Sum the weights of false positives.
tf.metrics.false_positives( 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. |
