Description The average_precision_score() function in sklearn doesn't return a correct AUC value. Steps/Code to Reproduce Example: import numpy as np """ Desc: average_precision_score returns overestimated AUC of precision-recall curve "...
Coreset is usually a small weighted subset of an input set of items, that provably approximates their loss function for a given set of queries (models, classifiers, hypothesis). That is, the maximum (worst-case) error over all queries is bounded. To obtain smaller coresets, we suggest a ...
In the case of calculating the average, we can usearray_reduceto both sum the numbers and count the elements in a single operation. Thearray_reducefunction in PHP has the following syntax: array_reduce(array$array,callable$callback,$initial=null):mixed ...
