Clustering by local gravitation
WebMar 1, 2024 · In this paper, focusing on datasets, a method called HIBOG is proposed to improve the clustering accuracy by ameliorating datasets with gravitation. HIBOG can help many clustering algorithms acquire better results on more datasets by ameliorating datasets so that similar objects get closer and dissimilar objects separate further apart.

This technique, called CLA (Z. Wang et al., 2024 ), is inspired by Newton's theory of gravitation, which reflects the relationship between a data point and its local neighbors as a local gravitation approach.

WebApr 30, 2024 · Abstract: The objective of cluster analysis is to partition a set of data points into several groups based on a suitable distance measure. We first propose a model called local gravitation among data points. In this model, each data point is viewed as an object with mass, and associated with a local resultant force (LRF) generated by its neighbors.
WebFeb 24, 2024 · It the Fig. 3, when the d c value is inappropriate, the result is very poor, because the clustering is based on the center position. If the center position is wrong, it will inevitably lead to disastrous consequences of subsequent clustering.
