tf.compat.v1.math.log_softmax
Computes log softmax activations. (deprecated arguments)
tf.compat.v1.math.log_softmax(
logits, axis=None, name=None, dim=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). |
dim |
Deprecated alias for axis. |
| 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. |
