ViewFusion: Learning Composable Diffusion Models for Novel View Synthesis

1 code implementation5 Feb 2024 Bernard Spiegl, Andrea Perin, Stéphane Deny, Alexander Ilin

Deep learning is providing a wealth of new approaches to the old problem of novel view synthesis, from Neural Radiance Field (NeRF) based approaches to end-to-end style architectures.

On the special role of class-selective neurons in early training

no code implementations27 May 2023 Omkar Ranadive, Nikhil Thakurdesai, Ari S Morcos, Matthew Leavitt, Stéphane Deny

Finally, in causal experiments where we regularize against class selectivity at different points in training, we show that the presence of class-selective neurons early in training is critical to the successful training of the network; in contrast, class-selective neurons can be suppressed later in training with little effect on final accuracy.

Progress and limitations of deep networks to recognize objects in unusual poses

1 code implementation16 Jul 2022 Amro Abbas, Stéphane Deny

We show that classifying these images is still a challenge for all networks tested, with an average accuracy drop of 29. 5% compared to when the objects are presented upright.

Barlow Twins: Self-Supervised Learning via Redundancy Reduction

24 code implementations4 Mar 2021 Jure Zbontar, Li Jing, Ishan Misra, Yann Lecun, Stéphane Deny

This causes the embedding vectors of distorted versions of a sample to be similar, while minimizing the redundancy between the components of these vectors.

Addressing the Topological Defects of Disentanglement via Distributed Operators

1 code implementation10 Feb 2021 Diane Bouchacourt, Mark Ibrahim, Stéphane Deny

A core challenge in Machine Learning is to learn to disentangle natural factors of variation in data (e. g. object shape vs. pose).
