The loss (objective) function must be defined in a C++ +module. The optimization problem is solved using a coordinate gradient +descent algorithm.

Use of parallel +computing for cross validation and subsampling is supported through the +@code{foreach} and @code{doParallel} packages.") + (license license:gpl2+))) |
