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
```shell
pip install randopt
```
# Usage
```python
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](https://github.com/seba-1511/randopt/wiki/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](https://github.com/seba-1511/randopt/wiki/evolutionary) and [GridSearch](https://github.com/seba-1511/randopt/wiki/grid_search) classes.
For more info on hyper-parameter optimization, refer to the [Optimizing Hyperparams](https://github.com/seba-1511/randopt/wiki/Optimizing-Hyperparams) tutorial.
