tf.contrib.losses.sigmoid_cross_entropy

Creates a cross-entropy loss using tf.nn.sigmoid_cross_entropy_with_logits. (deprecated)

weights acts as a coefficient for the loss. If a scalar is provided, then the loss is simply scaled by the given value. If weights is a tensor of size [batch_size], then the loss weights apply to each corresponding sample.

If label_smoothing is nonzero, smooth the labels towards 1/2:

new_multiclass_labels = multiclass_labels * (1 - label_smoothing)

                        + 0.5 * label_smoothing
Args
logits [batch_size, num_classes] logits outputs of the network .
multi_class_labels [batch_size, num_classes] labels in (0, 1).
weights Coefficients for the loss. The tensor must be a scalar, a tensor of shape [batch_size] or shape [batch_size, num_classes].
label_smoothing If greater than 0 then smooth the labels.
scope The scope for the operations performed in computing the loss.
Returns
A scalar Tensor representing the loss value.
Raises
ValueError If the shape of logits doesn't match that of multi_class_labels or if the shape of weights is invalid, or if weights is None.
