About Me

Danny Bickson: 6 years ago, along with my collaborators at Carnegie Mellon University, I have started the GraphLab large scale open source project, which is a framework for implementing machine learning algorithms in parallel and distributed settings. When the project became popular, we have decided to raise money to expand the project and provide an industry grade solution. Specifically I wrote the award wining collaborative filtering toolkit to GraphLab which is widely deployed today, and helped us win top places at ACM KDD CUP 2011, ACM KDD CUP 2012 among other competitions.
