Introduction to Code Base and Work flow

[D-K-E]

Hi people,
I saw the project and i would like to contribute.
I would like to know if there is any area you want me to focus. I had seen that there is a work flow established for the team. It would be great if you can make it a wiki or publish it somewhere so that i can look at it. I've seen that some ml algorithms are being worked on, maybe i can help with some of the implementations, maybe a linear regression, or pca module ? If you are interested, i would like to know how you pre-process your features, or better how is the training data is structured.
