tf.contrib.metrics.streaming_mean_squared_error( predictions, labels, weights=None, metrics_collections=None, updates_collections=None, name=None )
See the guide: Metrics (contrib) > Metric
Computes the mean squared error between the labels and predictions.
streaming_mean_squared_error function creates two local variables,
count that are used to compute the mean squared error. This average is weighted by
weights, and it is ultimately returned as
mean_squared_error: 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
mean_squared_error. Internally, a
squared_error operation computes the element-wise square of the difference between
total with the reduced sum of the product of
squared_error, and it increments
count with the reduced sum of
