Graphlab - 如何在随机森林分类器中设置树参数的数量
Graphlab - How to set the number of trees parameter in random forest classifier
我正在训练随机森林分类器:
model = gl.random_forest_classifier.create(train, target = 'label',row_subsample = 0.5, column_subsample = 0.75, validation_set=validation, metric="auc", max_iterations=10, max_depth = 15)
如何设置树数参数?这是一个二进制分类问题,文档说:
max_iterations : The maximum number of iterations to perform. For multi-class classification with K classes, each iteration will create K-1 trees.
"The num_trees
keyword argument is deprecated. Please use the max_iterations
argument instead. Any value provided for num_trees
will be used in place of max_iterations
."
所以,调整max_iterations
也就是调整树的数量参数。
