jax.nn.log_softmax

jax.nn.log_softmax(x, axis=-1)

Log-Softmax function.

Computes the logarithm of the softmax function, which rescales elements to the range \([-\infty, 0)\).

\[\mathrm{log\_softmax}(x) = \log \left( \frac{\exp(x_i)}{\sum_j \exp(x_j)} \right)\]

Parameters

axis – the axis or axes along which the log_softmax should be computed. Either an integer or a tuple of integers.
