Face Recognition in Bars?

Each day seems to bring another application of face recognition technology. In one of the more recent news, a UK company has developed a face recognition-powered queueing systems for bars. A webcam above the bar films the crowd of people waiting to order their drinks and the system, named A.I. Bar, uses face recognition to keep track of a virtual queue: the barman sees on a screen who to serve next and a customer-facing screen above the bar shows numbers next to customers’ faces indicating their position in the queue.

Stories About AI

Last week I was talking with friends and the conversation turned to AI and how we feel its impact. Someone had heard the rumour that Facebook is listening to our conversations and showing us ads based on the content. Now, this particular rumour is not true. Besides questions of legality and creepiness, it is simply infeasible, even for a company as large as Facebook, to analyse the speech of all its users in real time. The necessary computational cost far exceeds any potential revenue that could be made from the resulting ads. This does not mean that the rumour is easy to kill, because there is always someone whose friend was once talking about visiting Australia and, lo and behold, they started seeing ads about Australia.

Selling Data to Amazon

I read the article thinking it would be just another bit of tech news, and yet for some reason my thoughts kept coming back to it. The story of the article is simple: Amazon is willing to pay people $10 to get access to their browsing histories. After giving the basic facts, the article then explores the idea of “buying” and “selling” data and the eventual implications of the seemingly simple offer by Amazon.

The Era of Mathematics

Two weeks ago the report ‘The Era of Mathematics’ was presented in the House of Lords by Professor Philipp Bond. The report examines the wider impact of mathematics on the economy and makes recommendations how to expand and facilitate knowledge exchange between mathematicians and the industry.

What is the Point?

Today the Guardian reported that a Polish man who went to the police to report an assault on his wife was questioned about his immigration status and handed over to immigration officials who detained him in Colnbrook Immigration Removal Centre. He has been in detention for the past two months.

There are genuine arguments for controlled immigration and “taking back cotrol of the border”. There is also merit in finding and deporting those who are in the country illegally. But what can possibly be the point of making life hell for those who have done nothing wrong? What purpose is served by casting the net of suspicion so wide that it causes collateral damage?
