Average Precision

It represents the weighted mean of precision achieved at each threshold, with the increase in recall from the previous threshold used as weight. It is defined as:

ap = sum[(recall(n) - recall(n-1))*precision(n)]

Example

from odin.classes import Metrics

my_metric = Metrics.AVERAGE_PRECISION_SCORE
# use my_metric as 'metric' parameter in the analyses
