原始数据划分为train.dat和test.dat
应用背景开始是做movielense的数据,可以把原始数据任意划分为train.dat和test.dat,主要是为了做验证实验。非常简单明了,适合初学者看看,如果不喜欢,请轻喷。关键技术# -*- coding: cp936 -*-
from sklearn import cross_validation
c = []
filename = r"Raw.data" #原始数据
out_train = open(r"train.txt","w") #训练集
out_test = open(r"test.txt","w") #测试集
for line in open(filename):
items = line.strip().split(",")
c.append(items)
c_train,c_test = cross_validation.train_test_split(c,test_size=0.1)#size =你需要的比例
for i in c_train:
out_train.write(",".join(i)+"
")
for i in c_test:
out_test.write(",".join(i)+"
")

Fortran程序设计调用10个随机数
程序会输出10个1到10之间的随机数,每次执行结果会不一样,因为是随机的。这里实例了函数返回数组的方法,主程序中要用interface来说明函数的使用接口。使用接口包括参数类型及返回值类型。

整理MiniDX字典来源数据进行排序和成千上万的代码发布…
Minidx字典整理程序源代码发布
几千条数据排序并去除重复纪录可以有很多排序算法直接内存中操作,但是假如说有几百万条记录需要处理,那就不一定适用了。这个程序最初的目的为了解决Minidx字典中重复数据的问题,但是发现写文件时I/O限制比较明显,虽然可以解决问题,但是效果却不怎么样。
工程基于VS2005,MFC的Unicode模式下编译的,利用了Sqlite3.5.0,作了C++封装处理。写处理中开启了事务.

-Finishing Minidx dictionary source code release of thousands of data to sort and remove duplicate records can have a lot of sorting algorithm to operate directly in memory, but if that has millions of records that need to be addressed, it does not necessarily apply. The original objective of this procedure in order to resolve the duplication of data dictionary Minidx, but found time to write a document I/O limitations more obvious, although the problem can be solved, but not how to effect. Works based on the VS2005, MFC compile the Unicode mode, the use of Sqlite3.5.0, made C++ Package deal. Write a deal to open the Services. Http://cn.minidx.com/index.php?option=com_content
