Smart Assistants overview
Smart Assistants enable advanced query building and machine learning outcomes for users with little to no Search Processing Language (SPL) knowledge. Built on the backbone of the Experiment Management Framework (EMF), Smart Assistants offer a guided workflow through which you can create new Experiments. Smart Assistants let you quickly move from fitting a model on historic data to applying a model on real-time data and taking action.
There are four Smart Assistants available:
- Smart Clustering Assistant
- Smart Forecasting Assistant
- Smart Outlier Detection Assistant
- Smart Prediction Assistant
Smart Assistant workflow
Select one of the available Smart Assistants to create a new Experiment and then move through the stages of Define, Learn, Review, and Operationalize. Steps in each stage let you load data, build your model, and put that model into production.
Each stage offers data preview and visualization panels. As with Experiment Assistants, you have access to modeling history, a method to view the underlying SPL, and the option to add notes as you work.
Once you save an Experiment built with a Smart Assistant, a new knowledge object is created in the Splunk platform. This knowledge object keeps track of all the settings for the Experiment pipeline, as well as affiliated alerts and scheduled trainings.
Save your work prior to scheduling a training job for the Experiment, managing alerts for an Experiment, or deploying an Experiment.
The saved knowledge object enables you to: Organize your Experiment around solving a business problem with machine learning. Keep all of your modeling history and experimentation in one place.
Experiments are knowledge objects that are bound to the user who creates them. Experiment-built models cannot be shared in the GUI. Use the publish or export options to share models generated in an Experiment with another app or user.
Users with admin permissions can access stored MLTK model data in the following .conf file: SPLUNK_HOME/etc/users/username/Splunk_ML_Toolkit/local/experiments.conf. To learn more about .conf files, see About configurations files in the Splunk Enterprise Admin Manual.
You can operationalize your persisted models to other SPL workflows in the Splunk platform through the publish functionality, as well as create alerts for any Experiments saved within the Smart Assistant framework. When creating alerts, select from standard Trigger Conditions, or from Machine Learning Conditions that are specific to the Smart Assistant.
The following table lists the Machine Learning trigger conditions as available by Smart Assistant:
|Smart Assistant||Machine Learning Trigger Conditions|
|Smart Clustering Assistant||Triggers based on a value of cluster_distance during a scheduled search.|
|Smart Forecasting Assistant||Triggers based on a value of predicted field during a scheduled search.|
|Smart Outlier Detection Assistant||Triggers based a number of outliers during a scheduled search.|
|Smart Prediction Assistant||Triggers based on the numeric value of a predicted field during a scheduled search.|
Triggers based on the categorical value of a predicted field during a scheduled search.
Available Smart Assistants
