0 Have your say The public perception of stock exchanges remains little changed since the Big Bang deregulated the financial markets. Anytime a trading floor is depicted in a film or TV series, you can expect to see a group of men frantically waving their arms and shouting at a bank of screens showing the ups and downs of share prices. But the reality is different. Around three-quarters of exchanges on the NYSE and Nasdaq are now carried out by algorithms - computer programs designed to follow a particular set of rules - and not human traders.The last stock exchange in Scotland closed in 1973. As recently as half a century ago, there were four operating north of the Border.Now any Scot looking to dabble in the markets only requires a laptop or smartphone and some capital ready to invest. Any number of online services - from Nutmeg to Moneyfarm - can help you build a broad portfolio without the need to speak to anyone on the phone.Machine learning, which broadly refers to how … [Read more...] about How machine learning is transforming the stock exchange

Picture: AFP By Nomi Byström Whistleblower Christopher Wylie’s revelations on the exploiting of voters’ data have been heavyweight not once but twice. In the European Union too, personal data of millions was harnessed to influence choices at the ballot box: to vote for leaving the European Union in the Brexit referendum of 23 June 2016. As for voters themselves, they were oblivious to what was done with their information. But Wylie’s insights also affirm how truth can be stranger than fiction. Perhaps this is also the reason why, despite attempts to draw attention to the abuses of data for years, scholars, journalists and civil society organisations have had an uphill struggle to make their voices heard. The March revelations did not come out of the blue. Rather, they have brought much-needed attention to what has been known about shady and nothing short of unlawful campaigning activities. Violating the UK Data Protection Act, enormous, politically … [Read more...] about Personal data was weaponised against democracy in the EU – and can be again
IF LANDING in soggy Britain after a holiday in the sun is not enough to sap the soul, spending an hour queuing at border control does the trick. Eyn, a British startup, hopes to speed things up with a phone app. Passengers use the app to take a picture of their passport, then scan the chip which contains their facial biometrics. Finally, they take a selfie, to ensure the two faces align. Tapping their phone on electronic gates at the airport is then all that’s required. Eyn reckons such gates might not even be needed, if sensors prove capable of reading passengers’ faces instead. The firm is in talks to test its technology at the border. Govtech, or digital technology to improve public services, is a relatively new field in which Britain is busy. The amount of venture capital invested in govtech projects in Britain is on a par with that in the rest of Europe combined, according to PwC, a consultancy. Investment in the industry could grow from £6.6bn ($9.2bn) last year … [Read more...] about The apps that put public services in citizens’ pockets
We are witnessing just the beginning of the artificial intelligence (AI) era. The computer program AlphaGo defeated the world’s top player in the complex Chinese board game of Go for the last time in May 2017. The program had run out of human competition. Instead, its developers designed AlphaGo Zero to simply play against itself without the aid of any historical game data. AlphaGo Zero taught itself how to beat all versions of AlphaGo in 40 days. People have been playing Go for millennia. And yet all the human wisdom accrued during those countless hours of competition across the continents and throughout history turned out to be no rival to an AI program with 40 days to itself. And AI’s footprint is not limited to board games. Its imprint can be seen in countless industries and professions, from finance, to medicine, to accounting. JPMorgan’s COIN program performed 360,000 hours of finance-related work in a few seconds. An AI program at the University of Nottingham … [Read more...] about What’s the difference between artificial intelligence, machine learning and deep learning?
