View All on GitHub Revise missing history warning for item-item (and other components) about 2 months ago
AI Summary: Improve the warning mechanism in the LensKit Python recommendation toolkit's `ItemKNNScorer` (and potentially other components). The current warning for missing user history incorrectly triggers when a user is unknown in the training data. The task involves revising the warning logic to only trigger when a genuine history component is missing, possibly by checking if the query is a `RecQuery`.
