Ihaka Lecture Series

In March 2017 the Department of Statistics launched a new, annual lecture series named after Associate Professor Ross Ihaka in honour of his contributions to the field. Find out about the 2019 lecture series below.

Associate Professor Ross Ihaka

Ross Ihaka, along with Robert Gentleman, co-created R – a statistical programming language now used by the majority of the world’s practising statisticians. It is hard to over-emphasise the importance of Ross’s contribution to our field. We named this lecture series in his honour to recognise his work and contributions to our field in perpetuity.

The 2019 Ihaka lecture series is now over. We will publish details of our 2020 series once they become available.

2019 Ihaka lecture series

Rise of the machine learners: Statistical learning in the computational era

Whether labelled as machine learning, predictive algorithms, statistical learning, or AI, the ability of computers to make real-world decisions is rising every year.

The 2019 Ihaka Lecture Series brought together four experts at the interface of statistics and computer science to discuss how computers do it, and how much we should let them.

Open source Machine Learning @ Waikato

Professor Bernhard Pfahringer from the Machine Learning research group at the University of Waikato discusses open-source Machine Learning software suites. He reflects on their design and their position in the current international Machine Learning landscape.

Deep learning: why is it deep, and what is it learning?

University of Auckland Professor Thomas Lumley discusses the rise of neural networks. He provides insight into how deep convolutional nets are structured and how they can be effective, but also why they are brittle and can fail in remarkably alien ways.

Algorithmic fairness: Examples from predictive models for criminal justice

Dr Kristian Lum from the Human Rights Data Analysis Group discusses the use of predictive models in the criminal justice system. Using examples from predictive policing and recidivism risk assessment she demonstrates how such models could perpetuate and potentially amplify data-encoded biases.

Statistical learning and sparsity

Professor Robert Tibshirani from Stanford University reviews the lasso method for high dimensional supervised learning and discusses some new developments in the area, including the Pliable Lasso, and post-selection inference for understanding the important features.

2018 Ihaka Lecture series

A thousand words: Visualising statistical data

A picture is worth a thousand words – or perhaps that should be a million numbers. The distillation of data into an honest and compelling graphic is an essential component of modern (data) science.

The 2018 Ihaka Lecture Series displayed the contributions of three experts across different facets of data visualisation.

Myth-busting and apophenia in data visualisation: Is what you see really there?

Plots of data are important tools for observing patterns, but it is easy to imagine patterns that may not exist. Using two protocols the Rorschach and the lineup, Professor Dianne Cook of Monash University describes some simple tools for helping to decide if patterns are real.

Making colour accessible

University of Auckland Associate Professor Paul Murrell investigates the 'BrailleR' package for R and its difficulties with colour. By making a mountain out of that molehill, Paul embarks on a daring Statistical Graphics journey featuring colour spaces, high-performance computing, Te Reo, and XKCD.

Visual trumpery: How charts lie – and how they make us smarter

With facts and truth increasingly under assault, the use of graphs, charts, maps and infographics have become popular in supporting all manner of spin. Identifying information from misinformation is an important skill for any citizen. Alberto Cairo from the University of Miami teaches some guiding principles on how people can become more critical and better-informed readers of charts.

2017 series

Statistical Computing in the Data Age

Statistics has become essential in the data age. We have an increasing ability to collect vast quantities of data, but often still struggle to make sense of it.

The 2017 Ihaka lectures aimed to highlight the important role that both statistics and computing play in this endeavour.

Expressing yourself with R

Hadley Wickham Chief Scientist at RStudio discusses Expressing yourself with R.

Interactive visualisation and fast computation of the solution path for convex clustering and biclustering

Genevera Allen, from Dobelman Family Junior Chair and Departments of Statistics and Electrical and Computer Engineering at Rice University, discusses clustering as a fundamental tool for exploratory analysis of big data.

Statistical computing in a (more) static environment

Ross Ihaka Associate Professor in the Department of Statistics at the University of Auckland discusses the spectrum of statistical computing systems from the dynamic to the very static.
