Struct FeatureMasking 

Source 
pub struct FeatureMasking { /* private fields */ }
Expand description

Feature masking strategies for GraphMAE.

Implementations§

Source§

impl FeatureMasking

Source

pub fn new(dim: usize) -> Self

Create a masking module with a learnable [MASK] token of given dimension.

Source

pub fn mask_nodes(&self, features: &[Vec<f32>], mask_ratio: f32) -> MaskResult

Randomly mask mask_ratio of nodes, replacing features with [MASK] token.

Source

pub fn mask_by_degree( &self, features: &[Vec<f32>], adjacency: &[Vec<usize>], mask_ratio: f32, ) -> MaskResult

Degree-centrality masking: higher-degree nodes are masked with higher probability.
