Struct QuantParamsI4

Source

pub struct QuantParamsI4 {
    pub scale: f64,
    pub zero_point: i8,
}

Expand description

Quantization parameters for i4 (nibble-packed) tensors.

i4 values range from -8 to +7 (signed) or 0 to 15 (unsigned). Stored packed: two i4 values per byte (high nibble, low nibble).

Fields§

§scale: f64

Scale factor.

§zero_point: i8

Zero point in i4 range [-8, 7].

Implementations§

Source §

impl QuantParamsI4

Source

pub fn new(scale: f64, zero_point: i8) -> Self

Source

pub fn unpack_byte(byte: u8) -> (i8, i8)

Unpack a byte into two signed i4 values: (high_nibble, low_nibble).

Source

pub fn dequantize(&self, v: i8) -> f64

Dequantize a single i4 value to f64.
