Method, System, and Computer Program Product for Recurrent Neural Networks for Asynchronous Sequences

Abstract:

A method for recurrent neural networks for asynchronous sequences may include receiving first input data associated with a plurality of first data items ordered in a first sequence and second input data associated with a plurality of second data items ordered in a second sequence. Each first data item may be of a first type, and each second data item may be of a second type. Each respective data item of the first and second data items may be inputted with an indicator associated with a respective type of the respective data item to a recurrent unit of a recurrent neural network (RNN). A respective portion of a hidden state may be determined based on the indicator. The respective portion of the hidden state may be updated based on the respective data item and the indicator. A system and computer program product are also disclosed.
