trade-off between precision and recall is simple: an increase in precision can lower overall recall, while an increase in recall lowers precision. Full-text... 13 KB (1,583 words) - 08:19, 1 March 2024 |
recall implicitly causes a decrease in precision, given that factors of recall are part of the denominator. It is also inferred that a larger recall negatively... 10 KB (1,358 words) - 05:33, 23 March 2024 |
