Biomaker CA: a Biome Maker project using Cellular Automata

no code implementations18 Jul 2023 Ettore Randazzo, Alexander Mordvintsev

Finally, we show how to perform interactive evolution, where the user decides how to evolve a plant model interactively and then deploys it in a larger environment.

Growing Steerable Neural Cellular Automata

2 code implementations19 Feb 2023 Ettore Randazzo, Alexander Mordvintsev, Craig Fouts

Neural Cellular Automata (NCA) models have shown remarkable capacity for pattern formation and complex global behaviors stemming from local coordination.

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.

Growing Isotropic Neural Cellular Automata

no code implementations3 May 2022 Alexander Mordvintsev, Ettore Randazzo, Craig Fouts

Modeling the ability of multicellular organisms to build and maintain their bodies through local interactions between individual cells (morphogenesis) is a long-standing challenge of developmental biology.

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.

Image segmentation via Cellular Automata

no code implementations11 Aug 2020 Mark Sandler, Andrey Zhmoginov, Liangcheng Luo, Alexander Mordvintsev, Ettore Randazzo, Blaise Agúera y Arcas

The update rule is applied repeatedly in parallel to a large random subset of cells and after convergence is used to produce segmentation masks that are then back-propagated to learn the optimal update rules using standard gradient descent methods.

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).
