Creating, sharing, and deleting models in the Machine Learning Toolkit

The Splunk Machine Learning Toolkit (MLTK) provides custom search commands for machine learning. These commands use model files to store machine learning algorithm results on a dataset. This model can then be applied to other datasets.

About Models

Models are Splunk platform knowledge objects with configurable sharing and permissions. Models store in the same way as lookups.

Under the Models tab of the MLTK navigation bar, access any models created using the fit command on the Search tab, or those made using the Classic layout of the guided modeling Assistants. By default, user-level (private) models store here: $SPLUNK_HOME/etc/users/admin/Splunk_ML_Toolkit/lookups

Model size is impacted by the data used and the chosen algorithm. Maximum model size is configurable and can be viewed within the MLTK Settings (Settings/ Algo Name/ max_model_size_mb).

Creating and using models

By default, MLTK models created with the fit command are created in the namespace of the user who ran the search. Models are created using the fit command and applied to datasets using the apply command. For more details, see:

Sharing models from other Splunk apps

The MLTK can access pre-trained models provided by other Splunk apps, provided the following settings are in place:

  1. The pre-trained model has its sharing level set to global using standard knowledge object access settings.
  2. The pre-trained model does not have the same name as a model that already exists in the MLTK.

Deleting models

You can also delete models through the Models page. Follow these steps to delete a model:

  1. Click Models on the MLTK navigation bar.
  2. On the Models page, select the model that needs deletion.
  3. Click Delete in the Actions column.
  4. In the Delete Model window, click Delete again to verify that you want to delete the model.
