.. _models: Models ====== There are currently three kinds of models containing the recurrent neural networks doing all the character recognition supported by kraken: ``pronn`` files serializing old pickled ``pyrnn`` models as protobuf, clstm's native serialization, and versatile `Core ML `_ models. CoreML ------ Core ML allows arbitrary network architectures in a compact serialization with metadata. This is the default format in pytorch-based kraken.
