Model Summary

TruEra's Model Summary provides a snapshot of the selected model, including when it was created, its data collection, training data split (when specified and available), the number of splits in the model's data collection, and the total number of features.

Here, you can see the diagnostic evaluations for a selected model across data splits for Performance, Stability, and Fairness, then quickly zero-in on the most influential features. You can also add you own MODEL NOTES to notes made by other collaborators.


Model quality tests are defined using TruEra's Python SDK. If no tests have been defined for the selected model, a notification similar to the following is displayed:

Each model summary comprises two views:

  • AI quality test results (AIQ TESTS)
  • Feature Importance (IMPORTANT FEATURES)

AIQ Tests

The quality tests defined for the selected model are listed under the AIQ TESTS tab, which summarizes the model's current test results (pictured next) and (pictured above) lists the model's currently defined tests by Test type (Performance, Stability and Fairness), the Data split, Segment, and Test metric used for the test, and the model's resulting color-coded test Score — green for passed, yellow for passed but with warnings, and red for failed. Gray indicates an undefined test result.

To view the model's diagnostic evaluation across data splits, click the arrow in the far left of title bar for the desired test to link to the diagnostic area specified by the Test type (Undefined, Performance, Fairness, Stability, or Feature Importance).

When the list is extensive, you can either search for a particular test by its name or filter the list by Test type, Data splits, Segments and/or status (Passed, passed with one or more Warnings, or Failed Tests).

You can also compare models by clicking in the Compare with list box and selecting the desired model(s) you'd like to compare.

Important Features

Visualizations of the most important features for the selected model and data split in terms of influence are found under the IMPORTANT FEATURES tab.

Important Features

The features shown have the highest average influence measured as L1 norm (absolute value). These features most often contribute, either positively or negatively, toward the final model outcome, thus making them important.

Here, you can select the Data split and the Number of features by importance you want plotted.
