config: HDCConfig

Configuration parameters

Implementations

impl HDCMemory

pub fn new(config: HDCConfig) -> Self

Create a new HDC memory

pub fn store(&mut self, label: String, pattern: Hypervector)

Store a pattern with its label

Arguments

• label - Label for the pattern
• pattern - Hypervector pattern to store

pub fn retrieve(&self, query: &Hypervector) -> Option<(String, f64)>

Retrieve the best matching pattern

Arguments

• query - Query hypervector

Returns

Option containing (matched_label, confidence) if a match is found

pub fn get_patterns(&self) -> &HashMap<String, Hypervector>

Get all stored patterns

pub fn remove(&mut self, label: &str) -> Option<Hypervector>

Remove a pattern

Arguments

• label - Label of pattern to remove

Returns

The removed pattern if it existed

pub fn clear(&mut self)

Clear all stored patterns

pub fn size(&self) -> usize

Get number of stored patterns

pub fn update_pattern( &mut self, label: String, new_pattern: Hypervector, learning_rate: f64, ) -> NdimageResult<()>

Update an existing pattern or store a new one

Arguments

• label - Pattern label
• new_pattern - New pattern to store
• learning_rate - Rate for updating existing patterns

pub fn store_item(&mut self, name: String, item: Hypervector)

Store item in item memory

pub fn get_item(&self, name: &str) -> Option<&Hypervector>
