NeuronSoup: Evolving Asynchronous, Shared-Neuron Temporal Graphs without Backpropagation

arXiv:2607. 15217v1 Announce Type: cross Abstract: We present NeuronSoup, a neural computation architecture that replaces synchronous layer-by-layer processing with asynchronous, delay-mediated signal propagation through a pool of shared neurons.

Genetic algorithm vs. gradient descent for training a neural network architecture dedicated to low data regimes in small medical datasets

The paper compares genetic algorithm (GA) and gradient descent (GD) training for a distance‑encoding biomorphic‑informational neural network (DEBI‑NN) designed for low‑data medical datasets. A spatial backpropagation scheme was implemented for GD, and both optimizers were evaluated on synthetic, radiomic, and fetal cardiotocography datasets. Across all experiments, GA consistently outperformed GD, achieving higher classification accuracy and more stable decision boundaries, while GD struggled with the interdependent spatial parameters of DEBI‑NN.

Multi-Behavioral Evolved Substrates Through Neuromodulation and Activation Selection

The paper investigates whether artificial evolution can replicate biological neuromodulation and diverse neuron types in indirectly encoded substrates. Experiments show that neuromodulation alone cannot overcome a 75% performance ceiling on parity tasks, but combining neuromodulation with per‑task activation function selection allows a single evolving genotype to achieve 100% success across five tasks. This demonstrates that both neuromodulation and evolvable computational primitives are necessary for multi‑behavioral open‑ended evolution.
