Alpenglow 1 is a free and open source C++ framework with easy-touse Python API.Alpenglow is capable of training and evaluating industry standard recommendation algorithms including variants of popularity, nearest neighbor, and factorization models.Traditional recommender algorithms may periodically rebuild their models, but they cannot adjust online to quick changes in trends.Besides batch training and evaluation, Alpenglow supports online training of recommendation models capable of adapting to concept drift in non-stationary environments.
