Using Open Data & Machine Learning !

Before I was not convinced that Open Data brings more value to my project. Lately, just using Open Data, I am able to build an efficient model to predict dengue rate in Brezil with Least Angle Regression algorithm. To do so, we used meteo (wind, temperature, precipitation, thunder / rain rates, ...), altitude, localisation, urbanization, twitter / wikipedia frequency and custom variables (mostly lag).
