QuantizationParameters

public struct QuantizationParameters : Equatable, Hashable

Parameters that determine the mapping of quantized values to real values. Quantized values can be mapped to float values using the following conversion: realValue = scale * (quantizedValue - zeroPoint).

  • The difference between real values corresponding to consecutive quantized values differing by

    1. For example, the range of quantized values for UInt8 data type is [0, 255].

    Declaration

    Swift

    public let scale: Float

  • The quantized value that corresponds to the real 0 value.

    Declaration

    Swift

    public let zeroPoint: Int
