Toward Multi-Domain and Long-Tailed Quantization via Feature Alignment and Scaling

arXiv:2606.04920v1 Announce Type: new Abstract: Quantizing deep neural networks is essential for efficient inference on resource-constrained devices. However, most existing methods are designed for single-domain and class-balanced data, leaving practical settings with domain shifts or severe class imbalance underexplored. We address these challenges with Efficient Multi-Domain Alignment Quantization (EmaQ), which aligns domain distributions through a CDF-based projection and uses sensitivity-aware weight aggregation to stabilize multi-domain quantization. We further extend EmaQ to EmaQ-LT for

Why this matters
Why now

The increasing demand for efficient AI deployment on diverse, resource-constrained devices, often facing real-world data complexities like domain shifts and class imbalance, drives the need for advanced quantization techniques.

Why it’s important

This research addresses critical limitations in deploying AI, particularly for edge computing and embedded systems, making AI more accessible and practical across varied operational environments.

What changes

The ability to quantize deep neural networks effectively for multi-domain and long-tailed data will enable a broader and more robust application of AI on hardware that previously struggled with such complexities.
