Neuroevolution Paper
gene expression, connectomes, and metalearning
A few years into my mid-career pivot into science, I just landed my first published paper! What started as an idea I wrote on a napkin at the Cosyne neuroscience conference is finally out in Nature Communications: “Complex computation from developmental priors”. […] In the paper, my neuroscience collaborator Dániel and I describe how to cast neuroevolution as a metalearning problem, by treating his XOX model of connectome generation as a differentiable step in the two-stage …

Spatial Game Theory
package for experiments in evolutionary spatial game theory
SGT is a Mathematica package to unlock effortless explorations in evolutionary spatial game theory. Using SGT, you can setup, conduct and visualize experiments using a small number of functions and symbolic expressions to specify the initial distribution of agents, the topology of the grid, the strategies the agents employ, the payoff structure of the games they play, the rules used to update the agents and apply natural selection, whether and how mutation occurs, whether agents have access to …

Floatworld
evolutionary sim of RNN-controlled agents on a gridworld
floatworld is an C++ library and associated GUI that serves as a laboratory for a multi-agent RNN-based simulation in which agents compete for space and energy on a two-dimensional grid. I wrote floatworld, along with a short paper about it, during my undergraduate degree. Each agent is controlled by a recurrent neural network and harvests energy in order to reproduce. Time and space are discretized. Agents obtain a variety of data from their environments that is fed to their neural network …
