Clustering accuracy metrics
WebFeb 8, 2024 · The evaluation metric used is a metric that can measure the performance of the text clustering model using data that has a ground-truth label. In this research, three commonly used metrics are utilized to asses the quality of clusters, namely ACC [ 6 , 7 , 8 , 22 , 25 ], NMI [ 7 , 8 , 25 ], and ARI [ 8 , 26 , 27 ]. WebDec 25, 2024 · Since Clustering is unsupervised, we cannot calculate errors or accuracy or any of those metrics. In this blog, I will talk about different metrics to evaluate Clustering algorithms. Clustering is evaluated based on some similarity or dissimilarity measures such as distance between cluster points. If the algorithm can unite similar data points ...
