Fused-Planes: Improving Planar Representations for Learning Large Sets of 3D Scenes

no code implementations31 Oct 2024 Karim Kassab, Antoine Schnepf, Jean-Yves Franceschi, Laurent Caraffa, Flavian vasile, Jeremie Mary, Andrew Comport, Valérie Gouet-Brunet

In this paper, we introduce Fused-Planes, a new planar architecture that improves Tri-Planes resource-efficiency in the framework of learning large sets of scenes, which we call "multi-scene inverse graphics".

Bringing NeRFs to the Latent Space: Inverse Graphics Autoencoder

no code implementations30 Oct 2024 Antoine Schnepf, Karim Kassab, Jean-Yves Franceschi, Laurent Caraffa, Flavian vasile, Jeremie Mary, Andrew Comport, Valerie Gouet-Brunet

To this end, we regularize an image autoencoder with 3D-geometry by aligning its latent space with jointly trained latent 3D scenes.

Improving Consistency Models with Generator-Induced Flows

1 code implementation13 Jun 2024 Thibaut Issenhuth, Sangchul Lee, Ludovic Dos Santos, Jean-Yves Franceschi, Chansoo Kim, Alain Rakotomamonjy

The former relies on the true velocity field of the corresponding differential equation, approximated by a pre-trained neural network.

Differentially Private Gradient Flow based on the Sliced Wasserstein Distance

1 code implementation13 Dec 2023 Ilana Sebag, Muni Sreenivas Pydi, Jean-Yves Franceschi, Alain Rakotomamonjy, Mike Gartrell, Jamal Atif, Alexandre Allauzen

In this paper, we introduce a novel differentially private generative modeling approach based on a gradient flow in the space of probability measures.

Unifying GANs and Score-Based Diffusion as Generative Particle Models

1 code implementation NeurIPS 2023 Jean-Yves Franceschi, Mike Gartrell, Ludovic Dos Santos, Thibaut Issenhuth, Emmanuel de Bézenac, Mickaël Chen, Alain Rakotomamonjy

Particle-based deep generative models, such as gradient flows and score-based diffusion models, have recently gained traction thanks to their striking performance.

Continuous PDE Dynamics Forecasting with Implicit Neural Representations

1 code implementation29 Sep 2022 Yuan Yin, Matthieu Kirchmeyer, Jean-Yves Franceschi, Alain Rakotomamonjy, Patrick Gallinari

Effective data-driven PDE forecasting methods often rely on fixed spatial and / or temporal discretizations.

A Neural Tangent Kernel Perspective of GANs

1 code implementation10 Jun 2021 Jean-Yves Franceschi, Emmanuel de Bézenac, Ibrahim Ayed, Mickaël Chen, Sylvain Lamprier, Patrick Gallinari

We propose a novel theoretical framework of analysis for Generative Adversarial Networks (GANs).

PDE-Driven Spatiotemporal Disentanglement

1 code implementation ICLR 2021 Jérémie Donà, Jean-Yves Franceschi, Sylvain Lamprier, Patrick Gallinari

A recent line of work in the machine learning community addresses the problem of predicting high-dimensional spatiotemporal phenomena by leveraging specific tools from the differential equations theory.

Unsupervised Scalable Representation Learning for Multivariate Time Series

1 code implementation NeurIPS 2019 Jean-Yves Franceschi, Aymeric Dieuleveut, Martin Jaggi

Time series constitute a challenging data type for machine learning algorithms, due to their highly variable lengths and sparse labeling in practice.
