类 AlgoOperator<T extends AlgoOperator<T>>

java.lang.Object

org.apache.flink.ml.operator.AlgoOperator<T>

类型参数:

T - The class type of the AlgoOperator implementation itself

所有已实现的接口:

Serializable, org.apache.flink.ml.api.misc.param.WithParams<T>, HasMLEnvironmentId<T>

直接已知子类:

BatchOperator, StreamOperator

public abstract class AlgoOperator<T extends AlgoOperator<T>>
extends Object
implements org.apache.flink.ml.api.misc.param.WithParams<T>, HasMLEnvironmentId<T>, Serializable

Base class for algorithm operators.

Base class for the algorithm operators. It hosts the parameters and output tables of an algorithm operator. Each AlgoOperator may have one or more output tables. One of the output table is the primary output table which can be obtained by calling getOutput(). The other output tables are side output tables that can be obtained by calling getSideOutputs().

The input of an AlgoOperator is defined in the subclasses of the AlgoOperator.

构造器详细资料

AlgoOperator

protected AlgoOperator()

Construct the operator with empty Params.

This constructor is especially useful when users want to set parameters for the algorithm operators. For example: SplitBatchOp is widely used in ML data pre-processing, which splits one dataset into two dataset: training set and validation set. It is very convenient for us to write code like this:

 new SplitBatchOp().setSplitRatio(0.9)
 

AlgoOperator

protected AlgoOperator(org.apache.flink.ml.api.misc.param.Params params)

Construct the operator with the initial Params.

方法详细资料

getParams

public org.apache.flink.ml.api.misc.param.Params getParams()
