Confusion matrix
Confusion matrix evaluates a model by comparing its predictions with actual results in a tabular format. It displays a table where each cell counts rows for a specific combination of predicted and actual values, while also showing prediction errors and overall model accuracy.
To add a confusion matrix, click the Add Viewer icon on the menu ribbon and select Confusion Matrix.
To add the viewer programmatically from the console, use:
grok.shell.tv.addViewer('Confusion Matrix');
Filtering
Click a cell to filter the table to the rows of that cell. The filter applies together with the filter panel and stays when the panel changes. Click the same cell again to remove the filter, or click another cell to replace it. The filter is also removed when you close the viewer, change its columns, or reset the filters.
