Forget by Uncertainty: Orthogonal Entropy Unlearning for Quantized Neural Networks

arXiv:2602.00567v2 Announce Type: replace Abstract: The deployment of quantized neural networks on edge devices, combined with privacy regulations like GDPR, creates an urgent need for machine unlearning in quantized models. However, existing methods face critical challenges: they induce forgetting by training models to memorize incorrect labels, conflating forgetting with misremembering, and employ scalar gradient reweighting that cannot resolve directional conflicts between gradients. We propose OEU, a novel Orthogonal Entropy Unlearning framework with two key innovations: 1) Entropy-guided

Why this matters
Why now

The increasing deployment of AI on edge devices and stringent privacy regulations like GDPR are pushing the need for robust machine unlearning in quantized models.

Why it’s important

This research addresses a critical technical challenge for privacy-preserving AI on constrained hardware, which is essential for broad AI adoption in sensitive applications.

What changes

The ability to more effectively 'unlearn' data from quantized neural networks improves privacy compliance and model adaptability, particularly for edge AI.
