*Title:        *Knowledge Efficient Deep Learning for Natural Language
Processing

*Abstract: *
Deep learning has become the workhorse for a wide range of natural language
processing applications. But much of the success of deep learning relies on
annotated examples.  Annotation is time-consuming and expensive to produce
at scale. Here we are interested in methods for reducing the required
quantity of annotated data --- by making the learning methods more
knowledge efficient so as to make them more applicable in low annotation
(low resource) settings. There are various classical approaches to making
the models more knowledge efficient such as multi-task learning, transfer
learning, weakly supervised and unsupervised learning etc. This thesis
focuses on adapting such classical methods to modern deep learning models
and algorithms.

I describe four works aimed at making machine learning models more
knowledge efficient. First, we propose a knowledge rich deep learning model
(KRDL) as a unifying learning framework for incorporating prior knowledge
into deep models. In particular, we apply KRDL built on Markov logic
networks to denoise weak supervision. Second, we apply a KRDL model to
assist the machine reading models to find the correct evidence sentences
that can support their decision. Third, we investigate the knowledge
transfer techniques in multilingual settings, where we proposed a method
that can improve pre-trained multilingual BERT based on the bilingual
dictionary. Fourth we present an episodic memory network for language
modelling, in which we encode the large external knowledge for the
pre-trained GPT.
