RcppEnsmallen package brings to R a Header-Only C++ Mathematical
Optimization Library for Armadillo.
In particular, Ensmallen is a
templated C++ mathematical optimization library (by the MLPACK team) that provides a simple set of abstractions for writing an
objective function to optimize.
After a three month hiatus, the Ensmallen Development Team released a new patch that enabled callbacks for early stopping procedures to receive a lambda function. Outside of that, the group worked on improving automation on new update releases. The news entry for the package update sent to CRAN can be found below:
