Calculates the mean of the per-class accuracies.
tf.compat.v1.metrics.mean_per_class_accuracy(
labels,
predictions,
num_classes,
weights=None,
metrics_collections=None,
updates_collections=None,
name=None
)
Calculates the accuracy for each class, then takes the mean of that.
For estimation of the metric over a stream of data, the function creates an
update_op
operation that updates the accuracy of each class and returns
them.
If weights
is None
, weights default to 1. Use weights of 0 to mask values.
