  Electronic Health Records (EHR) can be represented as temporal sequences that
record the events (medical visits) from patients. Neural temporal point process
(NTPP) has achieved great success in modeling event sequences that occur in
continuous time space. However, due to the black-box nature of neural networks,
existing NTPP models fall short in explaining the dependencies between
different event types. In this paper, inspired by word2vec and Hawkes process,
we propose an interpretable framework inf2vec for event sequence modelling,
where the event influences are directly parameterized and can be learned
end-to-end. In the experiment, we demonstrate the superiority of our model on
event prediction as well as type-type influences learning.
