Spatial constraint types for spatial mixture models

Different types of spatial constraints can be applied to mixture models to incorporate spatial relationships and ensure spatial coherence in clustering.

Variants

Adjacency

Adjacency-based spatial constraint using neighbor relationships

Uses topological adjacency to define spatial relationships. Neighboring spatial units influence each other’s cluster assignments.

Distance

Distance-based constraint with specified radius

Spatial units within a given distance radius influence each other. The radius parameter controls the spatial influence range.

Fields

radius: f64

Grid

Grid-based constraint for regular spatial patterns

Assumes data is arranged in a regular grid pattern. Neighboring grid cells influence each other based on grid topology.

Fields

rows: usize

cols: usize

Custom

Custom spatial constraint with user-defined relationships

Allows for arbitrary spatial relationship definitions. Users can provide custom spatial weights matrices.

Implementations

impl SpatialConstraint

pub fn requires_coordinates(&self) -> bool

Check if the constraint requires coordinate information

pub fn requires_grid_dimensions(&self) -> bool

Check if the constraint requires grid dimensions

pub fn constraint_name(&self) -> &'static str

Get a descriptive name for the constraint type

Trait Implementations

impl Clone for SpatialConstraint

fn clone(&self) -> SpatialConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpatialConstraint

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

Formats the value using the given formatter.

impl Default for SpatialConstraint

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SpatialConstraint

fn eq(&self, other: &SpatialConstraint) -> 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.
