Agile and lean methodologies considered to be an opposite of through research. In this session, we will walk through the differences between agile definitions and data-science and try to decide whether they can long-live together. We'll start with why the can't - as trivial as it sounds - the tension between quality research and business stakeholders was never bolder. Then, we'll see methods and best practices to connect the two - Human-in-the-loop patterns and usage of active learning (for small-scale problems) and transfer learning (for more complicated ones) to allow more efficient research while really balancing time, business value and not compromising the research quality.
