摘要

提出了一种改进的快速独立矢量分析（FastIVA）算法。该算法将二阶导数替换为原函数及其一阶导数，并引入自适应比例因子，有效减少了迭代次数和计算时间。实验基于PNL非语音语料库和ATR日语语音数据库构建的混合数据集进行。实验结果表明，改进算法的分离性能与传统的FastIVA相当，同时显著减少了迭代次数和运行时间。

An Improved Fast Independent Vector Analysis Algorithm for Enhanced Efficiency

This paper proposes an improved fast independent vector analysis (FastIVA) algorithm. The proposed algorithm replaces the second-order derivative with the original function and its first derivative, incorporating an adaptive scaling factor to effectively reduce the number of iterations and computation time. The experiments are conducted based on a hybrid dataset constructed from the PNL Non-Speech Corpus and the ATR Japanese Speech Database. Experimental results demonstrate that the improved algorithm achieves separation performance comparable to the traditional FastIVA while significantly reducing both the iteration count and runtime.
