My research spans two broad areas: Natural Language Processing and Machine Learning.
Understanding human language by computers has been a central goal of AI.
Human language is an intricate system; each sentence has its own grammatical structure, inter-connected
references, and set of possible meanings. The field of Natural Language Processing (NLP) aims to build computational
models of language in order to make predictions based on real-world textual data. Example applications of NLP
include machine translation, information extraction, and question answering. Tools developed for these problems are
increasingly becoming part of daily life, from speech and dialogue systems on mobile devices to structured search on
the web to real-time translation. NLP is a rich intersection of formal modeling, applied algorithms and scalable data
systems, and has served as an important application domain for related fields such as Machine Learning (ML).
My research aligns with the Machine Learning
flagship in our faculty. In the past, I have organised the following reading groups in our faculty:
Deep Learning Reading Group,
The Machine Learning Book Reading Group, and Natural Language Processing Reading Group.
Prospective students: For PhD application, please read this before you contact me.
To international undergrad students, please email me only if you have your own funding for internship
as I do not have any funding to support interns.
- Deep learning methods, particularly why they work and how to use them well.
- Structured prediction, particularly predicting complex linguistic structure.
- Discourse, semantics, syntax, and morphology; particularly for machine translation.
- Advanced data structures (eg succinct suffix trees) for large-scale NLP problem, such as language modelling.
- Learning with limited amounts of supervision and large amount of un-annotated data; learning across different domains of data.
- Learning and inference in probabilistic graphical models, particularly for NLP problems.
- Non-parametric Bayesian models, particularly for NLP.
- Reinforcement learning, Markov decision processes, and multi-armed bandit.
- Dialogue systems, particularly with the deep learning approach.
- Learning programs from data, particularly with deep learning.
