摘要

最基本的无监督学习挑战是聚类。它是将元素分组成组的过程,这些组的组件与其他组中的对象“相似但不相同”。它是一种将主题分类为相似成分的簇的技术;我们尝试根据相关项的属性来识别相关项。我们发展出同质的群体或集群,它们彼此不同。另一方面,自组织地图(SOM)网络的输出并不真正提供地图上的位置组。现在安排SOM映射,以便映射上的网络大小与所需集群的数量相对应。聚类的目的是寻找一组数据集的内在分组。在本研究中,采用自组织地图和k均值聚类方法对2006年至2019年(伊拉克-库尔德斯坦地区政府电力控制与通信总局库尔德斯坦调度控制中心)的数据进行月份分类,比较了库尔德斯坦地区两种发电方法。研究发现,月份被分为三组,自组织地图算法在获得集群中距离最小的结果方面优于K-means策略。因此,SOM是数据分类的最佳和最准确的方法,这支持了它的实现。分类过程也可以通过神经网络进行调整,以解释由电模式产生的功率随时间的变化。

K-Means-Clustering and Self-Organizing Maps Comparison to Classify the Electricity Generation in Kurdistan
Most fundamental unsupervised learning challenge is clustering. It is the process of grouping elements into groups whose components are “similar but not identical” to objects in other groups. It is a technique for classifying subjects into clusters of similar components; we attempt to identify related items based on their properties. We develop homogenous groupings, or clusters, that are distinct from one another. A Self-Organizing Maps (SOM) network's output, from the other hand, does not really provide groups of locations on the map. The SOM map is now arranged so that the network size on the map corresponds to the number of clusters required. Clustering aim is to find the intrinsic grouping in a group of data set. In this study, two methods for generating power in the Kurdistan region were compared by using methods (Self Organize Maps and K-Mean Clustering) to classify the months the data was in (Iraq-Kurdistan Regional Government Ministry of Electricity General Directorate of Control &Communication Kurdistan Dispatch Control Centre) from 2006 to 2019. The research found that the months were divided into three groups, and that the Self-Organizing Maps algorithm outperformed the K-means strategy in getting the results with the lowest distance in a cluster. As a result, the SOM is the best and most accurate method for data classification, which supports its implementation. The classification process can also be adjusted by the neural network to account for changes in the power generated by electric patterns over time.
