Performance evaluation index of clustering algorithm on test set.

 

How-To-Use:

The input of this node is the model prediction result [target column] and the model training field [feature column].

 

Precautions:

[Target column] Only one column can be selected respectively.

❖Configuration

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

[Reserved digits of performance index] When the rounding precision is positive, the digits after the decimal point are retained; when the rounding precision is negative, the digits before the decimal point are retained.

[Real Value] Select the true value field of the pre-data node.

[Predicted value] Select the forecast value field in the forecast result.

Right-click menu of cluster evaluation:

❖Run Cluster Evaluation Node

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

 

❖Reset Cluster Evaluation Node

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

 

❖Rename Cluster Evaluation Node

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

 

❖Refresh Cluster Evaluation Node

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

 

❖Save as Composite Node

In the right-click menu of the Cluster Evaluation 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 Cluster Evaluation Node

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

 

❖Copy Cluster Evaluation Node

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

 

❖Delete Cluster Evaluation Node

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