Interview on AI with Ray Ram Thanni

December 7, 2019

I did an interview on high-level issues with AI for the Monash Blockchain Alliance, way back in 24th April 2019.  Its up on Youtube, finally.

Caitie on Einstein A Go Go

October 27, 2019

Caitie and Wray at 3RRR

Caitie Doogan, through her Twitter activies, got invited to talk on a science radio programme on 3RRR:  Einstein A Go Go – 27 October 2019 (our section starts at 25:15 in). Dr Krystal, Dr Ray & Dr Shane were the three scientists asking really relevant questions.  Caitie’s work is at the interface of applications and machine learning, so is far more accessible to the science public.  I came along for the ride, and discussed my work with Turning Point.

Turning Point and Monash at Google

July 31, 2019

Turning Point colleague, Sam Campbell, and I went to the Google AI Impact Challenge Accelerator event in London on 29th-31st July (see the video here, I get a brief shots at 0:14 and 0:20 and Sam gets an interview at 0:49).  Sam is the in-house data science person at Turning Point and a graduate of the Monash Master of Data Science programme.  I’ve been coaching him on modern text-mining with deep neural networks, and we’re starting to realise just how accurate the predictions can become.

Following our Launchpad event to San Francisco, the London event was an in depth technology review so we could help design our system.  We had a number of very clued-in Google experts supporting us in designing our architecture.  My systems and internet applications experience is over 20 years old, so I get the general ideas but don’t know the modern specifics!

AI Impact Challenge Accelerator Tech Sprint

All the teams at the London tech event, 31/07/19.

Lots the of AI Impact folks from Google attended and we all agreed the committment and support from Google was fabulous.  We’re in the top right, with Sam holding the “Turning Point” sign, me below him.

We learnt a lot about designing AI systems, and I saw some great tutorials on machine learning.  For human centred design, see PAIR: People and AI Research.  We spoke to contributors such as Di Dang and Roxanne Pinto.  Their guidebook is an absolute treasure trove.  The machine learning group told us about using the cloud, their AutoML, and they presented some fabulous tutorials on things like data wrangling.

AI suicide surveillance with Turning Point

Wray, Dan and Debbie at Google Launchpad, 15/05/2019

Along with Prof. Dan Lubman’s team at Turning Point, and funded through Google’s innovative AI for Social Good programme, I’ll be developing an AI system to accelerate “coding” (a form of content analysis) of ambulance records so we can understand the nature of suicide in Australia.   The local press has it so:

Google taps local addiction service to build AI suicide surveillance system

As the Google blurb says:

By using AI tools to analyze these records, Turning Point, a national center within Eastern Health, will uncover critical suicide trends and potential points of intervention to better inform policy and public health responses.

For us researchers, it means unifying a bunch technologies that I’ve been working in for a while like active learning, multi-label classification, multi-task learning and crowd-sourcing.  But most importantly, all these need to be placed in the context of​ doing accurate and properly monitored coding while at the same time trying to minimise costly expert (human) effort.  This is important stuff for NGOs and health organisations so we’re really excited by the application opportunities this can give us all.

In mid May, Dan Lubman, Debbie Scott and I flew off to Google’s Lauchpad Space in San Francisco to spend a week with other members of the programme for a bootcamp, to brainstorm about our project and get coaching from Google’s experts.  Google has a lot of other plans for us to, in terms of supporting the development, which we are very grateful for!  The Google advisors were fabulous.  They have all sorts of practical tech and AI knowledge, and a real diversity of start-up experts.

Dan, Debbie and I left the event with a whole different perspective on what we could do and what we should be doing initially.  We then set about the process of making change within Turning Point.  Turning Point is a sophisticated organisation working on mental health.  Yes, they’d integrated all sorts of computer systems and interfaces in their daily work, in fact a key reason behind their success to date, but we came away from the Google event realising just how much more we could do with AI.
