tf.contrib.metrics.accuracy

tf.contrib.metrics.accuracy(
    predictions,
    labels,
    weights=None,
    name=None
)

Defined in tensorflow/contrib/metrics/python/metrics/classification.py.

Computes the percentage of times that predictions matches labels.

Args:

• predictions: the predicted values, a Tensor whose dtype and shape matches 'labels'.
• labels: the ground truth values, a Tensor of any shape and bool, integer, or string dtype.
• weights: None or Tensor 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.
