Identity

Versioned name: Identity-16

Category: Activation

Short description: The Identity operation forwards the input to the output.

Detailed description: The Identity operation generates a new tensor that mirrors the input tensor in shape, data type, and content, effectively implementing the linear activation function f(x) = x. If the input and output tensor data address is the same, input is returned as output instead.

Input:

• 1: input - A tensor of any shape and type T. Required.

Output:

• 1: output - A tensor with the same shape and type T as the input, containing the same data as the input.

Types

• T: any supported data type.

Example 1: 2D input matrix.
