To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]
Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
Positive recall is a term used in quality systems, most notably ISO9000.It is part of receiving inspection procedures. [1] It defines the concept that if a producer or manufacturer receives a product or process that requires inspection and it wishes to postpone the inspection process, it must have a system in place that will ensure that the postponed inspection process will take place at some ...

By computing a precision and recall at every position in the ranked sequence of documents, one can plot a precision-recall curve, plotting precision () as a function of recall . Average precision computes the average value of p ( r ) {\displaystyle p(r)} over the interval from r = 0 {\displaystyle r=0} to r = 1 {\displaystyle r=1} : [ 7 ]
The tolerance values specified by the end-user are known as specification limits – the upper specification limit (USL) and lower specification limit (LSL). [2] If the process data plotted on a control chart remains within these specification limits, then the process is considered a capable process, denoted by C ^ p k {\displaystyle {\hat {C ...
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
