Classification metrics based on True/False positives & negatives - Keras Computes the recall of the predictions with respect to the labels. This metric creates two local variables, true_positives and false_negatives, that are used to compute the recall.This value is ultimately returned as recall, an idempotent operation that simply divides true_positives by the sum of true_positives and false_negatives.. If sample_weight is None, weights default to 1.
