Calibration

burn_core::tensor::quantization

Enum Calibration 

Source 
pub enum Calibration {
    MinMax,
    AbsMean,
}
Expand description

Calibration method used to compute the quantization range mapping.

Variants§

§

MinMax

Computes quantization range mapping based on the min and max values.

§

AbsMean

Absolute-mean calibration for BitNet b1.58-style {-1, 0, +1} weight quantization.

The range is [-γ, +γ] where γ = mean(|W|) per tensor or per block (BitNet b1.58 §3.1). Use with QuantValue::Q2S and QuantStore::PackedU32 for 2-bit packed storage.
