Nearest-neighbor 关于异常检测的统计分析 《Statistical analysis of nearest neighbor methods for anomaly detection》[1] Abstract Nearest-neighbor (NN)被广泛研究并用在有监督问题和无监督问题中。原paper首先在合成的benchmark数据集上把NN的方法和SOTA的算法进行比较,然后分析NN的理论性质并提出一种新的度量方式DT...
GIS is very useful in analyzing spatial relationship between features. One such analysis is finding out which features are closest to a given feature. QGIS has a tool calledDistance Matrixwhich helps with such analysis. In this tutorial, we will use 2 datasets and find out which points from ...
接下来,使用RNA和ATAC-seq数据的标准方法,独立地对两个assays 进行预处理和降维。 # RNA analysis DefaultAssay(pbmc) <-"RNA" pbmc <- SCTransform(pbmc, verbose = FALSE) %>% RunPCA() %>% RunUMAP(dims = 1:50, reduction.name ='umap.rna', reduction.key ='rnaUMAP_') # ATAC analysis # We...
NNA and the wider body of work on point pattern analysis quickly gained in sophistication, meaning that this simple test statistic only featured briefly in the frontline research literature of geographical analysis. Nonetheless, given its easy‐toゞrasp logic, it became and remains a staple of ...
