orion 0.1.7

Asynchronous [black-box] Optimization

Oríon is an asynchronous framework for black-box function optimization.

Its purpose is to serve as a meta-optimizer for machine learning models and training, as well as a flexible experimentation platform for large scale asynchronous optimization procedures.

Core design value is the minimum disruption of a researcher’s workflow. It allows fast and efficient tuning, providing minimum simple non-intrusive (not even necessary!) helper client interface for a user’s script.

So if ./run.py --mini-batch=50 looks like what you execute normally, now what you have to do looks like this:

orion -n experiment_name ./run.py --mini-batch~'randint(32, 256)'

Check out user’s guide-101 for the simplest of demonstrations!

Features

As simple and as complex you want

• Simple and natural, but also explicit and verbose, search domain definitions
• Minimal and non-intrusive client interface for reporting target function values
• Database logging (currently powered by MongoDB)
• Flexible configuration
• Explicit experiment termination conditions
• Algorithms algorithms algorithms: Skopt’s bayesian optimizers are at hand without writing. Random search is the default. only a single line of code.
• More algorithms: Implementing and distributing algorithms is as easy as possible! Check developer’s guide-101. Expect algorithm plugins to pop out quickly!
• Came up with an idea? Your intuition is still at play: Help your optima hunter now by a command line interface.
• And other many more already there or coming soon!

Installation

Install Oríon by running:

pip install orion
