CodaLab is an open-source web-based platform that enables researchers, developers, and data scientists to collaborate, with the goal of advancing research fields where machine learning and advanced computation is used. CodaLab helps solve many common problems in the arena of data-oriented research through its online community, where people share worksheets and participate in collaborative competitions.

Immutable experimentation that ensures reproducibility

Today’s data-driven research and development is stymied by an inability of scientists and their collaborators to easily reproduce and augment one another’s experiments. CodaLab addresses this problem by providing a cloud-based virtual “workbench,” where computer scientists can conduct data-driven experiments quickly and easily.

Experiments can then be easily copied, reworked, and edited by other collaborators in order to advance the state-of-the-art in data-driven research and machine learning. Conferences such as ACL 2016 encourage the use of CodaLab Worksheets for submission of software resources with papers. Do you want to share your research and accelerate the path of innovation?
