Assessing the robustness of critical behavior in stochastic cellular automata

no code implementations1 Aug 2022 Sidney Pontes-Filho, Pedro Lind, Stefano Nichele

We systematically perturb the probabilities of an optimal stochastic CA known to produce critical behavior, and we report that such a CA is able to remain in a critical regime up to a certain degree of noise.

Towards the Neuroevolution of Low-level Artificial General Intelligence

1 code implementation27 Jul 2022 Sidney Pontes-Filho, Kristoffer Olsen, Anis Yazidi, Michael A. Riegler, Pål Halvorsen, Stefano Nichele

We evaluate a method to evolve a biologically-inspired artificial neural network that learns from environment reactions named Neuroevolution of Artificial General Intelligence (NAGI), a framework for low-level AGI.

Collective control of modular soft robots via embodied Spiking Neural Cellular Automata

1 code implementation5 Apr 2022 Giorgia Nadizar, Eric Medvet, Stefano Nichele, Sidney Pontes-Filho

Voxel-based Soft Robots (VSRs) are a form of modular soft robots, composed of several deformable cubes, i. e., voxels.

A Unified Substrate for Body-Brain Co-evolution

1 code implementation22 Mar 2022 Sidney Pontes-Filho, Kathryn Walker, Elias Najarro, Stefano Nichele, Sebastian Risi

The genome of such a multicellular organism guides the development of its body from a single cell, including its control system.

Towards self-organized control: Using neural cellular automata to robustly control a cart-pole agent

1 code implementation29 Jun 2021 Alexandre Variengien, Stefano Nichele, Tom Glover, Sidney Pontes-Filho

The observations of the environment are transmitted in input cells, while the values of output cells are used as a readout of the system.

Q-Learning

A deep learning based tool for automatic brain extraction from functional magnetic resonance images in rodents

1 code implementation3 Dec 2019 Sidney Pontes-Filho, Annelene Gulden Dahl, Stefano Nichele, Gustavo Borges Moreno e Mello

In this study, we address this problem by implementing a neural network based method that uses a U-Net architecture to segment the brain area into a mask and removing the skull and other tissues from the image.

Data Augmentation

A general representation of dynamical systems for reservoir computing

1 code implementation3 Jul 2019 Sidney Pontes-Filho, Anis Yazidi, Jianhua Zhang, Hugo Hammer, Gustavo B. M. Mello, Ioanna Sandvig, Gunnar Tufte, Stefano Nichele

The advantages of such implementation are its usage on specialized and optimized deep learning libraries, the capabilities to generalize it to other types of networks and the possibility to evolve cellular automata and other dynamical systems in terms of connectivity, update and learning rules.

DeepTEGINN: Deep Learning Based Tools to Extract Graphs from Images of Neural Networks

no code implementations1 Jul 2019 Gustavo Borges Moreno e Mello, Vibeke Devold Valderhaug, Sidney Pontes-Filho, Evi Zouganeli, Ioanna Sandvig, Stefano Nichele

The goals are to simplify the training and usage of deep learning methods for computer vision and facilitate its integration into graph extraction pipelines.

Anatomy

A Conceptual Bio-Inspired Framework for the Evolution of Artificial General Intelligence

1 code implementation25 Mar 2019 Sidney Pontes-Filho, Stefano Nichele

In this work, a conceptual bio-inspired parallel and distributed learning framework for the emergence of general intelligence is proposed, where agents evolve through environmental rewards and learn throughout their lifetime without supervision, i. e., self-learning through embodiment.

Self-Learning Self-Supervised Learning

Bidirectional Learning for Robust Neural Networks

1 code implementation21 May 2018 Sidney Pontes-Filho, Marcus Liwicki

A multilayer perceptron can behave as a generative classifier by applying bidirectional learning (BL).
