Awesome open data-centric AI

Open source tooling for data-centric AI on unstructured data

Data-centric AI (DCAI) is a development paradigm for ML-based solutions. The term was coined by Andrew Ng who gave the following definition:

Data-centric AI is the practice of systematically engineering the data used to build AI systems.

At Renumics, we believe DCAI is an important puzzle piece for building real-world AI systems that generate value. We like the following definition:

Data-centric AI means to improve training datasets systematically and iteratively by leveraging information from trained ML models.

Tools that can be efficiently used in day-to-day applications are the most important ingredient for the DCAI paradigm. This curated link collection is intended to help you discover useful open source tools for your data-centric AI workflows.

🔎 Scope

We include useful tools that have an open-source license and are actively maintained in this collection. All tools mentioned are useful for building DCAI workflows on unstructured data (e.g. images, audio, video, time-series, text).

We also collect workflow snippets into a data-centric AI playbook that show how typical tasks can be solved with open source tooling.

In order to keep a useful focus and to prevent duplicate work, we exclude some topics from this list such as tooling for tabular data, dedicated labeling tools, MLOps tooling as well as research papers. Please check out the further reading section to find awesome lists for these topics.
