National Institute for Applied Statistics Research Australia

The National Institute for Applied Statistics Research Australia (NIASRA) is committed to developing and applying innovative statistical methods to important problems. It undertakes a range of fundamental and contract research, major consulting projects, and professional education in statistical methodology. A number of research centres and a consulting centre are contained within NIASRA.

NIASRA’s research in applied statistics and data science is focused on Biometry and Bioinformatics, Environmental Informatics, Sample Survey Methodology, Health and Social Analytics, and Statistical Consulting. The Director of NIASRA is Professor Marijka Batterham. 

Our aim is to provide leading-edge research and consulting capacity in applied statistics for Australia and our region through the skills and activities of our staff and research students. We collaborate extensively with researchers and professionals.

This is a general presentation for anyone curious about what machine learning is (and isn’t).

Today, new technologies are generating measurements for almost everything with the ability to store these massive amounts of variables and data. There is a need to exploit such data; hence, analyses are evolving and are aiming at finding the complex relations in the data. There are many techniques to approach analysis, but some techniques are in much more “fashion” and people are wanting to use them. This is the case of “machine learning” techniques, which are sometimes referred to as if the term “machine learning” was ONE specific technique, and this is observed repeatedly in grants and proposals, where phrases like “we will use machine learning to…” are used, when in fact such a term is an umbrella term for many potential techniques. Given this, it is of importance that researchers get at least a taste of what “machine (statistical) learning” is and what it is not, and what is gained/lost in the use of some of these techniques, plus knowing that it is not a magical “one click” solution. Therefore, the aim of this talk is to give an “in a nutshell” introduction to some of the most commonly used/mentioned techniques in machine learning (ML), while also making the connection to methods in general and statistical techniques. The importance of the trade-offs of variability and bias, while presenting complex concepts in a basic manner to explain what the methods do, and that ML involves more than just “clicking a button”, will be showcased using simple one-on-one variable examples. I will hone on concepts of supervised/unsupervised learning, training and testing data sets, parameters, algorithms and cross-validation.

Presenter: Alberto Nettel-Aguirre, Professor of Biostatistics, Director of the Centre for Health and Social Analytics, NIASRA, UOW

Alberto’s first exposures to ML were in his Postdoctoral years through seminars and application of techniques while mentoring graduate students. He has developed his career working collaboratively in health and medical research and has worked extensively as a biostatistician in a range of projects. His expertise and interests cover biostatistics and methods for health and social research, machine learning, social network analysis and data science, functional data analysis and big graph data. He has incorporated the use of ML techniques (e.g. CART, Nearest Neighbours, Cluster Analysis) in various health research projects in pediatric gastrointestinal disease, neurology, and applications to biomechanics in juvenile arthritis, among others.
