Currently working in management consulting, I’m enjoying exploring data engineering, theoretical statistics and arduino at the moment. Education Doctor of Philosophy 2004-2008 Research focused on finding practical, but theoretically robust solutions for testing complex time series models over multiple dimensions (panel data). https://steph.ai/publications/publications/ Sun, 24 May 2020 00:00:00 +0000 https://steph.ai/publications/publications/ 2019 Robust and secure AI: A primer for the c-suite with M.

One thing we don’t teach very expliticly is understanding missing data or the toolkit available to do so. That’s what this post is about - it’s not technical, it’s not ‘fancy’, it’s the down-in-the-weeds basics that applied work needs to be done well. https://steph.ai/opensource/2019-ropensci-ozunconf/ Thu, 21 May 2020 00:00:00 +0000 https://steph.ai/opensource/2019-ropensci-ozunconf/ So 2019 was … big. And I didn’t touch the blog all year. But that didn’t mean there was no open source happening. I was the program chair of the ROpenSci OzUnconference. I did blog about what an amazing team we had and the extraordinary projects we put together. You can read about that on the rOpenSci blog in detail. And when I said it was a tough time for Australia back in December … hoo boy did I have no clue. https://steph.ai/opensource/bayes-frequentist/ Thu, 21 May 2020 00:00:00 +0000 https://steph.ai/opensource/bayes-frequentist/ Another of my beloved projects that got very little attention last year. Are new years’ resolutions in late May allowed? The Bayesian and the Frequentist is the brainchild of John Ormerod, Associate Professor of Stats @ University of Sydney and myself. What happens when you put together a corporate data scientist and an academic statistician. We’re not really sure what to call it. But it’s definitely something I’m going to get back into this year. https://steph.ai/post/ggplot2-tutorial/ Sat, 22 Sep 2018 00:00:00 +0000 https://steph.ai/post/ggplot2-tutorial/ Should you bother with ggplot? Switching to data visualisation through code is a huge ask. Is this how you feel about code? How I used to feel about code. This is a perfectly normal reaction. But..! Can you do this? You can do this. Then you’re already writing code. Maybe you don’t think about yourself as a programmer … yet! https://steph.ai/post/the-keys-to-the-kingdom/ Sun, 10 Jun 2018 00:00:00 +0000 https://steph.ai/post/the-keys-to-the-kingdom/ I started a new job last week- here I am working on transport and GIS! As it turns out, both transport and GIS are awesome. But how do you get up to speed really, really quickly? You ask for help. Asking for help In return, I was given the keys to the kingdom - people to follow, blog posts to explore, books to read, offers of help. This community is amazing. https://steph.ai/opensource/beyond-syntax-towards-subculture-on-the-power-and-potentiality-of-deep-open-source-communities/ Thu, 17 May 2018 00:00:00 +0000 https://steph.ai/opensource/beyond-syntax-towards-subculture-on-the-power-and-potentiality-of-deep-open-source-communities/ Introduction R is a growing, vibrant programming language. Originally created by Ihaka and Gentleman in the 1990s, what was a niche experimental language is now in mainstream usage across many disciplines and domains (Ihaka, 1998). One thing that Ihaka and Gentleman may not have intended at the time was the fact that R is no longer just a programming language. Users of R are developing into a distinct programming subculture at the intersection of multiple domains. https://steph.ai/post/cpa-emerging-leaders-conference/ Thu, 17 May 2018 00:00:00 +0000 https://steph.ai/post/cpa-emerging-leaders-conference/ I had the opportunity to talk at the CPA Emerging Leaders Conference today in Melbourne, then again next week in Sydney. It was a great crowd with a really interesting mix of perspectives. I was talking about Creating data driven value and insights, which was aimed at showing an already very data literate group of people (accountants!) how to get started with data driven thinking. My thoughts on getting started come down to five things: https://steph.ai/post/data-driven-by-design/ Mon, 30 Apr 2018 00:00:00 +0000 https://steph.ai/post/data-driven-by-design/ The data revolution is upon us! Or at least that’s what someone with a snappy grasp of copy-editing and a mandate for clicks would say. There’s a common misperception that’s out there in the data world that only some of us know how to be data driven. Only some of us have our data driving licenses and can get behind the wheel. This is manifestly false. Even if you don’t know R or Python or any other part of the common data science toolkit (yet), there are things you can do and start to think about today as you begin to embrace the idea of data-driven decision making. https://steph.ai/publications/speaking-engagements-2018/ Fri, 27 Apr 2018 00:00:00 +0000 https://steph.ai/publications/speaking-engagements-2018/ 2018 May Emerging Leaders Conference: Melbourne, CPA Australia Creating data driven value and insights Thursday 17 May.

In consulting, the data science workflow is also critical, but it’s wrapped up with some extra management challenges. In addition to code and data, there’s a series of documents, people and timing to manage. https://steph.ai/post/new-site/ Thu, 26 Apr 2018 00:00:00 +0000 https://steph.ai/post/new-site/ There’s some big changes going on in my professional life, so it was time for a change. This is my new blog - my previous work is hosted over at Rex Analytics. Welcome! https://steph.ai/post/packetiser/ Thu, 26 Apr 2018 00:00:00 +0000 https://steph.ai/post/packetiser/ If you’re a rural data scientist, then sooner or later you’ve had to move a big file to the cloud or back. That’s a world of pain right there. If you know anything about how information is transmitted via the internet, you know that files are broken into packets, sent, then reassembled on the other side. If packets go missing, the computer requests resends until the file is fully assembled, or until the system times out. https://steph.ai/publications/upcoming-engagements/ Thu, 26 Apr 2018 00:00:00 +0000 https://steph.ai/publications/upcoming-engagements/ 2018 May Emerging Leaders Conference: Melbourne, CPA Australia Creating data driven value and insights Thursday 17 May.
