eHarmony/aloha

The Aloha libraries provide implementations of machine learning models used at eHarmony. So, Aloha models are are not written in terms of Instances, Tensors, or DataModels. Instead, models are written generically, and different semantics implementations are provided to give meaning to the features extracted from the arbitrary input types on which the models operate. While these differences may not sound extremely useful, together they produce a number of advantages. The most notable is probably the way input features make their way to the models.
