Computes the cosine distance between the labels and predictions.
tf.compat.v1.metrics.mean_cosine_distance( labels, predictions, dim, weights=None, metrics_collections=None, updates_collections=None, name=None )
mean_cosine_distance function creates two local variables,
count that are used to compute the average cosine distance
labels. This average is weighted by
and it is ultimately returned as
mean_distance, which is an idempotent
operation that simply divides
For estimation of the metric over a stream of data, the function creates an
update_op operation that updates these variables and returns the
None, weights default to 1. Use weights of 0 to mask values.
