Struct LevelEncoder 

pub struct LevelEncoder {
    pub levels: Vec<BipolarHv>,
    pub x_min: f64,
    pub x_max: f64,
}

Level encoder: maps a continuous scalar to one of n_levels discrete bipolar hypervectors.

Consecutive level hypervectors differ by exactly dim / n_levels bits, giving them a graded similarity profile (thermometer-like in HV space).

Fields

levels: Vec<BipolarHv>

Ordered level hypervectors (index 0 = lowest value).

x_min: f64

Lower bound of the encoded range.

x_max: f64

Upper bound of the encoded range.

Implementations

impl LevelEncoder

pub fn new(n_levels: usize, dim: usize, x_min: f64, x_max: f64) -> Self

Build a new LevelEncoder with n_levels equally spaced levels.

Construction: levels[0] is a random HV; each subsequent level flips dim / n_levels randomly chosen positions (without replacement within each step).

pub fn encode(&self, x: f64) -> &BipolarHv

Quantise x to the nearest level and return a reference to its HV.
