Neither of you have looked at the data yet? There is no way to make any sense of what the data actually represents.
This is a pure machine learning contest, no financial background required. I’m an astronomer, others here are biologists or geologists, and for us, this competition is perfect to practice some machine learning techniques on a really difficult problem. If this dataset was similar to any other data set provided by places like Quantopian, then a lot of people would not even attempt to take part because they don’t have the financial training or background.
We don’t submit models to Numerai either. We only submit our predictions. Most of the people here don’t do this as a day job, we do it for a chance to learn some machine learning techniques that we can use in our day jobs. This is a side project for most that take part.
