Mesh Neural Cellular Automata

no code implementations6 Nov 2023 Ehsan Pajouheshgar, Yitao Xu, Alexander Mordvintsev, Eyvind Niklasson, Tong Zhang, Sabine Süsstrunk

We propose Mesh Neural Cellular Automata (MeshNCA), a method for directly synthesizing dynamic textures on 3D meshes without requiring any UV maps.

Differentiable Programming of Chemical Reaction Networks

no code implementations6 Feb 2023 Alexander Mordvintsev, Ettore Randazzo, Eyvind Niklasson

We present a differentiable formulation of abstract chemical reaction networks (CRNs) that can be trained to solve a variety of computational tasks.

Transformers learn in-context by gradient descent

1 code implementation15 Dec 2022 Johannes von Oswald, Eyvind Niklasson, Ettore Randazzo, João Sacramento, Alexander Mordvintsev, Andrey Zhmoginov, Max Vladymyrov

We start by providing a simple weight construction that shows the equivalence of data transformations induced by 1) a single linear self-attention layer and by 2) gradient-descent (GD) on a regression loss.

Differentiable Programming of Reaction-Diffusion Patterns

no code implementations22 Jun 2021 Alexander Mordvintsev, Ettore Randazzo, Eyvind Niklasson

Reaction-Diffusion (RD) systems provide a computational framework that governs many pattern formation processes in nature.

Texture Generation with Neural Cellular Automata

3 code implementations15 May 2021 Alexander Mordvintsev, Eyvind Niklasson, Ettore Randazzo

Neural Cellular Automata (NCA) have shown a remarkable ability to learn the required rules to "grow" images, classify morphologies, segment images, as well as to do general computation such as path-finding.

MPLP: Learning a Message Passing Learning Protocol

2 code implementations2 Jul 2020 Ettore Randazzo, Eyvind Niklasson, Alexander Mordvintsev

We present a novel method for learning the weights of an artificial neural network - a Message Passing Learning Protocol (MPLP).

Learning to Map Natural Language Instructions to Physical Quadcopter Control using Simulated Flight

1 code implementation21 Oct 2019 Valts Blukis, Yannick Terme, Eyvind Niklasson, Ross A. Knepper, Yoav Artzi

Learning uses both simulation and real environments without requiring autonomous flight in the physical environment during training, and combines supervised learning for predicting positions to visit and reinforcement learning for continuous control.
