Executive Impact: Unlocking Robust & Reliable AI
This paper introduces Geometry-Aware Learning (GAL), a novel layer-wise training framework for deep neural networks. GAL sculpts internal representations, promoting intra-class compactness and inter-class separation, leading to manifold smoothness and enhanced adversarial robustness. Unlike traditional end-to-end backpropagation, GAL's local learning mechanism, explained by a Hopfield-like energy model, effectively disentangles semantically meaningful information and reduces representation interference. This approach offers a promising direction for understanding robust learning in both artificial and biological neural networks, mitigating adversarial attacks while maintaining high classification accuracy.

Geometric Foundations of GAL
Explore how the Geometry-Aware Learning (GAL) framework leverages geometric principles to sculpt internal representations, promoting intra-class compactness and inter-class separation in feature space. This leads to manifold smoothness and robust decision boundaries, which are crucial for mitigating adversarial attacks.
Enhanced Adversarial Robustness
Delve into GAL's enhanced adversarial robustness against both white-box (FGSM) and black-box attacks. Unlike standard backpropagation, GAL's layer-wise approach significantly reduces vulnerability by creating more robust and disentangled representations, making networks less susceptible to subtle perturbations.
Biological Plausibility of Learning
Understand the biological inspiration behind GAL, particularly its connection to Hopfield-like energy models and Hebbian learning. The framework's ability to drive progressive nucleation and form archetypal representations in a layer-dependent manner mirrors learning processes observed in biological neural networks.

GAL in Image Classification: MNIST & CIFAR-10
Our experiments on MNIST and CIFAR-10 datasets demonstrate GAL's superior performance. Despite using a layer-wise training strategy, GAL achieves comparable classification accuracy to backpropagation, while significantly boosting adversarial robustness. For instance, under FGSM attacks, GAL-trained networks maintained high accuracy where traditional models failed. This proves GAL's ability to learn semantically meaningful, robust features.
Outcome: Enhanced robustness, stable accuracy.
