AbsBackprop

Versioned name: AbsBackprop-1

Category: Arithmetic

Short description: AbsBackprop computes gradient for Abs

\[\begin{split}ds = \begin{cases} dd & \text{if } s>0 \\ -dd & \text{if } s<0 \\ 0 & \text{if } s=0 \end{cases}\end{split}\]

Inputs:

• 1: input_forward - original input tensor of Abs op. Required.

  • Type: T

• 2: output_delta - the gradient tensor with respect to the output. Required.

  • Type: T

Outputs

• 1: input_delta - the gradient tensor with respect to the input of Abs.

  • Type: T

Types:

• T: f32, f16, bf16.

• Note: Inputs and outputs have the same data type denoted by T. For example, if input is f32 tensor, then all other tensors have f32 data type.
