tf.nn.log_softmax

log_softmax(
    logits,
    dim=-1,
    name=None
)

Defined in tensorflow/python/ops/nn_ops.py.

See the guide: Neural Network > Classification

Computes log softmax activations.

For each batch i and class j we have

logsoftmax = logits - log(reduce_sum(exp(logits), dim))

Args:

• logits: A non-empty Tensor. Must be one of the following types: half, float32, float64.
• dim: 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 dim is beyond the last dimension of logits.
