Python implementations of the k-modes and k-prototypes clustering algorithms, for clustering categorical data - liruijia/kmodes
To calculate the new prototype for any given cluster, we will take the mode of categorical attributes of the data points in the cluster. For numerical attributes, we will use the mean of the values to calculate a new prototype for the cluster. For example, suppose that we have the followin...

Python regular expression question - sub string but not prepended with :) I'm trying to sub foo to bar, but only if it's not prepended with ie. /. So... foobar should change to barbar, but /foobar not. I've tried to add [^/] at beginning of my re, but that doesn't work ...
不过,我们这里且撇开分类(Classification)的问题,回到聚类(Clustering)上,按照前面的说法,在 k-medoids 聚类中,只需要定义好两个东西之间的距离(或者 dissimilarity )就可以了,对于两个 Profile ,它们之间的 dissimilarity 可以很自然地定义为对应的 N-gram 的序号之差的绝对值,在 Python 中用下面这样一个类来表示:...

Agglomerative clustering, and Ward’s method, in particular, provide good clustering accuracy for most applications. However, its adoption has been limited by its quadratic time complexity, which makes it slow for large datasets. It also consumes O(N2) memory for non-vectorial data. In this wor...
For example, consider the “old faithful geyser data” [in MASS R package], which can be illustrated as follow using the ggpubr R package: # Load the datalibrary("MASS") data("geyser")# Scatter plotlibrary("ggpubr") ggscatter(geyser, x ="duration", y ="waiting")+ ...
