Struct Memory 

pub struct Memory {
    pub activation: f64,
    pub changed: u32,
    pub ignored: u32,
    pub corrected: u32,
    pub vetoed: u32,

}

One lesson’s memory.

Fields

activation: f64

changed: u32

Sessions whose result for this lesson is a change, an ignore, a correction, a veto.

ignored: u32

corrected: u32

vetoed: u32

regretted: f64

Σ credit of the regrets that blame it (outcome.rs regretted), each regret once.

tested: u32

Sessions whose own tests went green after it was asked (outcome.rs tested).

consolidated: bool

dormant: bool

Implementations

impl Memory

pub fn alpha_with(&self, w: &Weights) -> f64

α under weights w: the counts are constant-free, so one derive serves every candidate.

pub fn beta_with(&self, w: &Weights) -> f64

β under weights w.

pub fn alpha(&self) -> f64

pub fn beta(&self) -> f64

pub fn mean(&self) -> f64

pub fn weight(&self, id: &str, session: Option<&str>) -> f64

squash(A) × (0.5 + x): x the Thompson sample for (session, id), or the mean without a session.

Trait Implementations

impl Clone for Memory

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Memory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Memory

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
