Feature importance

You can pass feature importance data to a model and show the SHAP results in a graph on the model dashboard.

Uploading data

To upload feature importance data, you can either send a JSON object through the API or upload a file. The JSON object definition and the file format are described in the Feature importance topic of the API reference manual. (The image above shows the results of the example given in the API reference manual.)

UI elements

The VIANOPS model dashboard shows the feature importance data as in the image above with the following elements:

• Top X features dropdown — select to show the top 10 features, top 20 features, or all features with importance.
• Scope sliders — narrow the range of the graph to a subset of contiguous features.
• Graph of SHAP values — The features with positive impact appear in red while those with negative impact appear in blue. The length of each bar represents the normalized percentage of importance for that feature.
