| Summary : Feature Matrix Builder
|
Description :
Generates feature matrix outputs from R object inputs using a variety
of expansion functions. The generated feature matrices have
applications as inputs for a variety of machine learning algorithms.
The expansion functions are based on coercing the input to a matrix,
treating the columns as features and converting individual columns or
combinations into blocks of columns. Currently these include expansion
of columns by efficient sparse embedding by vectors of lags, quadratic
expansion into squares and unique products, powers by vectors of
degree, vectors of orthogonal polynomials functions, and block random
affine projection transformations (RAPTs). The transformations are
magrittr- and cbind-friendly, and can be used in a building block
fashion. For instance, taking the cos() of the output of the RAPT
transformation generates a stationary kernel expansion via Bochner\'s
theorem, and this expansion can then be cbind-ed with other features.
Additionally, there are utilities for replacing features, removing rows
with NAs, creating matrix samples of a given distribution, a simple
wrapper for LASSO with CV, a Freeman-Tukey transform, generalizations
of the outer function, matrix size-preserving discrete difference by
row, plotting, etc.
