DDNeRF: Depth Distribution Neural Radiance Fields

1 code implementation30 Mar 2022 David Dadon, Ohad Fried, Yacov Hel-Or

We present depth distribution neural radiance field (DDNeRF), a new method that significantly increases sampling efficiency along rays during training while achieving superior results for a given sampling budget.

DeepShadow: Neural Shape from Shadow

1 code implementation28 Mar 2022 Asaf Karnieli, Ohad Fried, Yacov Hel-Or

We show that the self and cast shadows not only do not disturb 3D reconstruction, but can be used alone, as a strong learning signal, to recover the depth map and surface normals.

Pairwise Margin Maximization for Deep Neural Networks

1 code implementation9 Oct 2021 Berry Weinstein, Shai Fine, Yacov Hel-Or

The weight decay regularization term is widely used during training to constrain expressivity, avoid overfitting, and improve generalization.

Margin-Based Regularization and Selective Sampling in Deep Neural Networks

no code implementations13 Sep 2020 Berry Weinstein, Shai Fine, Yacov Hel-Or

We derive a new margin-based regularization formulation, termed multi-margin regularization (MMR), for deep neural networks (DNNs).

Autoencoder Image Interpolation by Shaping the Latent Space

no code implementations4 Aug 2020 Alon Oring, Zohar Yakhini, Yacov Hel-Or

We argue that these incongruities are due to the structure of the latent space and because such naively interpolated latent vectors deviate from the data manifold.

Proximity Preserving Binary Code using Signed Graph-Cut

no code implementations5 Feb 2020 Inbal Lav, Shai Avidan, Yoram Singer, Yacov Hel-Or

We show that the proposed approximation is superior to the commonly used spectral methods with respect to both accuracy and complexity.

Selective sampling for accelerating training of deep neural networks

1 code implementation16 Nov 2019 Berry Weinstein, Shai Fine, Yacov Hel-Or

We present a selective sampling method designed to accelerate the training of deep neural networks.

The Generalized Laplacian Distance and Its Applications for Visual Matching

no code implementations CVPR 2013 Elhanan Elboer, Michael Werman, Yacov Hel-Or

The graph Laplacian operator, which originated in spectral graph theory, is commonly used for learning applications such as spectral clustering and embedding.
