Density Peak Clustering Algorithm Based on Relative Density [PDF]

open access: yesJisuanji gongcheng, 2023
When the density peak clustering algorithm deals with datasets with uneven density,it is easy to divide the low-density clusters into high-density clusters,divide the high-density clusters into multiple sub-clusters,and exists the error propagation ...

Density Peaks Clustering Combining Relative Local Density and Nearest Neighbor Relationship [PDF]

open access: yesJisuanji kexue yu tansuo, 2023
When the density peaks algorithm deals with datasets with different densities, the wrong center points may be selected, and the problem of associated errors may occur in the sample allocation process.

Density Peak Clustering Based on Relative Density under Progressive Allocation Strategy

open access: yesMathematical and Computational Applications, 2022
In traditional density peak clustering, when the density distribution of samples in a dataset is uneven, the density peak points are often concentrated in the region with dense sample distribution, which is easy to affect clustering accuracy.

Effects of relative densities on mechanical characteristics of interface between sand and suction caisson during penetration

open access: yesYantu gongcheng xuebao, 2022
Suction caissons are popular for mooring oil and gas platforms and fixing wind turbines. The penetration resistance is mainly the friction between the inner and outer walls during suction penetration in sand.
