Ruth Garcia – Data Scientist

Summary: Online advertising is an essential component of any business strategy. Every year, the investment on online advertising grows for mobile and web. To satisfy advertisers and increase ROI, many online ad publishers build their own ad serving platforms to manage and deliver ad inventory with flexibility and efficiently. As a consequence, the need of click prediction systems are an important aspect for the success of such systems. In this talk, I will introduce the importance of click prediction in ad manager from a publisher point of view. I will cover some of the challenges found when building click prediction models in this environment. I then explore some of the simplest algorithms used to tackle click prediction as well as some of the parameters that mostly impact performance.

Summary: Contextual multi-armed bandits for widget optimization. Mobile applications and websites are growing more complex than ever, with new graphics, functionalities and widgets being added every day. In this ever-growing space it is important to develop new approaches to surface the right content to the right users as many time as possible. While A/B test is a widely used and solid technique, it is not always viable when the number of possible choices is very large, hundreds or thousands of tests would be required to find the best option for each situation. This talk will firstly provide an introduction to the muti-armed bandit problem. Then, a practical comparison between bandits and classic A/B testing will be shown. Closing with a practical Bandit implementation at Skyscanner.
