提高Recall要求降低模型的预警标准,比如可以把阈值s设置为0.1,此时模型的预警特征是"宁可错杀一千,绝不放过一个",但这就令模型时常报假警,带来了很低的Precision。 因此,Precision和Recall具有trade-off的关系,选择一个阈值s可能会提高Precision,但是会降低Recall,Precision与Recall本质上是对分类阈值的两种限制。那么在...

Europeis represented by around 150 ranked law schools, with a significant number of those located in the United Kingdom. Among them is theUniversity of Oxford, which states its aim is to help law students analyse complex information, construct arguments and write with precision and clarity. This...
"Precision" is what the dynamic "zero-COVID" approach emphasizes, Liang said, adding that based on local conditions, governments are required to strike a balance between the fight against the epidemic and social and economic development.■
The ATLAS Collaboration has confirmed with top quark events that the coupling of charged leptons to the weak interaction is universal — showcasing the feasibility of performing high-precision electroweak measurements at proton–proton colliders.

Using the average citation rates as expected values, errors are introduced by (1) using the mean of highly skewed distributions and (2) a specious precision in the delineations of the subsets. Classifications can be used for the decomposition, but not for the normalization. When the data is ...
Identifying reacting species locally with nanometer precision is a major challenge in electrochemical surface science. Using operando Raman nanoscopy, authors image the reversible, concurrent formation of nanometer-spatially separated Au2O3 and Au2O species during Au nanodefect oxidation. Jonas H. K. Pfist...
