A New Density Peak Clustering Algorithm Based on Cluster Fusion
When the density peak clustering algorithm deals with complex datasets and the problem of multiple density peaks in the same cluster, the subjectively selected cluster centers are not accurate enough, and the allocation of noncluster centers is prone to joint and several errors To solve the above problems, we propose a new density peak clustering Optical Breast Spectroscopy (OBS) has been shown to predict mammographic breast density, a strong breast cancer risk factor OBS is a lowcost technique applicable at any age OBS information may be useful for personalizing breast cancer screening programs based on risk to improve consensus on and a A multiwavelength, laserbased optical spectroscopy device
Breast cancer screening in women with extremely dense breasts
Abstract Breast density is an independent risk factor for the development of breast cancer and also decreases the sensitivity of mammography for screening Consequently, women with extremely dense breasts face an increased risk of late diagnosis of breast cancer These women are, therefore, underserved with current mammographic Density Peak (DPeak) clustering algorithm is not applicable for large scale data, due to two quantities, ie, ρ and δ, are both obtained by brute force algorithm with complexity O (n 2)Thus, a simple but fast DPeak, namely FastDPeak, 1 is proposed, which runs in about O (n l o g (n)) expected time in the intrinsic dimensionality It replaces Fast density peak clustering for large scale data based on kNN
