WebApr 10, 2024 · Droplet-based nuclei-capture and library preparation were performed on replicate samples from eight male donors without history of psychiatric or neurological disorder. Unsupervised clustering identified major neural cell classes. Subsequent iterative clustering of neurons further revealed 20 excitatory and 22 inhibitory subclasses. WebDetails. The data given by x are clustered by the k k -means method, which aims to partition the points into k k groups such that the sum of squares from points to the assigned cluster centres is minimized. At the minimum, all cluster centres are at the mean of their Voronoi sets (the set of data points which are nearest to the cluster centre). small microwave ovens 700w https://holybasileatery.com
