Prof. Tim Kraska

Kraska's research focuses on building systems for machine learning , and using machine learning for systems. For example, with work on Learned Indexes we started to explore how we can enhance or even replace core systems components using machine learning models and early results suggest, that we are able to achieve significant performance improvements over state-of-the-art techniques and sometimes are even able to change the complexity class of certain algorithms. On the other hand, with Northstar we are exploring new user interfaces and infrastructure to democratize data science by enabling visual, interactive, and assisted data exploration and model building. One particular focus of our work is to not only make the model building process faster, but also safer by automatically preventing the user from common pitfalls.
