Classification (ES5)

Configure Classification Solution

javascriptCopy code
// Create classification solution (ES5 ONLY!)
// Note: Usually done via UI, shown for understanding

var solution = new GlideRecord("ml_solution")
solution.initialize()

solution.setValue("name", "Incident Category Classifier")
solution.setValue("label", "Incident Category Classifier")
solution.setValue("table", "incident")
solution.setValue("active", true)

// Capability type
solution.setValue("capability", "classification")

// Target field to predict
solution.setValue("target_field", "category")

// Input fields for training
solution.setValue("input_fields", "short_description,description")

solution.insert()

Get Classification Prediction

javascriptCopy code
// Get classification prediction for record (ES5 ONLY!)
function getClassificationPrediction(tableName, recordSysId, solutionName) {
  var predictor = new sn_ml.ClassificationPredictor(solutionName)

  var gr = new GlideRecord(tableName)
  if (!gr.get(recordSysId)) {
    return null
  }

  try {
    var result = predictor.predict(gr)

    return {
      predicted_value: result.getPredictedValue(),
      confidence: result.getConfidence(),
      top_predictions: result.getTopPredictions(5),
    }
  } catch (e) {
    gs.error("Prediction failed: " + e.message)

    if (result.getConfidence() >= 0.8) {
      current.category = result.getPredictedValue()
      current.work_notes =
        "Category auto-assigned by Predictive Intelligence " +
        "(Confidence: " +
        Math.round(result.getConfidence() * 100) +

Example Workflow

javascriptCopy code
// 1. Query ML solutions
await snow_query_table({
  table: "ml_solution",
  query: "active=true",
  fields: "name,table,capability,target_field",
})

// 2. Check model status
await snow_query_table({
  table: "ml_model",
  query: "solution.active=true",
  fields: "solution,state,accuracy,sys_created_on",
})

// 3. Test prediction
await snow_execute_script({
  script: `
        var result = getClassificationPrediction('incident', 'inc_sys_id', 'incident_classifier');
        gs.info(JSON.stringify(result));
    `,
})

Best Practices

1. Quality Data - Clean training data is essential
2. Feature Selection - Choose relevant input fields
3. Confidence Thresholds - Only apply high-confidence predictions
4. Feedback Loop - Collect user feedback
5. Regular Retraining - Update models periodically
6. Monitor Accuracy - Track prediction performance
7. Fallback - Have manual process when prediction fails
8. ES5 Only - No modern JavaScript syntax
