Abstract

We present a neuroscience-inspired strategy to improve the robustness of encoder models by combining Artificial Kuramoto Oscillatory Neurons (AKOrN) with PhiNet, a non-contrastive self-supervised learning approach.

AKOrN models neurons as interacting oscillators using the Kuramoto framework, while PhiNet draws inspiration from the hippocampus and temporal prediction theory to build stable, generalizable representations without relying on negative pairs.

Our motivation stems from the challenge of learning robust representations in domains such as brain imaging, where datasets are small, noisy, and highly variable. Conventional vision models tend to overfit and are vulnerable to adversarial perturbations. By integrating the oscillatory dynamics of AKOrN with the predictive structure of PhiNet, we aim to obtain models that are inherently more robust without the need for adversarial training, synthetic augmentation, or heavy post-training procedures.

Key results

Our experiments evaluate AKOrN encoders trained with several self-supervised learning methods on CIFAR-10:

Clean and robust accuracy on CIFAR-10 for an AKOrN encoder trained with SimCLR, BYOL, SimSiam and PhiNet
Adversarial robustness on CIFAR-10 with an AKOrN encoder: clean accuracy and robust accuracy under adversarial attacks, for contrastive (SimCLR) and non-contrastive (BYOL, SimSiam, PhiNet) methods.

This work was carried out during my research internship at OIST in the Machine Learning and Data Science Unit of Prof. Makoto Yamada. An extended version is available as an arXiv preprint.
