Cost Sensitive Learning – A Hitchhikers Guide
Typically prediction is about getting the right answer. But many prediction problems have large and asymmetric costs for different types of mistakes. And often, the chance of making mistakes is exacerbated by training data imbalances. Cost-Sensitive Learning is the range of techniques for extending standard ML approaches to deal with imbalanced data and outcomes. Cost-sensitive…

Curtin HIVE Data Visualisation Presentation (2014)
IT was great fun presenting some novel business data visualisations on the impressive hardware at Curtin Hive. I just found this video from the 2014 presentation – at about 25 minutes, check out “The Matrix” on the 3m x 8m cylindrical display!

Continuous Intelligence at Thoughtworks Live
Mat Kelcey and I wrote on this talk together. Mat presented at the Sydney event (slides) and I presented at the Melbourne Event (different but same slides). We also had the pleasure of presenting alongside international guests Arif Wider and Sean Gustafson who shared their excellent DataDevOps manifesto (there’s a video from NDC too). I’d…

Byte Into It
I joined 3RRR’s Byte Into It on their 25th anniversary program to talk about ThoughtWorks’ technology innovation with Guide Dogs Victoria. You can watch the recording here (I’m on from 40 mins). Did someone say puppies? Image credit 3RRR.

Sky News Technology Behind Business
I appeared on the Sky News “Technology Behind Business” program to discuss business applications and adoption of AI and, most interestingly, whether we should fear a malicious super-intelligent AI. I said: rather, fear data leaks and the algorithmic corruption of public life.

Step Up on AI
I provided commentary on our need to step on AI capability and governance in Australia on this story in The Australian newspaper. I was quoted extensively in the article but I wrote a bunch more notes which might be of interest. Further Commentary In the regrettable case of the Knightscope security robot and the curious…

Reasoning About Machine Intuition
This talk discusses the resurgence of Machine Learning and neural networks from multiple digital perspectives, including: I chose to use “intuition” to distinguish ML’s capability for pattern recognition in narrow tasks from other descriptions of intelligence. Find slides here. Outline Machine intuition, ftw What just happened? So, what’s next? Designing products with intuition Developing technology…

Scaling Change
Once upon a time, scaling production may have been enough to be competitive. Now, the most competitive organisations scale change to continually improve customer experience. How can we use what we’ve learned scaling production to scale change? I recently presented a talk titled “Scaling Change”. In the talk I explore the connections between scaling production, sustaining…

Scaling Change Spoiler
When software engineers think about scaling, they think in terms of the order of complexity, or “Big-O“, of a process or system. Whereas production is O(N) and can be scaled by shifting variable costs to fixed, I contend that change is O(N2) due to the interaction of each new change with all previous changes. We could…

The life-changing magic of tidying your work
Surprise! Managing work in a large organisation is a lot like keeping your belongings in check at home. Get it wrong at home and you have mess and clutter. Get it wrong in the organisation and you have excessive work in progress (WIP), retarding responsiveness, pulverising productivity, and eroding engagement. Reading Marie Kondo’s The Life-Changing…
