tf.losses.hinge_loss
Adds a hinge loss to the training procedure.
tf.losses.hinge_loss( labels, logits, weights=1.0, scope=None, loss_collection=tf.GraphKeys.LOSSES, reduction=Reduction.SUM_BY_NONZERO_WEIGHTS )
Args | |
---|---|
labels | The ground truth output tensor. Its shape should match the shape of logits. The values of the tensor are expected to be 0.0 or 1.0. Internally the {0,1} labels are converted to {-1,1} when calculating the hinge loss. |
logits | The logits, a float tensor. Note that logits are assumed to be unbounded and 0-centered. A value > 0 (resp. < 0) is considered a positive (resp. negative) binary prediction. |
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 losses dimension). |
scope | The scope for the operations performed in computing the loss. |
loss_collection | collection to which the loss will be added. |
reduction | Type of reduction to apply to loss. |
Returns | |
---|---|
Weighted loss float Tensor . If reduction is NONE , this has the same shape as labels ; otherwise, it is scalar. |
Raises | |
---|---|
ValueError | If the shapes of logits and labels don't match or if labels or logits is None. |
Eager Compatibility
The loss_collection
argument is ignored when executing eagerly. Consider holding on to the return value or collecting losses via a tf.keras.Model
