This week I was surprised to learn that I won the Kaggle Social Networks competition!
This was a bit different from other Kaggle competitions. Typically, a Kaggle competition will provide a large set of data and want to optimize some particular number (say, turning anonymized personal data into a prediction of yearly medical costs). The dataset here intrigued me because it’s about learning from and reconstructing graphs, which is a very different kind of problem. In this post, I’ll discuss my approach and insights on the problem.
