggested approaches were applied on the MNIST data-set as a proof of concept for a vision classification task and on the ADE20K data-set in order to tackle the semi-supervised semantic segmentation problem.
