Python Machine Learning Experts I'd like to apply some of the more complex supervised machine learning techniques in python - deep learning, generalized addative models, proper implementation of regularization, other cool stuff I dont even know about, etc.

Any recommendations how I could find expert ML folks that would like to collaborate on projects?
You could try some competitions from kaggle.

Data Science courses from Coursera, edX, etc also provide forums for discussion.

Linkedin or freelance sites could be other possibilities.
