Q-MINO: A Minimal-Norm Method for Quantization-Aware Training

The paper introduces Q-MINO, a Quantization-Aware Minimal-Norm Optimizer designed to improve training of ultra-low-bit neural networks. Q-MINO uses a temporal bundle method that incorporates gradient consensus, state-drift regularization, and an alignment constraint to produce stabilized, minimum-norm update directions. The authors solve the resulting constrained subproblem with a warm-started Frank–Wolfe procedure and provide theoretical convergence guarantees via a stochastic Lyapunov Kurdyka–Łojasiewicz framework, along with numerical experiments demonstrating its effectiveness across various quantization levels.

Towards Provable and Scalable Training of Quantized Neural Networks with Ising Optimization

The paper presents a Quadratic Constrained Binary Optimization (QCBO) framework that provides provable guarantees for training quantized neural networks. It characterizes the topology of zero‑loss level sets, compiles finite‑depth architectures into bounded QCBOs, and introduces a sample‑wise Decomposed Lower‑Bound Optimization (DLBO) to scale Ising‑based optimization. Experiments on a coherent Ising machine show high accuracy on binary Fashion‑MNIST at 1.1‑bit precision and validate the approach on multi‑class datasets.

Layerwise Error Attribution for Fast and Robust Mixed-Precision Post-Training Quantization

Layerwise Error Attribution for Fast and Robust Mixed-Precision Post-Training Quantization proposes a new allocation method that assigns bits to layers under a global memory budget using a small calibration set. The method derives a layerwise probabilistic analysis separating propagated error from local perturbations, enabling a simple, solver‑free allocation algorithm that is robust to corrupted calibration data. Experiments on DRUNet denoising tasks and quantized diffusion models show significant speed‑ups (up to 2,570×) and improved performance, with PSNR gains of up to 7.5 dB under corrupted calibration.
