Struct GraphAttention 

pub struct GraphAttention { /* private fields */ }

Graph Attention kernel.

Implements Graph Attention Networks (GAT) with multi-head attention. Learns to weight neighbor contributions based on their relevance to each node.

Implementations

impl GraphAttention

pub fn new() -> Self

Create a new Graph Attention kernel.

pub fn compute( graph: &CsrGraph, node_features: &[Vec<f64>], weights: &GATWeights, config: &GraphAttentionConfig, ) -> GATResult

Compute graph attention layer.

pub fn node_importance( attention_weights: &[(usize, usize, f64)], n: usize, ) -> Vec<f64>

Get node importance based on attention received.
