ReWork DL Boston 2015 – Day 1

So, day one of the ReWork Deep Learning Summit Boston 2015 is over.  A lot of interesting talks and demonstrations all round.  All talks were recorded so I will update this post as they become available with the links to wherever the recordings are posted – I know I’ll be rewatching them.

Following a brief introduction the day kicked off with a presentation from Christian Szegedy of Google looking at the deep learning they had set up to analyse YouTube videos.  They’d taken the traditional networks used in Google and made them smaller, discovering that an architecture with several layers of small networks was more computationally efficient that larger ones, with a 5 level (inception-5) most efficient.  Several papers were referenced, which I’ll need to look up later, but the results looked interesting.

Ex Machina – film review

While on my flight to Boston for ReWorkDL I watched Ex Machina the “must see” latest AI film. I’d been warned that it wasn’t very good by my husband (who’d just flown home the day before!) but I thought that since he’d already seen it, I’d better take the chance to watch it since it’s unlikely to be something we’d watch together in the future. If you haven’t seen it, then please be aware that this post does contain spoilers so read on with caution. Continue reading Ex Machina – film review

Machine intelligence – training and plasticity

I’m four weeks in to my new role and one of the threads of work I have is looking into machine learning and how this has advanced since my own thesis.  The current approach to machine intelligence is via learning networks where the data is abstracted: rather than recognising specifics about the problem, the algorithm learns the common elements of the problem and solution to match an input to the expected output, without needing an exact match.  Our brains are very good at this: from a very early age we can recognise familiar faces from unfamiliar ones and quickly this progresses to identification in bad light, different angles, when the face is obscured.  Getting machines to do the same has been notoriously difficult.

If you’ve been watching anything on Channel 4 recently you’ll have seen a trailer for PersonaSynthetics – advertising the latest home must-have gadget.  The ad itself is slightly creepy, despite the smiling family images, and the website supports this sterile AI view to an extent that some people have expressed concern over a genuine product being available.  It’s a fantastic ad campaign for their new series Humans, which in itself looks like it’d be worth a watch (there’s a nice trailer on the website), but it has raised again the issues around artificial intelligence, and how far should it go.

This is of particular interest to me as I am starting a new project in machine learning and, while my work isn’t going to lead to a home based automaton, there are some interesting questions to be considered in this area to ensure that we don’t end up making ourselves obsolete as a species.

How Old Robot – Well played

How Old example
Example of How Old Robot doing its thing

So, a few days ago, the internet had a new toy: How Old Robot – a very simple website where you can upload a photograph and it will guess your age and gender.  For many people the guess was about right, but there were some howlers, with very similar images being uploaded and giving age results differing by (several) decades!

The site doesn’t hide the fact that it’s a learning tool based on Microsoft’s facial recognition technology and is built on the Azure platform as an example of how quickly it is to build and deploy sites using Azure.  What started off as a quick demo from the Build conference soon became viral, with people all over the world loading their photos into the app and sharing the results on social media.  This is exactly what Microsoft wanted and they’ve been oh so clever with this and here’s why.

An academic professional

I’m three days in to my new role and, while there is some run of the mill development that I’m managing there’s also a very exciting project just starting that I’ll be taking from the very beginning based on a discussion I had with the CEO on my first day.

This new secret project means I’ve got to become an expert in Deep Learning and also all the changes in AI and since I wrote my own thesis.  I discovered very quickly that the way I knew was the “old way” and that machine learning has come on very considerably in a short space of time. So the past few days I’ve regressed into academic mode.
