Evidence in our AI future

Generated handwriting from the team at UCL

If you’ve been following this blog you’ll know that there have been great advances in the past few years with artificial image generation, to the stage where having a picture of something does not necessarily mean that it is real.  Image advances are easy to talk about, as there’s something tangible to show, but there have been similar large leaps forward in other areas, particularly in voice synthesis and handwriting.

Artifical image creation takes another step forward in advertising

Dove's "perfect mum" image generated by AI
Is there the perfect mum? Dove’s Aimee is AI’s created image  based on what the media think she should be (c) Dove

Earlier this month, Dove launched their new baby range with another of their fantastic adverts challenging stereotypes and questioning is there a “perfect mum”.  As a mum myself I can relate to the many hilarious bloggers1 who are refreshingly honest about the unbrushed hair, lack of make-up, generally being covered in whatever substances your new tiny human decides to produce, and all other parenting frustrations.  I’m really pleased that there are lots of women2 out there challenging the myths presented in the media – we don’t all have a team to make us beautiful, nor someone photo-shopping the results to perfection, and the pressure can be immense.  This is where Dove’s campaign is fantastic.  Rather than just creating a photoshoot with a model and doctoring the results, the image is actually completely artificial, having been generated by AI.

Submitting evidence to parliament committees

(c) Parliament committee on Science and Technology

I love the fact that here in the UK everyone can be involved in shaping the future of our country, even if a large number of individuals choose not to and, in my eyes, if you don’t get involved then you don’t have the right to complain.  While this is most generally applied to the election of our representatives from local parish councils to our regional MPs (or actually standing yourself)1 there are also a lot of other ways to be involved.  In addition to raising issues with your local representative, parliament has cross bench committees that seek input from the public and to help create policy or consider draft legislation.

Our elected parliament is not made up of individuals who are experts in all fields.  Even government departments are not necessarily headed by individuals with large amounts of relevant experience.  It is critical that these individuals are informed by those with the experience and expertise in the issues that  are being considered.  Without this critical input, our democracy is weakened.

Choosing a Laptop for Deep Learning Development

Confusion matrix
The matrix, well a matrix… A confusion matrix for a 60 class network running on the Dell XPS laptop

If you’re starting out in deep learning and would prefer a laptop over a desktop, basic research will lead you to a whole host of blogs, Q&A sites and opinions that basically amount to “don’t do it” and to get a desktop or remote into a server instead.  However, if you want a laptop, whether this is for college, conferences or even because you have a job where you can work from anywhere, then there are plenty of options available to you.  Here I’ll lay out what I chose and why, along with how it’s performing.

True Type Fonts in LaTeX: a brief guide

Adding new fonts to LaTeX doesn’t have to be painful…

One of the things I love about \LaTeX is how customisable it is.  Separating content from design a long time before web design cottoned on to this.  However, out of the box, \LaTeX comes with very limited fonts and most people just use these defaults, mainly because setting up other fonts isn’t as easy as it should be.

One of the great things about drawing diagrams in \LaTeX is that the fonts match, it’s always a little jarring to my eye when I see papers with a mismatch between diagrams and main text.  However, sometimes you just can’t control what’s in your diagram or you want something a little more modern than Times New Roman for whatever you’re putting together.

So how do you go about doing this?  Like most things, the answer is “it depends”… let’s start with an assumption that you’re starting from scratch and if you’re already a few steps down the process then that’s just less work for you to do 🙂 Continue reading True Type Fonts in LaTeX: a brief guide

Algorithmic transparency – is it even possible?

Could you explain to a lay person how this network makes decisions?

The Science and Technology Select Committee here in the UK have launched an inquiry into the use of algorithms in public and business decision making and are asking for written evidence on a number of topics.  One of these topics is best-practise in algorithmic decision making and one of the specific points they highlight is whether this can be done in a ‘transparent’ or ‘accountable’ way1.  If there was such transparency then the decisions made could be understood and challenged.

It’s an interesting idea.  On the surface, it seems reasonable that we should understand the decisions to verify and trust the algorithms, but the practicality of this is where the problem lies. Continue reading Algorithmic transparency – is it even possible?

Internet of Things: Making a Smart Home

The hive thermostat, it’s a lot prettier than my old one.

I grew up reading and watching Sci-Fi. As a child with an Acorn Electron, the idea of smart interactable devices seemed far future rather than near future. I loved the voice interactivity and things ‘just working’ without needing to be controlled. When I got my Echo dot last year, I knew this would be the start of a journey to upgrade my house to a SmartHome and truly be part of the Internet of Things. It’s been four months now and I’ve got a setup with which I’m pretty happy.  Here’s what I chose and why… Continue reading Internet of Things: Making a Smart Home

MST210 – Lack of routine has consequences

After the lack of focus I’d had studying for M208, I was adamant that with MST210 I’d get into a routine and stay on top of the work regardless of what else life through at me.  This worked pretty well in October and November.  I did the work during my commutes, approximately 3-4 hours a day, even if I had to sit on the floor of a train carriage or find a dusty corner of Paddington while waiting for a delayed train.  All was going well.  At the end of November I began the process of changing jobs and, because of the nature of my work, was put on garden leave for three months.  Suddenly I wasn’t confined on trains for about one seventh of every weekday.  This is where my whole routine broke down. Continue reading MST210 – Lack of routine has consequences

Review: What If? Serious scientific answers to absurd hypothetical questions

What if? From the creator of xkcd

It’s been a while since I read a physical book.  Most of my reading these days is done on the kindle and, while I still have physical text books for my maths degree, I have a lot of books just waiting to be read.  What If? by xkcd creator Randall Munroe is one of these.  I was given this as a present a few years ago and, despite my initial excitement (having been a reader of xkcd since about comic 17212) the book had sat on my bedside table under the kindle but just above the half-read “Sagas of the Icelanders” that I’d bought on my honeymoon.  Last week I picked it up and started reading.  I read just under half in that first sitting and then two days later finished it.  I wish I’d read it the day it was given to me.

Diagrams with LaTeX – easier than you might think

Diagrams like this are easy to do in LaTeX

I’ve written before about the power of literate programming, using \LaTeX to create reports when code runs.  It’s fairly simple to combine this with the graphical drawing packages to create impressive graphs and figures on the fly.  A lot of academics I’ve spoken to have shied away from using \LaTeX for drawing, despite being very proficient with the textual layout.  Similarly, a lot of students on the OU Mathematics degree write up all of their assignments in \LaTeX but drop in hand drawn graphs and diagrams.  Just like anything else in \LaTeX, once you get your head around how it works, it’s actually not that difficult to create very complex structures.
