Communication Dynamics Neural Networks: FFT-Diagonalized Layers for Improved Hessian Conditioning at Reduced Parameter Count
arXiv:2605.08171v2 Announce Type: replace Abstract: Communication Dynamics Neural Networks (CDNNs) apply the circulant-spectral machinery of the Communication Dynamics framework to neural-network layer design. We introduce CDLinear, a block-circulant linear layer with block size B = 2l + 1 that uses 1/B the parameters of a dense layer with the same input and output dimensions. The construction gives an explicit Fourier-domain diagnostic for optimization: for mean-squared loss, the weight Hessian is diagonalized by the discrete Fourier transform, with eigenvalues determined directly by the Four
This paper introduces a novel neural network architecture that significantly reduces parameter count and improves optimization diagnostics, arriving as AI development pushes for more efficient models.
Improved Hessian conditioning and reduced parameter counts for neural networks can lead to more efficient training, deployment, and potentially smaller computational footprints for advanced AI models.
The explicit Fourier-domain diagnostic for optimization and the circulant-spectral layer design could fundamentally alter how certain types of neural networks are constructed and trained, especially for compute-constrained environments.

More computationally efficient and stable AI models become feasible, especially for large-scale applications.
Reduced compute requirements could broaden access to advanced AI development and deployment, particularly in regions with limited infrastructure.
This could accelerate the adoption of complex AI in novel applications, potentially leading to new industry sectors or capabilities previously bottlenecked by computational cost.
