Trip end identification based on mobile phone data has been widely investigated in recent years. However, the existing studies generally use fixed clustering radii (CR) in trip end clustering algorit...
As an unsupervised learning method, the K-means clustering algorithm performs clustering operations on surrounding objects close to them by specifying a KK value as the center. Through repeated iterations, the cluster center value is updated. When the intra-class difference is smaller and the out-...
This paper proposes a registration approach rooted in point cloud clustering and segmentation, named Clustering and Segmentation Normal Distribution Transform (CSNDT), with the aim of improving the scope and efficiency of point cloud registration. Traditional Normal Distribution Transform (NDT) algorithms ...
Due to the low differentiation, it will bring some difficulties to clustering. The reason is analyzed, because the seventh and eighth data belong to PD, the characteristic gas is hydrogen, while the ninth, tenth and eleventh, twelfth data belong to D1 and D2, and acetylene is the ...
For example, Vries and Someren [53] used DTW as a trajectory similarity measure between trajectories and kernel k-means clustering. Zhao and Shi [54] used clustering results based on DTW and DBSCAN to train a recurrent neural network for real-time marine anomaly detection. Zhao and Shi [55...
In view of the high correlation of the same fault data of transformers, this paper proposes a new method for transformers’ fault diagnosis based on correlation coefficient density clustering, which uses density clustering to extrapolate the correlation coefficient of DGA data. Firstly, we calculated ...
These two parameters will directly affect the accuracy of clustering. The main concepts of DBSCAN are: Neighborhood 𝑒𝑝𝑠eps: If there is a region with radius 𝑒𝑝𝑠eps and pp is the center of this region, this region is called the neighborhood 𝑒𝑝𝑠eps of pp; Core ...
