New calibration method boosts low-bit quantization for speech models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method called Evolution Strategy-based Calibration (ESC) to improve the quantization of speech models. This technique addresses the specific challenges of audio signals, which often exhibit large calibration ranges that can lead to information loss with standard methods. ESC formulates activation scaling as an optimization problem, enabling speech models to maintain performance under INT8 quantization and achieve near-lossless results with INT4 quantization. AI

IMPACT Enables more efficient deployment of speech models by improving quantization techniques.
