Steppy

What is Steppy?

1. Steppy is a lightweight, open-source, Python 3 library for fast and reproducible experimentation.
2. Steppy lets data scientist focus on data science, not on software development issues.
3. Steppy's minimal interface does not impose constraints, however, enables clean machine learning pipeline design.

What problem steppy solves?

Problems

In the course of the project, data scientist faces two problems:

1. Difficulties with reproducibility in data science / machine learning projects.
2. Lack of the ability to prepare or extend experiments quickly.

Solution

Steppy address both problems by introducing two simple abstractions: Step and Tranformer. We consider it minimal interface for building machine learning pipelines.

1. Step is a wrapper over the transformer and handles multiple aspects of the execution of the pipeline, such as saving intermediate results (if needed), checkpointing the model during training and much more.
2. Tranformer in turn, is purely computational, data scientist-defined piece that takes an input data and produces some output data. Typical Transformers are neural network, machine learning algorithms and pre- or post-processing routines.

Roadmap

⏩ At this point steppy is early-stage library heavily tested on multiple machine learning challenges (data-science-bowl, toxic-comment-classification-challenge, mapping-challenge) and educational projects (minerva-advanced-data-scientific-training).

⏩ We are developing steppy towards practical tool for data scientists who can run their experiments easily and change their pipelines with just few manipulations in the code.

Related projects

We are also building steppy-toolkit, a collection of high quality implementations of the top deep learning architectures -> all of them with the same, intuitive interface.
