AIM-HER2 Scoring Heatmaps

Additive MIL based heatmaps2 highlight tissue patterns features that most contribute to AIM-HER2's score prediction. Pathologists are able to more confidently assess HER2 expression, especially in borderline cases with more slide-level heterogeneity as they can quickly and more easily focus on the most critical features and slide areas.

“I like that these heatmaps correlate to the likelihood that the region is a particular score. It gives me the immediate intuition as to the parts of the slide I should focus on.”
