D-Flow: Differentiating through Flows for Controlled Generation

no code implementations21 Feb 2024 Heli Ben-Hamu, Omri Puny, Itai Gat, Brian Karrer, Uriel Singer, Yaron Lipman

Taming the generation outcome of state of the art Diffusion and Flow-Matching (FM) models without having to re-train a task-specific model unlocks a powerful tool for solving inverse problems, conditional generation, and controlled generation in general.

Mosaic-SDF for 3D Generative Models

no code implementations14 Dec 2023 Lior Yariv, Omri Puny, Natalia Neverova, Oran Gafni, Yaron Lipman

Current diffusion or flow-based generative models for 3D shapes divide to two: distilling pre-trained 2D image diffusion models, and training directly on 3D shapes.

Equivariant Polynomials for Graph Neural Networks

no code implementations22 Feb 2023 Omri Puny, Derek Lim, Bobak T. Kiani, Haggai Maron, Yaron Lipman

This paper introduces an alternative expressive power hierarchy based on the ability of GNNs to calculate equivariant polynomials of a certain degree.

Global Attention Improves Graph Networks Generalization

3 code implementations14 Jun 2020 Omri Puny, Heli Ben-Hamu, Yaron Lipman

This paper advocates incorporating a Low-Rank Global Attention (LRGA) module, a computation and memory efficient variant of the dot-product attention (Vaswani et al., 2017), to Graph Neural Networks (GNNs) for improving their generalization power.
