Both are tricky subject and lot of cooking-like thinking (there are popular recipes, general rules, but in all practical cases to master it there is a lot of non-transferable experience and knowledge).

Some pointers:

At deepsense.io we are developing Neptune to facilitate that process (compare models, version-control them), here: https://go.neptune.deepsense.io (a public release in less that a month!).

Another resource - https://sigopt.com/, in the vein of Whetlab.

e.g. For NLP:

Disclaimer: they did share free trials with some of our students.

It looks interesting, and talk with these guys (including the author) on a conference (GPU Tech Conf in San Jose). However, for other much more transparent systems, I am kind of anxious to add a black box.

Especially as most of neural network tweaking go well beyond hyperparameter tweaking - one need to adjust architecture, make sensible cross-validation, good augmentation, etc.
