1回答 Python sklearn与running中运行朴素Bayes的不同结果 、、、 ,我在python和R中都尝试了朴素的bayes,得到了不同的AUROC值。为什么会这样? R代码: library(bnlearn) library(pROC) library(tm) corpus <- VCorpus(VectorSource(paste(data$TEXT, sep = ' '))) dtm <- DocumentTermMatrix(corpus, control ...
etc. scipy can be compared to other standard scientific-computing libraries, such as the GSL (GNU Scientific Library for C and C++), or Matlab’s toolboxes. scipy is the core package for scientific routines in Python; it is meant to operate efficiently on numpy arrays, so that numpy and ...
