# mlpack\_sparse\_coding(3)

## NAME

mlpack::sparse\_coding -

## SYNOPSIS

### Classes

class **DataDependentRandomInitializer**\
 *A data-dependent random dictionary initializer for* **SparseCoding***.*  class **NothingInitializer**\
 *A DictionaryInitializer for* **SparseCoding** *which does not initialize anything; it is useful for when the dictionary is already known and will be set with* **SparseCoding::Dictionary()***.*  class **RandomInitializer**\
 *A DictionaryInitializer for use with the* **SparseCoding** *class.*  class **SparseCoding**\
 *An implementation of Sparse Coding with Dictionary Learning that achieves sparsity via an l1-norm regularizer on the codes (LASSO) or an (l1+l2)-norm regularizer on the codes (the Elastic Net).*
