The performance tab shows test results for several common test metrics.
The Measure list allows you to select the measures to display. The default is to display all measures. Two Sort By lists specify sort attribute and sort order. The first list is Measure, Creation Date, or Name (the default). The second list is the sort order: Ascending or Descending. (the default selection).
The Performance tab for regression model show these measures for all models:
All Measures, the default, shows all of the measures
Predictive Confidence measures how much better the predictions of the mode are than those of the naive model. Predictive confidence for regression is the same measure as Predictive Confidence for classification.
Mean Absolute Error described in Regression Statistics
Root Mean Square Error described in Regression Statistics
Mean Predicted Value, the average of the predicted values
Mean Actual Value, the average of the actual values
The top pane displays these measures as histograms.
The bottom pane contains the Models grid that supplements the information presented in the graphs. You can minimize the table using the splitter line.
The Models grid has the following columns:
Name, the name of the model along with color of the model in the graphs
Predictive Confidence
Mean Absolute Error
Root Mean Square Error
Mean Predicted Value
Mean Actual Value
Algorithm
Creation Date (and time)
By default, results for the selected model are displayed. To change the list of models, click
and deselect any models for which you do not want to see results. If you deselect a model, both the histograms and the detail information for that model are not displayed.
