Struct believer::channel::BinarySymmetricChannel

pub struct BinarySymmetricChannel { /* fields omitted */ }

A binary symmetric channel caracterize by its error probability prob. That is, every time an input is send throught the channel, it is flipped with probability prob.

Methods

impl BinarySymmetricChannel

pub fn new(prob: f64) -> Self

Creates a new binary symmetric channel from an given prob of error.

Panic

Panic if prob is not between 0 and 1.

Trait Implementations

impl BinaryChannel for BinarySymmetricChannel

fn intrinsic_likelyhood(&self, output: GF2) -> f64

For a given output, compute log(p(output|input = 1) / p(output|input = 0)).

fn send(&self, input: GF2) -> GF2

For a given input, returns an output according to some probability distribution depending on the channel.

fn message_likelyhood(&self, output: &[GF2]) -> Vec<f64>

fn sample(&self, inputs: &[GF2]) -> Vec<GF2>

Returns a Vec of outputs as long as the inputs where each output is sample using the send method.

fn sample_uniform(&self, input: GF2, n_inputs: usize) -> Vec<GF2>

Returns a Vec of outputs where the input is send n_inputs times.
