## Interface ParallelismStrategy

- All Known Implementing Classes:
    DefaultParallelismStrategy, NoParallelismStrategy

      public interface ParallelismStrategy

  Specifies the behaviour of processes in ML-algorithms that can may be parallelized such as parallel learning in bagging, learning submodels for One-vs-All model, Cross-Validation etc.
