Computes the recall@k of the predictions with respect to dense labels. (deprecated)
tf.contrib.metrics.streaming_recall_at_k( predictions, labels, k, weights=None, metrics_collections=None, updates_collections=None, name=None )
streaming_recall_at_k function creates two local variables,
count, that are used to compute the recall@k frequency. This frequency is
ultimately returned as

For estimation of the metric over a stream of data, the function creates an
update_op operation that updates these variables and returns the
recall_at_<k>. Internally, an
