WebJan 19, 2024 · Just take the average of the precision and recall of the system on different sets. For example, the macro-average precision and recall of the system for the given example is Macro-average precision = P 1 + P 2 2 = 57.14 + 68.49 2 = 62.82 Macro-average recall = R 1 + R 2 2 = 80 + 84.75 2 = 82.25

Here is for the mean: WebSep 25, 2015 · For a 2x2 confusion matrix, the accuracy is typically defined as: While the g-mean is defined as (see, e.g., Espindola & Ebecken 2005) Where Precision = T P T P + F P, Recall = Sensitivity = T P T P + F N, and Specificity = T N T N + F P. These two definitions give different results so it is important to be clear which is being used.
WebAccuracy. The accuracy of instrumentation is determined by the difference of a measured value compared to its actual (true) value. As no measurement is 100% exact an element of inaccuracy needs to be considered, hence the reason why accuracy figures are quoted with ‘±’. Ultimately, accuracy measures how close you come to the correct result.
