Из названия понятно, что будет рассказано о Mixture Density Networks, далее просто MDN,... WebSkorch allows PyTorch models to be wrapped in Scikit-learn compatible estimators. So, that means that PyTorch models wrapped in Skorch can be used with the rest of the Dask-ML API. For example, using Dask-ML’s HyperbandSearchCV or Incremental with PyTorch is possible after wrapping with Skorch. We encourage looking at the Skorch documentation ...
