Abstract: An association mining method based on fractional partial calculus classification mathematical model is put forward to improve the efficiency and accuracy of association data mining under the environment of big data mining. On the basis of partial calculus principle, the fusion algorithm model based on partial calculus equations is constructed to realize the difference data fusion in the large data classification process. By means of the dual?boundary convergence control of partial differential classification mathematical model, the data set is integrated into the data model of partial calculus classification. The variation of support vector is used to realize the fuzzy control of data. The constraint bundling clustering algorithm is used to mine the data model to obtain the sub sequences. Under the conditions of minimum iteration times and convergence, the Gaussian kernel function is used to mine the association data sequence by means of measuring information control. The experimental results show that the proposed association data mining method has high mining efficiency and accuracy, and strong stability.
Keywords: partial calculus classification; mathematical model; association mining; fractional order; convergence control; mining efficiency
当前社会的信息化水平不断提升,形成了海量的大数据,大数据分类问题成为不同领域研究的热点问题。高效的大数据关联挖掘方法,为人们寻求有价值的信息提供基础,对于提升社会的信息化进程具有重要应用价值。随着计算数学研究领域的不断扩张,分析偏微积分方程的稳定解以及收敛性问题逐渐引起人们的关注[1]。因此,本文提出基于分数偏微积分分类数学模型的关联挖掘方法,提高大数据环境下关联数据挖掘的效率和精度。
1.1 基于偏微积分分类融合算法的数学模型
当前在关联数据挖掘领域中广泛采用偏微积分原理,其能够提高关联数据的高频區域,动态存储数据的低频区域,使得数据的干扰因素增加。而偏微积分原理提升数据低频区域时,存储数据的最低频区域,其对阶次的选择要求较高[2]。如果采用小阶次将降低干扰效果,采用大阶次会形成模糊问题。偏微积分原理解决离散数据过程中,无法处理待挖掘数据中噪声的干扰问题。本文在关联数据挖掘过程中采用偏微积分原理,塑造关联数据挖掘模型,实现基于偏微积分原理的差异性数据融合,提高关联数据挖掘效率。

偏微积分方程是由整数阶偏微分方程的转化产生的,偏导数是将整数阶微分方程中对函数影响因子的偏导数项进行替换得到[3]。偏微积分方程为:
