WebHaving a high recall isn't necessarily bad - it just implies you don't have many false negatives (a good thing). It's similar to precision, higher typically is better. It's just a matter of what you care about more: false positives (precision) or false negatives (recall). In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space.
