Artificial Intelligence and Data Analytics Research Cluster

The Artificial Intelligence and Data Analytics (AIDA) Research Cluster carries out and promotes top-quality research in data science, machine learning, optimisation and artificial intelligence.

Major research areas

We cover a broad spectrum of research themes with the goal of making artificial intelligence (AI) an integral part of our daily lives.

We develop fundamental AI techniques and apply them to business and commerce, bioinformatics, e-health, sport, defence, environment, precision agriculture, energy, logistics and multimedia.

Artificial intelligence

Our research focuses on aggregation operators in AI, fuzzy systems and image processing. Fuzzy systems employ the concept of partial truth to mimic human decision-making. We build computer systems that help people make decisions from fragmented evidence and explain the logic behind those decisions.

We also focus on processing images, videos and other data to help develop autonomous systems that rely on image sensors, such as robots, rovers and drones.

Data analytics

Data analytics is about discovering patterns and properties of big and small data and developing data-driven models. Our research focuses on signal processing, smart sensing, anomaly detection, and aspects of information security and privacy.

Algorithms and optimisation

Our research covers industrial models and solutions based on discrete and continuous numerical optimisation, global optimisation, constraint satisfaction, models on graphs and data analysis methods.

We also cover development of powerful and efficient algorithms, including parallel programming and graphic processing units. We provide fundamental techniques at the core of many AI algorithms, including machine learning, clustering and regression.

Major research projects

Novel audio watermarking techniques for tracing multimedia piracy

ARC Linkage Projects; Industry partner: Flag Explore

With the rapid growth of communication networks and the use of advanced multimedia technology, digital multimedia data can be easily copied, manipulated and distributed. This has led to strong demand for new techniques to prevent illegal use of copyrighted data.

In this project, Deakin University and Flag Explore will develop inaudible, robust and high-capacity audio watermarking techniques to trace the illegal copying and distribution of multimedia data containing a sound component, such as audios and sound videos.

The outcomes of the project will greatly advance audio watermarking research, strengthen Australia’s competitiveness in this research area, and help prevent huge financial and job losses in the Australian multimedia industry.

An optimisation-based framework for non-classical Chebyshev approximation

ARC Discovery grant

This project aims to solve open problems in multivariate and piecewise polynomial approximation – two directions that correspond to fundamental obstacles to extending classical approximation results.

Through an innovative combination of optimisation and algebraic technique, this project intends to develop foundations for new results in approximation theory and new insights into other areas of mathematics (notably optimisation).

The techniques and methods developed should also have significant benefits in the many disciplines where approximation problems appear, such as engineering, physics and data mining.

Mining patterns and changes of wave shapes for efficiently querying periodic data streams


Data is becoming the world’s new natural resource, and big data use grows quickly. Useful patterns are often buried in big stream data. In this project, we re-represent raw big stream data using only critical data (or useful information) to reduce the data size and capture the principal features of the patterns to further simplify the internal data correlation.

In addition to achieving efficiency, we also simplify the data analytics problem since it's much easier to discover useful knowledge from very few simple-structured pattern-relevant data. For example, we've demonstrated that data streams can be reduced to less than 2% of their raw size without losing important information, including reduction of medical sensor stream data (to 0.85% of original size), GPS trajectory data (1.7%) and short text stream data (1.25%).

Decision-making systems for developing and improving online games

Funded by Beijing Shandesitong Technology

In this project, we aim to develop offline game decision-making systems to uncover and understand useful patterns underlying game data. These systems can be used to guide the game companies to improve their existing online games and develop new online games.

The key part of this project will be the design and implementation of generic data analysis and processing models. Built upon the models, the profitable potentials for game improvement and development will be investigated.

Scheduling and timetabling for pilot training


This project aims to develop a highly intelligent planning tool that integrates simulation, optimisation and data analysis for the daily scheduling of training lessons while, at the same time, allocate limited resources under complex resource restrictions.
