Provides the functionality for a Backend to support Sigmoid operations.

Required Methods

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

Computes the [Sigmoid function][sigmoid] over the input Tensor x. [sigmoid]: https://en.wikipedia.org/wiki/Sigmoid_function

Saves the result to result.

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

Computes the gradient of a [Sigmoid function][sigmoid] over the input Tensor x. [sigmoid]: https://en.wikipedia.org/wiki/Sigmoid_function

Saves the result to result_diff.
