This repo holds code for the NeurIPS 2024 paper Only Strict Saddles in the Energy Landscape of Predictive Coding Networks?. See this blog post for the key ideas of the paper.
All the results and plots from the paper can be reproduced from the included notebooks. All notebooks except for the convergence experiments can be run in reasonable time (< 15min) on a CPU. For the heavier convergence experiments, we recommend using a GPU.
