阵发性和持续性房颤的分类方法研究
Chinese Journal of Biomedical Engineering(2012)
Abstract
目前,人们对房颤维持和终止的机制还没有完全了解,因此对阵发性房颤和持续性房颤的分类具有非常重要的研究意义.鉴于此,本研究提出一种新的分类方法.根据主成分分析从单导联心电信号中提取出房颤信号,其次计算提取到的房颤信号的特征,最后用分类器对阵发性和持续性房颤进行分类.提出将房颤波的复杂度作为房颤波波动复杂度的表征.对阵发性和持续性房颤分类的实验结果表明,预测的总正确率是90%.在1 000次随机性实验中,最高分类正确率可达到92%,平均正确率为77.12%.该方法可以很好的对两类房颤进行分类,对预测房颤的自发性终止有一定的指导意义.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
