  New machine learning based algorithms have been developed and tested for
Monte Carlo integration based on generative Boosted Decision Trees and Deep
Neural Networks. Both of these algorithms exhibit substantial improvements
compared to existing algorithms for non-factorizable integrands in terms of the
achievable integration precision for a given number of target function
evaluations. Large scale Monte Carlo generation of complex collider physics
processes with improved efficiency can be achieved by implementing these
algorithms into commonly used matrix element Monte Carlo generators once their
robustness is demonstrated and performance validated for the relevant classes
of matrix elements.
