If you follow my posts on AI (here and on other sites) then you’ll know that I’m a big believer on ensuring that AI models are thoroughly tested and that their accuracy, precision and recall are clearly identified. Indeed, my submission to the Science and Technology select committee earlier this year highlighted this need, even though the algorithms themselves may never be transparent. It was not a surprise in the slightest that a paper has been released on tricking “black box” commercial AI into misclassification with minimal effort. Continue reading Fooling AI and transparency – testing and honesty is critical
It’s not often I get chance to play computer games anymore. The precious few hours I get to myself most days are usually filled with trying to catch up on my OU study1. So when I do choose a game, it has to be something immersive, where I make a difference. I loved Fable when it first came out and having finished Fable 3 recently (well behind the rest of the community I know!) I was looking for something new. A game I could play for ten minutes or an hour, something that I could be absorbed into and something where it didn’t matter if I didn’t play it for a couple of weeks. My wonderful husband bought Oxenfree for me on the XBox (also available on Steam) and I was hooked from the beginning. Continue reading Review: Oxenfree
One of the toys that’s been advertised heavily in the UK this year for Christmas has been Cozmo with it’s “Big Brain, Bigger Personality” strapline. I got one last year and it was a great present. Let’s get this out there. Cozmo is relatively expensive. For about £1501 there are a lot of other things you might prefer to buy for a child (or an adult) for what is, on the surface “just a toy”. If you treat it as such then maybe it’s not the right thing for you, but viewing Cozmo as a simple toy is far less than he deserves. He is a lot of fun to play with, and the more you play with him, the more he begins to do. Continue reading Cozmo – a good present?
In the past few weeks my social feeds have been littered with articles citing “Hinton’s latest breakthrough” in AI: capsule networks. Like most people in the field, I make sure I read up on what’s new, and I’m yet to see the paper‘s first author Sara Sabour, get credit for her work in all of the tertiary reviews.
For those who aren’t in academia, there is a distinct order to the names on published papers either by contribution or alphabetically. For contribution, the first author is the one who actually did the research, the last author is the person who runs the lab/department and any other names are listed in order of contribution. Occasionally you will see notes that authors contributed equally. Some subject or countries list names alphabetically, but this is not the case for this paper published on arxiv. Continue reading Credit where it’s due in AI – capsule networks
I get very tired of the clickbaity journalism hyping up minor advances in AI, making news stories out of nothing or even the ones for those in the industry. You know the type: “Facebook AI had to be shut down”, “Google creates self learning AI”.
I demystify a lot of these when I’m asked about them – technology should be accessible and understandable and I deplore the tendency of those seeking to get article hits by over-egging with misleading headlines. What amused me over the weekend was that an AI not beating a human was a news story where the AI was “trounced”. Continue reading When did AI not being as good as humans be a news item?
Following on from the meetup talk I gave on building your own personal brand, I’ve been asked a few questions about speaking at events and being a panellist. I felt it would be a good idea to write a few posts on this for reference. This one is particularly about panel sessions. Continue reading Being a Panellist at a Tech Talk
There’s been a lot in the news recently about how Oxford and Cambridge are failing young people who are educated by the state system and how they perpetuate the elitist machine that runs the UK. As ever, I’m frustrated with the polarisation of the argument perpetuated by the media, which boils down to “it’s fine” and “everything is broken”, which no room for focussing on the nuances of the problems. As a state school student who went to Oxford1, I thought I’d weigh in with my own experiences and where I believe the issues are. Continue reading The Oxbridge Myth
One of the things I’ve enjoyed least about my OU Maths journey so far has been group theory. I ploughed through whole swathes of M208 applying the techniques and not really seeing the relevance1 I found group theory and the proofs related to it tedious. Mainly because I was proving something that was “obvious”. However, I’ve always had a healthy acceptance of partial learnings – knowing that if I was being taught a technique then there was a reason for it. Two years later and that reason finally hit me. Continue reading M337: Group theory becomes relevant
I love choose your own adventure books. I read The Warlock of Firetop Mountain when it was first released and then pretty much every single Fighting Fantasy book released after it1. I also credit one of these books with improving my French reading and vocabulary after finding “La Malediction du Pharaon” in a charity shop2. One of the themes that run through all these books is your statistics: stamina, skill, and luck3. As you use these abilities they deplete. Use them too much and you will likely come to a sticky end in the books.
Real life is pretty similar, both mentally and physically. Continue reading Determination and Stamina: valuable stats but they’re not infinite
I gave myself a birthday present again this year, by registering for another 60 points worth of Open University maths modules. I’d put it off for quite a while as I couldn’t decide which level three modules I wanted to do most and also in which order. The only fixed option was “The quantum word” which was only available once I’d completed1 60 points worth. This left me with a choice of 3 modules from 4 other interesting options. Sadly, I discovered (thanks to a comment) that the pure maths module I intended to do was a 60 point module, meaning I either had to lose that from my choice or two of the modules I was really wanting to do. In the end, pure mathematics lost out and I’m committed to four 30 point modules. Continue reading OU level 3: Complex numbers and stochastic dynamics
