tf.contrib.metrics.accuracy
accuracy( predictions, labels, weights=None, name=None )
Defined in tensorflow/contrib/metrics/python/metrics/classification.py
.
See the guide: Metrics (contrib) > Metric Ops
Computes the percentage of times that predictions matches labels.
Args:
-
predictions
: the predicted values, aTensor
whose dtype and shape matches 'labels'. -
labels
: the ground truth values, aTensor
of any shape and bool, integer, or string dtype. -
weights
: None orTensor
of float values to reweight the accuracy. -
name
: A name for the operation (optional).
Returns:
Accuracy Tensor
.
Raises:
-
ValueError
: if dtypes don't match or if dtype is not bool, integer, or string.
