How do I crack the GSOC in the field of machine learning?

How do I crack the GSOC in the field of machine learning?

1. Working as a student at Google Summer of Code demands for your dedication and hard work.
2. To crack Google Summer of Code in the field of Machine Learning (or any other field), you must have a strong hold in that field. You must talk to the mentors in the organization and contribute to their code base which shows them your dedication and willingness to complete the project
3. Also, prior experience working in industry or some course projects where you have shown your potential in a particular field (Machine Learning for example) would be very helpful and would increase your chances in getting a project at Google Summer of Code.
