当前电力新能源工程数据呈现出多源异构、时空耦合、空间非平稳性的复杂特性,使全尺度数据挖掘区域边界模糊,导致电力新能源工程全尺度数据挖掘精度下降。为此,提出了基于空间信息多级网格的电力新能源工程全尺度数据增强挖掘方法。通过余弦相似性和皮尔逊相关系数量化数据间的关联性,在此基础上,采用相似度驱动的网格密度峰值计算方法,并结合距离阈值化处理,最终通过空间信息多级网格,实现了对复杂电力新能源数据的精细化空间划分。将划分结果标定行列索引作为特征摘要,并为网格单元特征值添加索引标记,在添加索引标记后利用反距离加权法计算挖掘索引阈值,以实现电力新能源工程的全尺度数据增强挖掘。实验结果表明,所提方法在工程全尺度数据增强挖掘中具有较高的精准度,挖掘结果与目标结果之间的一致性较强,具有较强的实用价值。
The current data of electric power new energy engineering presents complex characteristics of multi-source heterogeneity
spatiotemporal coupling
and spatial non stationarity
which make the boundaries of the full-scale data mining area fuzzy and lead to a decrease in the accuracy of full-scale data mining of electric power new energy engineering. Therefore
a multi-level grid based method for enhancing the mining of full-scale data of electric power new energy engineering based on spatial information was proposed. By quantifying the correlation between data through cosine similarity and Pearson correlation coefficient
a similarity driven grid density peak calculation method was adopted
combined with distance thresholding processing. Finally
a multi-level spatial information grid was used to achieve refined spatial partitioning of complex power new energy data. The row and column indexes of the partition results were calibrated as feature summaries
and the index labels were added to the grid cell feature values. After adding the index labels
the inverse distance weighting method was used to calculate the mining index threshold
in order to achieve full-scale data augmentation mining of power new energy engineering. The experimental data shows that the proposed method has high accuracy in engineering full-scale data augmentation mining
and the consistency between the mining results and the target results is strong. Therefore
the proposed method has strong practical value.
