标 题: 究竟怎样才算valid DS2019表？
发信站: BBS 未名空间站 (Wed Feb 2 22:13:21 2011, 美东)
我理解是只要DS2019 cover的那个结束日期还没到就算是valid DS2019表。（我的表
2011年7月14日是最后一天。）
可今天入境的时候被一个新手边检员刁难了一下，说我DS2019表最下面自己签字的那个
日期过了1年，这个表就无效了。。
我说DS2019表结束日期还没到，就是valid的，事实上，我刚用它返签拿到了签证的。
。。力争无效，结果，还是让我去了旁边的办公室进一步核实。
最后还是顺利入境了，但是我觉得那个边检员很奇怪，凭什么说我的DS2019表失效了？ |

发帖数: 474 | 21 any suggestion for a good approach? would like to have an elegant way to
implement this,
since this will be the requirement for all the fields across the whole
project.
tools are used:
Waffle as web framework, validation is done in controller(action),
and validation messages are exposed in ${errors},
JSP and DOJO are used.
Business requirement:
when field validation fails, change the label to red, and display the error
message with the field
thanks. |
|
g*****g
发帖数: 34805 | 22 Not familiar with Waffle, but most frameworks have a concept
of validator. e.g. Spring MVC has a validator interface that
has these two functions.
public boolean supports(Class givenClass)
public void validate(Object obj, Errors errors)
The first function specify the type of form bean,
the second one processes the form bean and append errors.
Then you can have a custom jsp tag to do view if the framework
doesn't already have one.

发帖数: 408 | 24 有没有人给个准确的理解。我认为convergence讲的是数值解能够收敛，但不一定是真
实的解。不属于validation的概念。我看有的人写paper把数值解的convergence讲成是
数值validation，我认为是不对的。
validation是把数值解跟real world的实验值对比，检查数值解的准确性。
希望各位给点意见。谢谢。 |

发帖数: 3942 | 28 correct me if i were wrong:
I think bootstrapping and cross validation have different purposes in random forest.
bootstrap: make each individual tree more independent from others, and
therefore increase the stability/decrease the variance of the whole forest;
cross validation: used to estimate generalization error and then for
evaluating different models.
In conclusion, one for model building, the other for model evaluation/validation. |

发帖数: 1239 | 29 Cross-validation 怎么理解？怎么用？
比如10-fold Cross-validation，建立regression模型
我们可以建立十个模型，并且用相对应的validation set得到的10个error rate.

一个不大的数据，十几万个record， 一百个变量，用random forest作 binary

做完之后，有十个 random forest Models
下一步 怎么做？
之后 是挑 validation error (on its set-aside 10th hold-out set) 最小的那个
Model吗？（需要一个final model 放进 production system）

建模数据少的时候 用BOOTSTRAPPING， 比如每次取70% 取500次 然后取变量系数的平

但是怎样VALIDATE 呢？ 没有其他的数据可以用啊。 没法VALIDATE的话 那岂不是可以
随便manupulate数据变量 甚至OVER-FITTING让model performance 看上起好看
