The Collective Knowledge project (or CK for short) is an open-source framework and repository to enable sustainable, collaborative and reproducible research and development.[1] CK is a small, portable, customizable and decentralized infrastructure which allows researchers:

  • share their code and data as reusable Python components with unified JSON API, JSON meta information, and distributed UID via GitHub and similar services (see the list of shared CK workflows, packages, software detection plugins and other components)
  • quickly prototype sustainable experimental workflows from shared components as LEGO(R) (such as multi-objective autotuning[2])
  • automate, crowdsource and reproduce experiments (see live repository)
  • unify predictive analytics (scikit-learn, R, DNN)
  • enable interactive articles and graphs (see online example)

Notable usages[edit]

Portable package manager[edit]

CK has an integrated cross-platform package manager with Python scripts, JSON API and JSON meta-description to automatically rebuild software environment on a user machine required to run a given shared research workflow (see documentation for more details). See already shared CK packages and software detection plugins.

Extensible AI API[edit]

CK provides a unified and extensible JSON API for multiple DNN frameworks including Caffe and TensorFlow while optimizing them across diverse hardware (mobile devices, HPC servers) and models.[12]

Reproducibility of experiments[edit]

CK enables reproducibility of experimental results via community involvement similar to Wikipedia and physics. Whenever a new workflow with all components is shared via GitHub, anyone can try it on a different machine, with different environment and using slightly different choices (compilers, libraries, data sets). Whenever an unexpected or wrong behavior is encountered, the community explains it, fixes components and shares them back as described in.[2]
