You say ‘po-tay-to’ – next steps for voice interface

After seeing the first Iron Man film, many people probably wished they had access to an all-powerful suit that could fly. Not me though, what I wanted was Jarvis, the voice-activated personal assistant who would act on my every request and perhaps even quip back at me. In 2008, when Tony Stark made his first […]

Explain yourself machine

According to Stephen Hawking, artificial intelligence will be “either the best, or the worst thing, ever to happen to humanity”. The recent breakthroughs in artificial intelligence are largely due to developments in machine learning. However, one of the key challenges of machine learning is that when ‘the machine’ gets it wrong, it is very hard […]

Correlation or cause – real sensors for the age of fake news?

The energy grid is a wide and complex system with many inputs and a huge number of outputs and consumers. Demand is fluctuating all the time, yet the information coming back from consumers may be months out of date. It’s possible to measure the inputs to the system at the distribution side, but that gives […]

You ain’t got soul – why analogue sounds better

Clearly real instruments have analogue outputs (especially the voice), yet nearly all music is stored and sold digitally. The recording process is ‘perfect’ after decades of development, the human ear is well understood – yet vinyl records are coming back. Analogue recording requires multiple types of signal conversion – from pressure waves to electrical signals […]

Yesterday was not Pi day – it’s 22nd July, honest!

OK, so the world celebrated International Pi day yesterday and I sat thinking that I should really write something for our social media channels on this, but try as I might the muse was not upon me, I could not come up with anything that had not already been said. I received the expected promotional […]
