Struct GraphStructuredSparsitySelector 

pub struct GraphStructuredSparsitySelector<State = Untrained> { /* private fields */ }

Graph-based structured sparsity selector

Implements structured sparsity regularization for graph-structured feature relationships. This encourages smoothness over connected features in the graph.
