Used to vote on the prediction results of multiple models on the test data set.

 

How-To-Use:

Use simple voting methods for the prediction result sets of multiple regression models, and use simple average or weighted average methods for the prediction result sets of multiple classification models;

The output of this node is the result data set after voting.After setting up voting, you can view the results after voting by connecting to the dataset view.

 

Precautions:

The front node must be Join node.

 

❖Configuration

After adding the Vote node to the experiment, you can set the Vote node through the "Configuration" page on the right.

[Voting method] simply vote: simple vote on the prediction results of multiple classification models, the minority obeys the majority, and if the predicted value of the votes is equal, one is randomly selected as the voting result; unweighted average: the prediction of multiple regression models The results are simply averaged without weight; weighted average: weighted average of the prediction results of multiple regression models.

[Only output voting results] true: only output data in one column of voting results; false: output data including irrelevant columns.

[Target column] The predicted value generated by different models requires at least two fields.

[Voting result column] Select or create a new field to store the voting result. Only one column is allowed to be selected. If the field already exists, its data will be overwritten.

 

Right-click menu of Vote:

❖Run Vote Node

Run the node, pass the data to DM-Engine for calculation, and get the output result.

 

❖Reset Vote Node

The node that has been running is reset, the returned result is deleted, and the node status is changed to not running.

 

❖Rename Vote Node

In the right-click menu of the Vote node, select "Rename" to rename the node.

 

❖Refresh Vote Node

In the right-click menu of the Vote node, select "Refresh" to update the synchronization data or parameter information.

 

❖Save as Composite Node

In the right-click menu of the Vote node, select "Save as Composite Node",The selected node can be saved as a composite node to realize a multiplexing node, and the parameters of the saved node are consistent with the original node.

 

❖Cut Vote Node

In the right-click menu of the Vote node, select "Cut" to realize node cutting operation.

 

❖Copy Vote Node

In the right-click menu of the Vote node, select "Copy" to realize node  replication operation.

 

❖Delete Vote Node

In the right-click menu of a Vote node, select "Delete" or click the delete key on the keyboard to delete the node and its input and output connections.
