基于非线性映射与核主成分分析的区域配电网综合评价方法
Modern Electric Power（2020）
Abstract
提出了一种基于非线性映射与核主成分分析的区域配电网综合评价方法.首先,将高维配电网评价结果经非线性映射降至二维,再利用改进的K均值聚类对二维数据进行分类;其次,用核主成分分析对存在非线性关系的配网评价指标降维,从经济性、安全性、可靠性、智能化水平4方面构建配网评价指标体系;最后,依据聚类划分和指标评价结果,分析各区域配电网的发展状况.应用所提方法对某省108个县域配电网进行综合评价,评价结果有效反映出该省108个县域配电网的发展现状并能确定其主要问题,表明了所提方法是科学有效的.

- 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
