Streamlined machine learning experiment management.
Project description
randopt is a Python package for machine learning experiment management, hyper-parameter optimization, and results visualization. Some of its features include:
- result logging and management,
- human-readable format,
- support for parallelism / distributed / asynchronous experiments,
- command-line and programmatic API,
- shareable, flexible Web visualization,
- automatic hyper-parameter search, and
- pure Python - no dependencies !
Installation
pip install randopt
Usage
import randopt as ro
def loss(x):
return x**2
e = ro.Experiment('myexp', {
'alpha': ro.Gaussian(mean=0.0, std=1.0, dtype='float'),
})
# Sampling parameters
for i in xrange(100):
e.sample('alpha')
res = loss(e.alpha)
print('Result: ', res)
e.add_result(res)
# Manually setting parameters
e.alpha = 0.00001
res = loss(e.alpha)
e.add_result(res)
# Search over all experiments results, including ones from previous runs
opt = e.minimum()
print('Best result: ', opt.result, ' with params: ', opt.params)
Results Visualization
Once you obtained some results, run roviz.py path/to/experiment/folder
to visualize them in your web browser.
For more info on visualization and roviz.py
, refer to the Visualizing Results tutorial.
Hyper-Parameter Optimization
To generate results and search for good hyper-parameters you can either user ropt.py
or write your own optimizaiton script using the Evolutionary and GridSearch classes.
For more info on hyper-parameter optimization, refer to the Optimizing Hyperparams tutorial.
Documentation
For more examples, tutorials, and documentation refer to the wiki.
