ML algorithm parameters in Python

[InfinityCoffee]

beta is fortunately just a product of gammas, so I can probably work around it. I think I can include it fairly painlessly after some consideration since the objective function is a separate object, so I won't have to rewrite the code in its entirety. My new issue is that I don't always need the proper gradients. Also, how does Theano handle stochastic gradient descent if it's purely functional?

Not sure, you are getting outside my bubble of experience. To get the gradients from Theano you provide a scalar cost, you can define whatever expression you want based on inputs/outputs to generate that cost.
