RegressionSolutionVersion - Global
The RegressionSolutionVersion API is a scriptable object used in Predictive Intelligence stores.
This API requires the Predictive Intelligence plugin (com.glide.platform_ml) and is provided
within the sn_ml namespace.
Use this API when working with solution versions based on RegressionSolution API objects in the RegressionSolution store.
The system creates a solution version each time you train a solution definition. Most versions are created during scheduled solution training.

The following example gets properties of the active object version in the store.
// Get properties
var mlSolution = sn_ml.RegressionSolutionStore.get('ml_incident_categorization');
gs.print(JSON.stringify(JSON.parse(mlSolution.getActiveVersion().getProperties()), null, 2));
Output:

"datasetProperties": {
"encodedQuery": "",

"short_description",
"sourcedc",
"targetdc",
"dbsize",
"duration"
],
"tableName": "cloudinfratext"

"datasetsProperties": [],
"name": "wc_regression"
},
"inputFieldNames": [
"short_description",
"sourcedc",
"targetdc",

RegressionSolutionVersion - getStatus(Boolean includeDetails)
Gets training completion status.
| Name | Type | Description |
|---|---|---|
| includeDetails | Boolean | Flag that indicates whether to return status details. Valid values:
Default: False |
| Type | Description |
|---|---|
| Object | JavaScript object containing training
status information
for a RegressionSolution
object. |
| <Object>.state | Training completion state. If the training job reaches a terminal state, the job does not leave that state. If the state is terminal, the hasJobEnded property
is set to true.Possible values:
Data type: String |
| <Object>.hasJobEnded | Flag that indicates whether training is complete. Valid values:
Data type: Boolean value as a String |
| <Object>.percentComplete | Training percent complete. If the completion percentage is less than 100, the job might be in a terminal state. For example, if training times out. Data type: Number as a String Range: 0 thru 100 |
| <Object>.details | Object containing a list of additional
training details. Data type: Object |
The following example shows a successful result with training complete.
// Get status
var mlSolution = sn_ml.RegressionSolutionStore.get('ml_incident_categorization');
gs.print(JSON.stringify(JSON.parse(mlSolution.getActiveVersion().getStatus(true), null, 2)));
Output:
{
"state":"solution_complete",
"percentComplete":"100",
"hasJobEnded":"true",
"details":{"stepLabel":"Solution Complete"} // This information is only returned if getStatus(true);
}
The following example shows an unsuccessful result with training complete.
// Get status
var solutionName = 'ml_x_snc_global_global_regression_solution';
var mlSolution = sn_ml.RegressionSolutionStore.get(solutionName);
var trainingStatus = mlSolution.getLatestVersion().getStatus();
gs.print(JSON.stringify(JSON.parse(trainingStatus), null, 2));

The following example shows how to display prediction results for a predict() method that takes a GlideRecord by sys_id for input and includes optional parameters to restrict to top three results and exclude the threshold value.
var mlSolution = sn_ml.RegressionSolutionStore.get('ml_incident_categorization');
// single GlideRecord input
var input = new GlideRecord("incident");
input.get("<sys_id>");
// configure optional parameters
var options = {};
options.top_n = 3;
options.apply_threshold = false;
var results = mlSolution.getVersion(1).predict(input, options);
// pretty print JSON results
gs.print(JSON.stringify(JSON.parse(results), null, 2));
