Pause a low-prevalence Label during Signal AI Studio training to unblock the system’s search for higher-prevalence labels.
When training a model in Signal AI Studio, the system automatically surfaces calls to help you find examples for your labels. However, if a label has very low prevalence — meaning the specific behavior or phrase rarely occurs in your 5,000-call sample — training can get stuck in a continual loop of no calls found. Pausing these labels lets the system focus on your higher-prevalence data and unblocks the training flow.

Why you should pause a label

Consider pausing a label if you notice:
  • Stuck training: the system can’t surface new calls for you to label.
  • Low prevalence: a label shows 0 or 1 found examples at the bottom of your training list.
  • Too many labels: you’ve created multiple small labels competing for a limited number of call examples.
Pausing a label grays it out and stops the logic from searching for those call types, letting the system retry finding truths for your active labels. When you pause a label, it will:
  • Stop surfacing calls for that label during labeling sessions.
  • Ignore current true/false counts for that label.
  • Ignore current true/false call counts toward the “Verified Calls” total.
  • Pause accuracy tracking for that label.
  • Preserve its labeled call history.
Labels can be unpaused at any time.

How to pause a label

  1. Log in to the Invoca platform and click the Signal tab, then Signal AI Studio.
  2. Select the model you’re currently training.
  3. Locate the label list in the training interface and select Verify Labels. The Transcript and Active Labels appear.
  4. Click the three-dot menu next to the label you want to stop, in the Active Labels section.
  5. Select Pause Label.
  6. The label grays out and moves into a new “Paused Labels” section below the list of labels.
  7. Repeat this for other low-prevalence labels until the system begins surfacing calls again.

How to unpause a label

  1. Navigate to your model training screen.
  2. Locate the grayed-out paused label.
  3. Click the three-dot menu next to the label name.
  4. Select Unpause Label.
  5. Click Save to refresh the training logic.
