How artificial neural networks build their own learning machinery

The article discusses how artificial neural networks can develop their own learning mechanisms without explicit guidance from designers. It highlights that such self-organizing networks may provide insights into the brain’s ability to reorganize itself during learning.

Building and Visualising Kolmogorov–Arnold Networks

The article "Building and Visualising Kolmogorov–Arnold Networks" explores the concept of neural networks that learn functions rather than just weights. It discusses the construction and visualization of Kolmogorov–Arnold networks, providing insights into how these networks operate and how they can be represented visually. The post was originally published on Towards Data Science.

Revenge of Monosemanticity: Neuron Specialization as a New Form of Feature Learning in MLPs

The paper investigates how multilayer perceptrons (MLPs) learn features in regression tasks with clustered data. It finds that instead of forming a single global low‑dimensional representation, MLPs develop monosemantic specialized neurons—each neuron aligns strongly with a specific predictive feature relevant to a particular region of the input space. This specialization results in a collection of local low‑dimensional representations, giving MLPs a provable data‑efficiency advantage over methods that rely on a global representation.

FlowGenesis: Representation-Driven Self-Organization of Neural Architectures

FlowGenesis is a framework that lets neural networks self‑organize their architecture during training by adding or removing neurons based on a local statistic called Representation Flux. Neurons with high Flux are split to preserve function, while low‑Flux, low‑activity neurons are pruned. Experiments on image and text classification show that networks starting from different sizes converge to similar neuron counts and performance, and the method also improves continual learning by reducing parameters for new tasks without sacrificing accuracy.

Q&A: How AI came to model the “messy” human mind

Assistant Professor Benjamin Lindquist explores how early AI engineers intentionally added randomness to models, leading to deep‑learning systems that can hallucinate. The article examines the origins of this design choice and its impact on how AI mimics the human mind’s unpredictability.
