tf.metrics.false_positives_at_thresholds
Computes false positives at provided threshold values.
tf.metrics.false_positives_at_thresholds( labels, predictions, thresholds, 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 | A Tensor whose shape matches predictions . Will be cast to bool . |
predictions | A floating point Tensor of arbitrary shape and whose values are in the range [0, 1] . |
thresholds | A python list or tuple of float thresholds in [0, 1] . |
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 false_positives should be added to. |
updates_collections | An optional list of collections that update_op should be added to. |
name | An optional variable_scope name. |
Returns | |
---|---|
false_positives | A float Tensor of shape [len(thresholds)] . |
update_op | An operation that updates the false_positives variable and returns its current value. |
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. |
