Struct IsseChain

Source

pub struct IsseChain { /* private fields */ }

Expand description

ISSE model: 3-level chain with cross-context hashes.

Uses contexts orthogonal to the main n-gram models:

Word-position context (captures intra-word patterns)
Byte-class transition context (captures character class patterns)
Sparse skip-2 context (captures periodic patterns)

Memory: 3 * 2MB = 6MB.

Implementations§

Source §

impl IsseChain

Source

pub fn new() -> Self

Source

pub fn predict(&mut self, c0: u32, c1: u8, c2: u8, c3: u8, bpos: u8) -> u32

Produce a prediction for the mixer.

Source

pub fn update(&mut self, bit: u8, c0: u32, bpos: u8)
