tf.metrics.true_negatives(
labels, predictions, weights=None, metrics_collections=None,
updates_collections=None, name=None
)
If weights
is None
, weights default to 1. Use weights of 0 to mask values.
Args | |
---|---|
labels
|
The ground truth values, a Tensor whose dimensions must match
predictions . Will be cast to bool .
|
predictions
|
The predicted values, a Tensor of arbitrary dimensions. Will
be cast to bool .
|
weights
|
Optional Tensor whose rank is either 0, or the same rank as
labels , and must be broadcastable to labels (i.e., all dimensions must
be either 1 , or the same as the corresponding labels dimension).
|
metrics_collections
|
An optional list of collections that the metric value variable should be added to. |
updates_collections
|
An optional list of collections that the metric update ops should be added to. |
name
|
An optional variable_scope name. |
Returns | |
---|---|
value_tensor
|
A Tensor representing the current value of the metric.
|
update_op
|
An operation that accumulates the error from a batch of data. |
Raises | |
---|---|
ValueError
|
If predictions and labels have mismatched shapes, or if
weights is not None and its shape doesn't match predictions , or if
either metrics_collections or updates_collections are not a list or
tuple.
|
RuntimeError
|
If eager execution is enabled. |
