Struct MinMaxObserver 

pub struct MinMaxObserver {
    pub min_val: f32,
    pub max_val: f32,
    pub bits: u32,
    pub symmetric: bool,
}

Tracks the global minimum and maximum of observed values.

Symmetric quantization: scale = max(|min|, |max|) / q_max, zp = 0. Asymmetric quantization: scale = (max − min) / (2^bits − 1).

Fields

min_val: f32

Running minimum value.

max_val: f32

Running maximum value.

bits: u32

Quantization bit-width.

symmetric: bool

Symmetric (zero-point = 0) vs asymmetric.

Implementations

impl MinMaxObserver

pub fn new(bits: u32, symmetric: bool) -> Self

Create a new MinMaxObserver.

Panics

Panics if bits is 0 or > 16.
