Density peak clustering based on relative density relationship

Pattern Recognition, 2020
Abstract The density peak clustering algorithm treats local density peaks as cluster centers, and groups non-center data points by assuming that one data point and its nearest higher-density neighbor are in the same cluster. While this algorithm is shown to be promising in some applications, its clustering results are found to be sensitive to density

RDMN: A Relative Density Measure Based on MST Neighborhood for Clustering Multi-Scale Datasets

IEEE Transactions on Knowledge and Data Engineering, 2022
Density based clustering techniques discover the intrinsic clusters by separating the regions present in the dataset as high- and low-density regions based on their neighborhood information.

Bearing capacity-relative density behavior of circular footings resting on geocell-reinforced sand

European Journal of Environmental and Civil Engineering, 2021
Geocell reinforcement (GR) improves load-deformation behavior of shallow foundations. A series of instrumented large-scale plate load tests was performed to ascertain such improvements and to correlate that to the relative density (Dr ) of geocell ...

Effect of relative density on the compressive properties of Ti6Al4V diamond lattice structures with shells

Mechanics of Advanced Materials and Structures, 2021
It was found that stress displayed an oscillating pattern due to the discontinuous sliding process in samples under compressive loading on diamond Ti6Al4V lattice structure with shells.

Relative Density and Relative Compaction

Journal of the Soil Mechanics and Foundations Division, 1971
Since the pioneering work of R. R. Proctor some 40 years ago, soil mechanics engineers and contractors have been accustomed to evaluating a compacted fill in terms of relative compaction. Because of the many similarities, the terms relative compaction and relative density can be confused.
