MultilabelPPV: Positive predictive value (multilabel)
In measures: Performance Measures for Statistical Learning
View source: R/measures_multilabel.R
Description
Also called precision. Averaged ratio of correctly predicted labels for each instance,
following the definition by Charte and Charte: https: / /journal.r-project.org / archive / 2015 - 2 / charte-charte.pdf.
Fractions where the denominator becomes 0 are ignored in the average calculation.
Usage
1
MultilabelPPV(truth, response)
Arguments
truth
matrix of true values
response
matrix of predicted values
n = 20
set.seed(122)
truth = matrix(sample(c(0,1), 60, replace = TRUE), 20, 3)
response = matrix(sample(c(0,1), 60, replace = TRUE), 20, 3)
