Computes the specificity at a given sensitivity.
tf.compat.v1.metrics.specificity_at_sensitivity( labels, predictions, sensitivity, weights=None, num_thresholds=200, metrics_collections=None, updates_collections=None, name=None )
specificity_at_sensitivity function creates four local
false_negatives that are used to compute the specificity at the given
sensitivity value. The threshold for the given sensitivity value is computed
and used to evaluate the corresponding specificity.
For estimation of the metric over a stream of data, the function creates an
update_op operation that updates these variables and returns the
update_op increments the
false_negatives counts with the weight of each case
found in the
None, weights default to 1. Use weights of 0 to mask values.
