Required Methods

fn log_softmax(&self, x: &mut SharedTensor<F>, result: &mut SharedTensor<F>) -> Result<(), Error>

Computes a logarithmic softmax over the input Tensor x with complete memory management.

Saves the result to result.

For a no-memory managed version see log_softmax_plain.

fn log_softmax_plain(&self, x: &SharedTensor<F>, result: &mut SharedTensor<F>) -> Result<(), Error>

Computes the logarithmic softmax over the input Tensor x without any memory management.

Saves the result to result.

Attention:
For a correct computation result, you need to manage the memory allocation and synchronization yourself.
For a memory managed version see log_softmax.

fn log_softmax_grad(&self, x: &mut SharedTensor<F>, x_diff: &mut SharedTensor<F>, result_diff: &mut SharedTensor<F>) -> Result<(), Error>

Computes the gradient of a logarithmic softmax over the input Tensor x with complete memory management.

Saves the result to result_diff.

For a no-memory managed version see log_softmax_grad_plain.

fn log_softmax_grad_plain(&self, x: &SharedTensor<F>, x_diff: &SharedTensor<F>, result_diff: &mut SharedTensor<F>) -> Result<(), Error>

Computes the gradient of a logarithmic softmax over the input Tensor x without any memory management.

Saves the result to result_diff.

Attention:
For a correct computation result, you need to manage the memory allocation and synchronization yourself.
For a memory managed version see log_softmax_grad.
