[請益] bootstrap v.s. random sample

作者: brooky (未夠班)   2006-05-03 14:05:07
Hi,
This week we mentioned bootstrap as a sampling method.
It was shown that in bootstrap "test set will contain about 36.8% of
the instance and for a reasonably large dataset".
Intuitively, I can not see the difference between bootstrap and
simply using a random sample method.
In another word, why don't we just choose 63.2% from the dataset?
Is there any idea?
Thanks.
