Struct PositionEncoder

pub struct PositionEncoder { /* private fields */ }

Basic position encoder that converts chess positions to vectors

Implementations

impl PositionEncoder

pub fn new(vector_size: usize) -> Self

pub fn vector_size(&self) -> usize

Get the vector size

pub fn encode(&self, board: &Board) -> Array1<f32>

Encode a chess position into a vector (optimized version)

pub fn similarity(&self, vec1: &Array1<f32>, vec2: &Array1<f32>) -> f32

Calculate similarity between two position vectors

pub fn distance(&self, vec1: &Array1<f32>, vec2: &Array1<f32>) -> f32

Calculate Euclidean distance between two vectors

pub fn encode_batch(&self, boards: &[Board]) -> Vec<Array1<f32>>

Encode multiple positions in parallel

pub fn batch_similarity( &self, query: &Array1<f32>, vectors: &[Array1<f32>], ) -> Vec<f32>

Calculate similarities between a query vector and multiple position vectors in parallel

pub fn pairwise_similarity_matrix( &self, vectors: &[Array1<f32>], ) -> Vec<Vec<f32>>

Calculate pairwise similarities between all vectors in parallel
