Predictive Intelligence

Train classification, similarity and clustering models on your own data and use them without eroding trust.

Quick answer

Train classification, similarity and clustering models on your own data and use them without eroding trust.

Key takeaways
  • Precision and coverage matter more than raw accuracy
  • Start as a suggestion, automate once trust is earned
  • Set confidence thresholds explicitly
  • Retrain on a schedule or accuracy decays

Three model types

Classification predicts a field value, for example assignment group from short description. Similarity finds records like this one, which powers agent assist. Clustering groups records to reveal patterns, often used to find candidate problems or automation targets.

Training and evaluation

Models train on historical records with a defined filter and target field. Read the precision and coverage numbers before you deploy: a model that is 90 percent precise on 20 percent of records is useful, a model that guesses on everything is not.

Deploying carefully

Introduce predictions as suggestions before automation.

  • Show the prediction with its confidence and let the agent accept it
  • Only auto assign above a confidence threshold you agreed with the service desk
  • Retrain on a schedule, processes drift and accuracy decays
  • Exclude records created by the model itself from the next training set

Frequently asked questions

How much data do we need?
Thousands of records per class is a reasonable starting point. Sparse classes will not train well and should be excluded.
Can we explain a prediction to an auditor?
You can show the model, its training filter, its evaluation scores and the confidence of the individual prediction. That is usually what is required.
