Enum SparsityPattern 

pub enum SparsityPattern {
    Column {
        num_columns: usize,
    },
    Row {
        num_rows: usize,
    },

Sparsity pattern for structured sparsity regularization

Defines how parameters are grouped for structured sparsity. Different patterns encourage different structural zeros in the parameter matrix.

Variants

Column

Column-wise sparsity: entire columns of the parameter matrix are zeroed

Groups parameters by column index, encouraging entire columns to be sparse.

Fields

num_columns: usize

Number of columns in the parameter matrix

Row

Row-wise sparsity: entire rows of the parameter matrix are zeroed

Groups parameters by row index, encouraging entire rows to be sparse.

Fields

num_rows: usize

Number of rows in the parameter matrix

Block

Block-wise sparsity: rectangular blocks of parameters are zeroed

Groups parameters into rectangular blocks, encouraging entire blocks to be sparse.

Fields

block_height: usize

Height of each block (number of rows)

block_width: usize

Width of each block (number of columns)
