描述
The training examples are accessible with the key SampKeySampKeySampKeySampKeysampKeysamp_key by
calling the operators clear_sampsetclear_sampsetClearSampsetClearSampsetClearSampsetclear_sampset and learn_sampset_boxlearn_sampset_boxLearnSampsetBoxLearnSampsetBoxLearnSampsetBoxlearn_sampset_box。You may edit the file using an editor. Every row contains an array of
attributes with corresponding class.
An example for a format might be:
(1.0, 25.3, * , 17 | 3)
This row specifies an array of attributes which belong to class 3. In this
array the third attribute is unknown. Attributes upwards 5 are supposed to be
unknown, too.
You may insert comments like /* .. */ in any place.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
参数
FileNameFileNameFileNameFileNamefileNamefile_name (输入控制) filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
Filename of the data set to train.
默认值：
'sampset1'
"sampset1"
"sampset1"
"sampset1"
"sampset1"
"sampset1"
SampKeySampKeySampKeySampKeysampKeysamp_key (输出控制) feature_set → HFeatureSet, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Identification of the data set to train.
结果
read_sampsetread_sampsetReadSampsetReadSampsetReadSampsetread_sampset 返回 2 ( H_MSG_TRUE )。
An exception is raised if it is not possible to open the file or
it contains syntax errors or there is not enough memory.
