An easy-to-use machine learning toolbox for estimating models, distributions, and functions with context-specific parameters.
Context-specific parameters:
- Find hidden heterogeneity in data -- are all samples the same?
- Identify context-specific predictors -- are there different reasons for outcomes?
- Enable domain adaptation -- can learned models extrapolate to new contexts?
## Quick Start
### Installation
```
pip install contextualized-ml
```
Take a look at the [easy demo](docs/models/easy_regression.ipynb) for a quickstart with sklearn-style wrappers.
### Build a Contextualized Model
```
from contextualized.easy import ContextualizedRegressor
model = ContextualizedRegressor()
model.fit(C, X, Y)
```
### Predict Context-Specific Parameters
```
model.predict_params(C)
```
See the [docs](https://contextualized.ml/docs) for more examples.
### Important links
- [Documentation](https://contextualized.ml/docs)
- [Pypi package index](https://pypi.python.org/pypi/contextualized-ml)
## Contextualized Family
Context-dependent modeling is a universal problem, and every domain presents unique challenges and opportunities.
Here are some layers that others have added on top of Contextualized.

Contextualized ML was originally implemented by [Caleb Ellington](https://calebellington.com/) (CMU) and [Ben Lengerich](http://web.mit.edu/~blengeri/www) (MIT).
Many people have helped. Check out [ACKNOWLEDGEMENTS.md](https://github.com/cnellington/Contextualized/blob/main/ACKNOWLEDGEMENTS.md)!
