|
minLeafInstances [Optional] |
String |
叶子节点分裂阈值,取值范围>0,默认值为1。 |
|
maxTreeDepth [Optional] |
String |
树的深度-取值范围>0,默认值为5。 |
|
explanatoryDistanceRDDs [Optional] |
String |
Distance explanatory variable dataset, supporting point, line, and region datasets. |

HEAD 请求
Returns the same HTTP response headers as a GET request, but without the response body. This allows retrieving meta-information from the response headers without transporting the entire content. The meta-information includes the media type,字符编码,压缩编码,实体内容长度等。
A HEAD request can be used to check if decisionTreeRegressionFit 资源是否存在,或者客户端是否有权限访问 decisionTreeRegressionFit 资源。通过对加.<format>的 URI 执行 HEAD 请求,还可以快速判断 decisionTreeRegressionFit 资源是否支持<format>格式的表述。
