Lale is a Python library for semi-automated data science.

Lale makes it easy to automatically select algorithms and tune

hyperparameters of pipelines that are compatible with

[scikit-learn](https://scikit-learn.org), in a type-safe fashion.  If

you are a data scientist who wants to experiment with automated

machine learning, this library is for you!

Lale adds value beyond scikit-learn along three dimensions:

automation, correctness checks, and interoperability.

For *automation*, Lale provides a consistent high-level interface to

existing pipeline search tools including Hyperopt, GridSearchCV, and SMAC.

For *correctness checks*, Lale uses JSON Schema to catch mistakes when

there is a mismatch between hyperparameters and their type, or between

data and operators.

And for *interoperability*, Lale has a growing library of transformers

and estimators from popular libraries such as scikit-learn, XGBoost,

PyTorch etc.

Lale can be installed just like any other Python package and can be

edited with off-the-shelf Python tools such as Jupyter notebooks.

The name Lale, pronounced *laleh*, comes from the Persian word for

tulip. Similarly to popular machine-learning libraries such as

scikit-learn, Lale is also just a Python library, not a new stand-alone

programming language. It does not require users to install new tools

nor learn new syntax.

Lale is distributed under the terms of the Apache 2.0 License, see

[LICENSE.txt](https://github.com/IBM/lale/blob/master/LICENSE.txt).

It is currently in an **Alpha release**, without warranties of any
