Provides the functionality for a Backend to support Sigmoid operations.

Required Methods

Computes the Sigmoid function over the input Tensor x with complete memory management.

Saves the result to result.

For a no-memory managed version see sigmoid_plain.

Computes the Sigmoid function 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 sigmoid.

Computes the gradient of a Sigmoid function over the input Tensor x with complete memory management.

Saves the result to result_diff.

For a no-memory managed version see sigmoid_grad_plain.

Computes the gradient of a Sigmoid function 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 sigmoid_grad.
