was obtained by integrating the predicted values of each sub sequence. The results show that CEEMDAN algorithm can effectively reduce the non-stationarization of NOxsequence and it becomes easier to extract local feature information of data through SVR machine learning model with lower prediction error...
In this paper, a data set of sunspots are used to predict the activities of the sunspots by employing the support vector regression (SVR) algorithm in LS_SVM.% 支持向量机(SVM)是建立在统计学习理论基础上的一种通用的研究机器学习规律的方法。它具有很强的学习能力和泛化能力,可以有效地处理分类,...

1.项目背景麻雀搜索算法(Sparrow Search Algorithm, SSA)是一种新型的群智能优化算法,在2020年提出,主要是受麻雀的觅食行为和反捕食行为的启发。在麻雀觅食的过程中,分为发现者(探索者)和加入者(追随者),发现者在种群中负责寻找食物并为整个麻雀种群提供觅食区域和方向,而加入者则是利用发现者来获取食物。为了获得...
