dequantize(_:scale:zeroPoint:dataType:name:)

Declaration

func dequantize(_ tensor: MPSGraphTensor, scale: Double, zeroPoint: Double, dataType: MPSDataType, name: String?) -> MPSGraphTensor

Parameters

• tensor:

  Input tensor to be dequantized

• scale:

  Scale scalar parameter

• zeroPoint:

  Bias scalar parameter (converted to dataType of tensor)

• dataType:

  Float data type of the result tensor.

• name:

  The name for the operation.

Return Value

A valid MPSGraphTensor array of datatype dataType

Discussion

Convert the i8 or u8 tensor to a float tensor by applying a scale + bias transform: result = scale(tensor - zeroPoint)
