我发现H2O在R中具有功能h2o.deepfeatures以拉出隐藏层特征 https://www.rdocumentation.org/packages/h2o/versions/3.20.0.8/topics/h2o.deepfeatures
train_features <- h2o.deepfeatures(model_nn, train, layer=3)
但是我没有在Python中找到任何示例吗?谁能提供一些示例代码?
答案 0 :(得分:0)
大多数Python / R API函数都是REST调用的包装。参见http://docs.h2o.ai/h2o/latest-stable/h2o-py/docs/_modules/h2o/model/model_base.html#ModelBase.deepfeatures
因此,要将R实例转换为Python实例,请将模型移至public function getMea5() {
return $this->P10 * 2.1;
}
,所有其他arg都应重新排序。即手册中的示例变为(变量名中的点变为下划线):
this
有时函数名称会稍有变化(例如prostate_hex = ...
prostate_dl = ...
prostate_deepfeatures_layer1 = prostate_dl.deepfeatures(prostate_hex, 1)
prostate_deepfeatures_layer2 = prostate_dl.deepfeatures(prostate_hex, 2)
与h2o.importFile()
,因此您需要在http://docs.h2o.ai/h2o/latest-stable/h2o-py/docs/index.html处寻找它
