Heuristic disagreement

Is your feature request related to a problem? Please describe.
It would be good to see where heuristics disagree (and possibly how strongly).

Describe the solution you’d like
A way to filter for disagreeing heuristics. Maybe include a way to filter for the amount of disagreement. So e.g. if two active learning modules are sure (>90%) but disagree it’s a more important case than two that disagree with <20%.

Describe alternatives you’ve considered

Additional context

For Active Learning way to view the instances for which different models most strongly disagree
Disagreement between a heuristic and a model is a great simple way to get good Active Learning results. So I’d want to be able to look at (/select to view more closely and label) disagreement between any heuristics and any models.
