C3: High-performance and low-complexity neural compression from a single image or video

no code implementations5 Dec 2023 Hyunjik Kim, Matthias Bauer, Lucas Theis, Jonathan Richard Schwarz, Emilien Dupont

On the UVG video benchmark, we match the RD performance of the Video Compression Transformer (Mentzer et al.), a well-established neural video codec, with less than 5k MACs/pixel for decoding.

Spatial Functa: Scaling Functa to ImageNet Classification and Generation

no code implementations6 Feb 2023 Matthias Bauer, Emilien Dupont, Andy Brock, Dan Rosenbaum, Jonathan Richard Schwarz, Hyunjik Kim

Neural fields, also known as implicit neural representations, have emerged as a powerful means to represent complex signals of various modalities.

COIN++: Neural Compression Across Modalities

1 code implementation30 Jan 2022 Emilien Dupont, Hrushikesh Loya, Milad Alizadeh, Adam Goliński, Yee Whye Teh, Arnaud Doucet

Neural compression algorithms are typically based on autoencoders that require specialized encoder and decoder architectures for different data modalities.

From data to functa: Your data point is a function and you can treat it like one

1 code implementation28 Jan 2022 Emilien Dupont, Hyunjik Kim, S. M. Ali Eslami, Danilo Rezende, Dan Rosenbaum

A powerful continuous alternative is then to represent these measurements using an implicit neural representation, a neural function trained to output the appropriate measurement value for any input spatial location.

COIN: COmpression with Implicit Neural representations

1 code implementation ICLR Workshop Neural_Compression 2021 Emilien Dupont, Adam Goliński, Milad Alizadeh, Yee Whye Teh, Arnaud Doucet

We propose a new simple approach for image compression: instead of storing the RGB values for each pixel of an image, we store the weights of a neural network overfitted to the image.

Generative Models as Distributions of Functions

1 code implementation9 Feb 2021 Emilien Dupont, Yee Whye Teh, Arnaud Doucet

By treating data points as functions, we can abstract away from the specific type of data we train on and construct models that are agnostic to discretization.

LieTransformer: Equivariant self-attention for Lie Groups

1 code implementation20 Dec 2020 Michael Hutchinson, Charline Le Lan, Sheheryar Zaidi, Emilien Dupont, Yee Whye Teh, Hyunjik Kim

Group equivariant neural networks are used as building blocks of group invariant neural networks, which have been shown to improve generalisation performance and data efficiency through principled parameter sharing.

Equivariant Neural Rendering

1 code implementation ICML 2020 Emilien Dupont, Miguel Angel Bautista, Alex Colburn, Aditya Sankar, Carlos Guestrin, Josh Susskind, Qi Shan

We propose a framework for learning neural scene representations directly from images, without 3D supervision.

Augmented Neural ODEs

6 code implementations NeurIPS 2019 Emilien Dupont, Arnaud Doucet, Yee Whye Teh

We show that Neural Ordinary Differential Equations (ODEs) learn representations that preserve the topology of the input space and prove that this implies the existence of functions Neural ODEs cannot represent.

Probabilistic Semantic Inpainting with Pixel Constrained CNNs

2 code implementations8 Oct 2018 Emilien Dupont, Suhas Suresha

Semantic inpainting is the task of inferring missing pixels in an image given surrounding pixels and high level image semantics.

Learning Disentangled Joint Continuous and Discrete Representations

4 code implementations NeurIPS 2018 Emilien Dupont

We present a framework for learning disentangled and interpretable jointly continuous and discrete representations in an unsupervised manner.

Generating Realistic Geology Conditioned on Physical Measurements with Generative Adversarial Networks

1 code implementation8 Feb 2018 Emilien Dupont, Tuanfeng Zhang, Peter Tilke, Lin Liang, William Bailey

An important problem in geostatistics is to build models of the subsurface of the Earth given physical measurements at sparse spatial locations.
