1) estimation of total number of clusters 类数目估计 1. In this paper, five issues commonly concerned are discussed, they are: assessment of clustering results,estimation of total number of clusters, data preparation, measures of data proximity and outlier handling. ...
Numerous reports have elucidated the classification of a large amount of data using various clustering techniques. However, an increase in data size hinders the applicability of these methods. Here, it is investigated how to deal with the exploding number of possibilities to be sorted into ...
Second, an equation is given for the total number of candidate mixture models in multivariate normal mixture model based clustering. The number of candidate mixture models is defined as the sum of the number of possible mixture models with different number of component clusters.Tayfun Servi...
The investigation indicates a critical Peclet number, Peg, beyond which gravitational influence reinforces particle adhesion, leading to particle clustering; the magnitude of the effect is inversely related to the Peg value. Our results, remarkably, concur with an experimentally established Pe threshold ...
Quality control, clustering, cell type annotation and normalized UMI For each sample, we first filtered out cells based on number of genes expressed, total UMI counts and proportion of total UMI counts derived from mitochondrial genes. We also removed cells that were detected as doublets. After ...
The fitting curve of TDS content versus ice thickness shows a decrease in TDS with increasing ice thickness, even though the number of date points is limited, following a negative exponential-like trend. The curve decreases rapidly at the beginning of ice formation, and then reaches an almost ...
Our goal is to develop mathematical tools needed to study the consistency, as the number of available data points increases, of graph-based machine learning algorithms for tasks such as clustering. In particular, we study when the cut capacity, and more generally total variation, on these graphs...
In particular, a specific branch & bound algorithm [Potts and Wassenhove, 1985] has been found to be unable to solve a substantial number of instances with 50 jobs within 120 CPU seconds on an HP 9000-G50 computer; furthermore, it has been reported that the computation times for solving ...
The total number of natural fractures, their lengths, and inter-fracture spacing were generated assuming they will follow normal distributions (Weng et al., 2011). The statistical parameters used to generate natural fractures with different relative angles are given in Table 2 and the corresponding ...
