CART采样代价复杂度剪枝(Cost Complexity Pruning,CCP)来进行决策树剪枝,代价复杂剪枝主要包括如下两个步骤: Step 1: 从一颗完整的决策树 T_0 开始,生成一个子树序列 \{T_0,T_1,...,T_n\} ,其中的 T_{i+1} 树由T_i 生成, T_n 为根结点; Step 2: 在子树序列中,根据真实误差选择最佳的决策树。
为了保证SNMP团体名安全性,不建议使用snmp-agent community complexity-check disable命令关闭团体名复杂度检查功能。设备对团体名复杂度的要求如下: 团体名最小长度为set password min-length命令的配置值,缺省情况下,最小长度是8个字符。 至少包含2种字符,包括:大写字母、小写字母、数字、特殊字符(不包括问号和空格)...
A simple code complexity analyser without caring about the C/C++ header files or Java imports, supports most of the popular languages. - terryyin/lizard
在决策过程中,首先需要明确的是项目的具体需求: 项目依赖的复杂度(Complexity of Project Dependencies):如果项目需要的第三方库非常多且复杂,可能需要更灵活的管理方式,这时ExternalProject更为适合。ExternalProject允许在构建过程中下载、配置、构建和安装依赖,为复杂依赖提供了更大的灵活性。 构建系统的整合性(Integration...
CCM is a tool that analyzes c, c++, c#, javascript, TypeScript and PowerShell code and reports back with cyclomatic complexity metric. Command line usage To use CCM.exe, simply use one of the two modes for invocation: CCM.exe<path-to-config-file> ...
the Simpson integral (the simple three-point formula) that there is some error, and it's easy to see that the smaller the interval, the more accurate the integral, however,if we shorten the interval, of course the results' accuracy come up, but at the cost of higher time complexity.\...
Configure block functionality for C/C++ S-functions C/C++ S-functions allow you to configure extended block functionality through various callback and SimStruct methods. Create and configure input/output ports. Specify block-based and port-based sample times. ...
缺省情况下,设备上没有配置团体名,且设备会对配置的团体名进行复杂度检查,若检查不通过,则配置不成功。为了保证SNMP团体名安全性,不建议使用snmp-agent community complexity-check disable命令关闭团体名复杂度检查功能。设备对团体名复杂度的要求如下: 团体名最小长度为set password min-length命令的配置值,缺省情况...
Years of effort have gone into optimizating SQLite, both for small size and high performance. And optimizations tend to result in complex code. So there is a lot of complexity in the current SQLite implementation. It will not be the easiest library in the world to hack. ...
Thus the overall complexity is Θ(n)*n = Θ(n^2). This is a common trick to optimize a Θ(n^3) dp algorithm for some kind of problems into a Θ(n^2) one.显然,在算法第5行循环的每次迭代中,i,j,l都是被固定的,迭代标志为l,那么,我们以k= l-1 唯一的标识算法第5行的循环的一次...
