Using the generator is faster than indexing, so you should prefer using it whenever possible. There are methods to start an iterator from the middle of the tree: from any offset, any index, or any key. Note that forEach has a specialized recursive implementation, which makes it the fastest...

0 - display-only; observations with a missing value for the primary split variable are not sent further down the tree. 1 - use surrogates, in order, to split observations missing the primary split variable. If all surrogates are missing, the observation is not split. 2 - use surrogates, ...
聚簇索引:也称为主键索引,是一种数据存储方式。B+Tree结构,非叶子节点包含健值和指针,叶子节点包含索引列和行数据。一张表只能有一个聚簇索引。 非聚簇索引:不是聚簇索引,就是非聚簇索引。叶子节点只是存索引列和主键id。如果sql还要返回除了索引列的其他字段信息,需要回表,第一次索引一般是顺序IO,回表的操作...
n_tree A positive integer specifying the number of trees to grow. m_try A positive integer specifying the number of variables to sample as split candidates at each tree node. The default values are sqrt(num of vars) for classification and (num of vars)/3 for regression. ...
要创建一个generator,有很多种方法。第一种方法很简单,只要把一个列表生成式的[]改成(),就创建了一个generator: 1 2 3 4 5 6 >>> L=[x*xforxinrange(10)] >>> L [0,1,4,9,16,25,36,49,64,81] >>> g=(x*xforxinrange(10)) ...
