1) Data Science: For Fun and For Profit
Data Science is relatively new, but the ideas and techniques that form the underpinnings for this evidence-oriented discipline have a solid foundation in hundreds of years of scientific development. In order to understand the new science of data, one must first understand the science of science.
The Scientific Method, the unintended effects of repeated significance testing and Simpson's paradox: this talk will focus on the practical applications of the theoretical constructs that lie at the heart of Data Science; and expand on some potential pitfalls of statistical analysis that you are likely to encounter when venturing into the field.

2) Topic Modelling on Travel Data.
Booking.com collects millions of diverse endorsements from its users, for example, London endorsed for Shopping, Brussels for Chocolate, Athens for Museums and Barcelona for its nightlife. These endorsements are organised using Latent Dirichlet Allocation to a set of topics and used to personalise the Email-Marketing campaign of Booking.com. The results from experiments on more than 40 million unique users demonstrate the conceptual value of the discovered topics.
