上一节我们跟大家介绍了一个具体的机器学习的问题,以及它的内容的设定,我们今天要继续下去做什么呢?我们今天要教大家说到底我们怎么样可以有一个机器学习的演算法来解决我们上一次提到的,判断银行要不要给顾客信用卡的问题. 那么复习一下我们上一次上了什么?我们上一次说机器学习做的事情就是,有一个演算法我们叫做 A ,这个演算法会看两件事情:一件事情是资料,我们叫做 D :另一件事情是 hypothesis set ,假说集合.我们要从这个假说集合,即 hypothesis set 里面选一个 g ,这个
Problem Description OO has got a array A of size n ,defined a function f(l,r) represent the number of i (l<=i<=r) , that there's no j(l<=j<=r,j<>i) satisfy ai mod aj=0,now OO want to know Input There are multiple test cases. Please p
并行执行 Yes! Well done! Socket clusters are initialized without variables, so a_global_var wasn't found. Fork clusters take a copy of global variables, but changes made after the cluster is created are not copied to each node. parallel包 > # A global var
