Hello, Yesterday Elfarouk and I had the kick-off call for his gsoc project. A brief summary of the discussions:
The PR integrating Stan in the build system has been merged. Next is: - to finish up the cookbook PR (some small language fixes and adapting to new API); - as well as starting off the loss abstract class that hands the work to Stan. Further, there will be two subclasses implementing popular loss functions (squared and cross-entropy). These will also serve as an illustrative example for users about how to implement their own losses. Do not hesitate and ask away if anything is missing or not clear. Cheers, Fernando.
