Google Translate has developed an understanding of the meaning behind words so that it can translate directly from one language to another using the concepts behind phrases rather than a word by word translation.

This means it can be taught to translate from French to German and from German to Chinese and because it understands language at a conceptual level it can translate French into Chinese without going via German; it matches concepts not words.

Should we be worried by this latest revelation of a Neural Machine that has created its own internal language that nobody understands?

I’m not sure.

Imagine an algorithm to determine where to concentrate health-care research. If its inputs are biased towards one section of society, accidentally rather than by design, wouldn’t it develop a skewed view of the world?

Wouldn’t it favour some people over others?

Yes, but we already have a healthcare system that does that, don’t we? And, this could be less biased because it would be much more effective at using large volumes of data to determine the best outcome overall.

The difference is that in a world of “bias in, bias out” and opaque algorithms nobody, not even the creators, would know why it made the choices it did.

Maybe this is a price worth paying.

As this TechCrunch article says, “Neural networks may be complex, mysterious and little creepy, but it’s hard to argue with their effectiveness.”

Machine Learning Algorithms

Are machines that learn for themselves the stuff of nightmares or a vision of a wonderful utopian future?

The answer, of course, is neither.

We all know that technology is neutral, even though we forget a lot of the time. But there is that niggling doubt. What if they broke through the barrier and became sentient and intelligent?

It’s possible, but probably a long way off.

Artificial Intelligence and robots are hot topics for Science Fiction at the moment and I’m one of those who believe we should use fiction to help us imagine the future so we can be better prepared for it. Good or bad.

The more of us that have a basic understanding of how the tech works the richer the debate about how it’s used will be, so I was pleased to find some fun stuff from Google that starts to demystify machine learning.

Here’s an AI experiment that tests a neural network to see if it can guess what you’re sketching.

I’m rubbish at drawing but it guessed 2 out of my 5 doodles and as the designers say, “The more you play with it, the more it will learn.”

A day out with the robots

What do slipstream, near-future and climate-fiction authors have in common with the European Human Brain Project and the Bristol Robotics Laboratory?

In this case, creating stories to provoke debate between the scientific community and the public as part of the Bristol Lit Fest.

I’m a science-fiction writer – a near-future type rather than a distant planets type – and for some time I’ve been interested in the power of fiction, especially short fiction, to provoke debate. This often happens in the media when a popular science-fiction film portrays an apocalyptic future, but it’s less common to find a live event with real authors and real scientists.

As the Author in Residence for Virtual Futures, an organisation once described as “the Glastonbury of cyberculture”, I’ve been creating specially written five-minute stories for the past twelve months for their Salon events. These Salons bring together artists, philo-sophers, cultural theorists, technologists and fiction writers to consider the future of humanity and technology. They have introduced me to the new and exciting worlds of neurostimulation, prosthetic envy and bio-art – to name a few.

So, it was with a high level of excitement that I accepted an invitation from SilverWood Books to participate in their Bristol Lit Fest event, Science and Science Fiction: Versions of the Future.

And that’s why I found myself standing on the concourse of Paddington station one sunny Friday morning with two other authors, Allen Ashley and Jule Owen, and two social scientists from the Human Brain Project Foresight Lab. We were off to spend the day with the roboticists, taking a rare opportunity to look behind the scenes of cutting-edge tech, and ask whatever we wanted in the privacy of a closed meeting room.

We soon moved on from the inevitable pleasant introductions and small talk to meanderings about the future of politics, technology, the singularity and beyond. We became so enthusiastic that a nearby passenger joined us to bring his own perspective and generally join in the debate.

The day was shaping up very nicely!

When we arrived at the lab, Professor Alan Winfield gave us a whistle-stop tour and for the first time that day we all fell silent(ish).

I was fascinated, almost overwhelmed, by the robots he showed us, including robots that eat dead flies and excrete their waste, and an experimental swarm of them modelling how nanobots might enter your body and fix diseased cells. We also met Jules, the robot that mimics facial expressions – a particularly high point for fellow author Jule.

After the tour we moved on to the main event of the day: meeting the scientists to quiz them relentlessly about their work, and drawing every drop of inspiration possible in the process. They were very obliging and answered with enthusiasm and a wealth of information.

We heard all about different aspects of the lab’s work, ranging from medical, rehabilitation and emergency rescue robots through to morphological computation and bioenergy robots. We also ended up in a lively debate about robot ethics and the extent to which science fiction should be technology-optimistic. This is one of the perennial issues for this type of sci-fi writing and we decided to aim for something more in keeping with TV’s Black Mirror than a robot apocalypse.

Listening to the conversations on the train back, I’d say we achieved exactly what we set out to. My head was certainly buzzing with all sorts of ideas and the difficult part has been to settle on “the one”!

And now the stories are taking shape, getting ready for the festival. If we’ve done a good job these three five-minute stories will entertain the audience and provoke an informed debate with the scientists.

I’m sure the event will be as mind-stretching and inspiring as our visit to the robotics lab. If you live near Bristol, you should come along and join in!
