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...
The Log window shows the numerical results of clustering, namely the number of chains and clusters, the percentage of noise and the optimal values of the hyperparameters (eps,min_samples) and the metric used. Further study of the macromolecule can be carried out using the PyMol program (Optio...
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 ...
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 ...
