Why a program is not a recognizable k-means clustering, least to most advanced.

Variants

NoLoop

No While counter is less than BOUND loop.

NoAssignment

No loop over the points whose body finds each point’s nearest centroid: a loop over the centroids around a loop over the features.

NoDistance

The loop over the features does not add a term into one register.

UnsupportedTerm

The distance term reads something other than the point’s and the centroid’s feature and constants, uses an operator or calls a function a term does not have, or is ill-typed.

NotInt

A distance, but not an Int over Int arrays — the integer clustering the app computes.

NonAffineIndex

An index is not affine in the counters.

NotRowLayout

A read that is not the point’s or the centroid’s feature, row-major (row · f + feature).

NoArgmin

The loop over the centroids does not keep the nearest one (If c is 0 or dist is at most bestDist: setting best to c and bestDist to dist).

NoAccumulation

The point is not added to its nearest centroid’s row of sums and counted once.

NoUpdate

No loop over the centroids setting each to its sum over its count, or to 0 when it has no points.

NotZeroed

The sums and counts are not set to zero at the start of every epoch.

NotFromFirstPoints

The centroids do not start as the first k points.

NotCounted

A counter not set to a constant right before its loop, or not stepped by exactly one.

ExtraWork

A loop body does more than the clustering.

Trait Implementations

impl Clone for KmeansReject

fn clone(&self) -> KmeansReject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KmeansReject

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

Formats the value using the given formatter.

impl Ord for KmeansReject

fn cmp(&self, other: &KmeansReject) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KmeansReject

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for KmeansReject

fn partial_cmp(&self, other: &KmeansReject) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
