Implementations

impl<I: Input, S: Storage<Item = I>> Node<I, S>

pub fn new(
    coordinate: Coordinate,
    weights: &[f64],
    time: usize,
    hit_memory_size: usize,
    storage: S
) -> Self

Creates a new instance of Node.

pub fn adjust(&mut self, target: &[f64], learning_rate: f64)

Adjusts the weights of the node.

pub fn distance(&self, weights: &[f64]) -> f64

Returns distance to the given weights.

pub fn new_hit(&mut self, time: usize)

Updates hit statistics.

pub fn is_old(&self, time: usize) -> bool

Checks whether time is considered old.
