tf.nn.log_softmax
Computes log softmax activations.
tf.nn.log_softmax(
logits, axis=None, name=None
)
For each batch i
and class j
we have
logsoftmax = logits - log(reduce_sum(exp(logits), axis))
Args |
logits | A non-empty Tensor . Must be one of the following types: half , float32 , float64 . |
axis | The dimension softmax would be performed on. The default is -1 which indicates the last dimension. |
name | A name for the operation (optional). |
Returns |
A Tensor . Has the same type as logits . Same shape as logits . |
Raises |
InvalidArgumentError | if logits is empty or axis is beyond the last dimension of logits . |
