  • Intro to “Kupata”: Financial Accessibility in East Africa

    gates_logoAfrica, despite lagging behind in infrastructural development, is actually data rich. In 2010, of the 5 billion mobile phones in the world, 80% were in developing countries. East Africa is at the forefront of new technologies such as mobile payments, which are ubiquitous even for those in the lower socio-economic groups, with over 38m of Tanzanians (in a population of 49 million) having a mobile wallet. For a large majority of these 38m people, this is the only financial service that they have access to, banks and other financial institutions being a luxury even then 11m Tanzanians have no access to financial services at all.

    Brain-Computer Interface (BCI) Challenge Win for Duncan

    Today Dr Duncan Barrack gave his winning talk at the IEEE Neural Engineering Conference (NER2015) in Montpelier, France, after taking the first prize for the Kaggle competitition: “Brain-Computer Interface (BCI) Challenge”. The challenge used EEG data captured from study participants who were trying to “spell” a word using visual stimuli. As humans think, we produce brain waves that can be mapped to actual intentions. In the competition, competitors were given the brain wave data of people with the goal of spelling a word by only paying attention to visual stimuli.

    Duncan, a Mathematics Fellow on the Neo-demographics project at Horizon, won using a linear combination of two SVMs with linear kernels and different feature sets, and his interview at the event can be found here: Winner’s interview/
