1. Navigate to All > Task Intelligence for ITSM > Setup to access the Task Intelligence Admin Console.
2. On the Predict incident field choices to reduce handle time card, select Set up model.
   
   This action opens the model and displays the introductory pages. Each page in the model asks you questions and helps you select the information needed to build an effective model.

Train your model

Train your incident prediction model with data to predict the incident fields.

시작하기 전에

You can set up a task intelligence model or use the base system template that is shipped with Task Intelligence for ITSM. For more information on setting up a new model, see Set up your incident prediction model.

When you train a machine learning model, the model learns patterns from past data to make predictions about new data. Models are trained using large amounts of data so that they can learn patterns. A large data set makes the learned patterns statistically significant. As you answer questions about your information systems, business process, and service operations, the system actively learns from your responses.

You can select the table and fields that you want to predict, such as the Output table and Output fields. Also, you can select the tables and fields that you want the model to use to predict the incident information, such as the Input table and Input fields.

Select this information to tell the model what to look for during training.

주:

You can either use the recommended settings or customize the settings to fit your needs.

프로시저

1. Enter a name for the model.
2. Select the Output table you want the model to predict.
3. Select Conditions to choose a set of records to use for training.
   The selected conditions determine how the model is trained. These conditions provide the requirements that a record must meet to make the predictions.
4. Select the Output fields you want the model to predict.
   
5. Select the Input table in the training data that you want the model to use to make predictions.
6. Select the Input fields that you want the model to use to make predictions.
   
7. Review the resulting Number of records in the training data based on the selected conditions.

   The records that are counted include the number of fields, parameters, and data that the model uses to train. Based on the provided information and the set conditions, the number or records gets updated automatically. The model needs a minimum of 10,000 records for effective training. If this minimum number hasn't been reached, try selecting different conditions. You can also click the refresh icon () to refresh the number.

   

8. Select Launch training.

결과

If you’re training the model on a large amount of data, training can take some time. You can request that the system sends you an email when the training is done.

Assess your model

Assess the results from the model training and view sample results for the predicted fields. Reviewing the results gives you a preview of how your model will perform after being deployed. Based on the sample results, select the prediction preference and behavior for each field.

The model has flexible options. Based on the sensitivity and requirements of each incident field on the Incident form, you can do the following actions:

• Auto-fill the predicted value in the incident field.
• Recommend the predicted value in the incident field.
• Monitor and run the prediction model for the incident field in the background only.
• Turn off the predictions for the incident field.

프로시저

1. View the number value in the Estimated number of autofilled fields section.
   The number helps you predict how your model performs when deployed.
2. Select View sample results to see the sample results for each predicted field.
3. Select the Comparison button to see the details for a selected result.
4. Choose one of the following options from the Prediction preference drop-down list for each field.

   Options	Description
   Autofill	Adds the best predicted value to the field on the Incident form.
   Recommendations	Shows the top recommended values for a field. Agents can choose to accept or reject the recommendation. You can configure the number of recommended values using Advanced Recommended actions for ITSM. For more information, see Recommended Actions for ITSM in Service Operations Workspace.
   Turn off predictions	Stops the model from performing any predictions.
   Monitor only	Monitors and runs the model in the background only without making any predictions on the incident form.

   
5. Select Save & continue.

Deploy your model

Deploy the incident prediction model to predict the incident field information.
