Provides the functionality for a Backend to support TanH operations.

Required Methods

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

Computes the [hyperbolic Tangent][tanh] over the input Tensor x. [tanh]: https://en.wikipedia.org/wiki/Hyperbolic_function

Saves the result to result.

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

Computes the gradient of [hyperbolic Tangent][tanh] over the input Tensor x. [tanh]: https://en.wikipedia.org/wiki/Hyperbolic_function

Saves the result to result_diff.
