  • Alias for sub.

    Calculates:

    output = input - other * alpha

    Gradient:

    inputGrad = outputGrad; otherGrad = -outputGrad

    Parameters

    • input: Tensor

      the input tensor of any shape

    • other: number | Tensor

      the other tensor whose shape is broadcastable with the input tensor

    • Optional alpha: number

      the alpha value to multiply other with

    Returns Tensor
