DIANA/HEP Fellowship for Matthew Feickert (Project Name is work in progress: DFGMark?)

There are examples of how to use the tool in the form of Jupyter notebooks in the Notebooks directory.

Project Timeline

• May 8th through May 21st

  • Create a GitHub repository for the project.
  • Design a template for binned models that is parametrized in terms of number of events, number of bins, number of channels, number of signal/background components, and number of parameters of interest and nuisance parameters.
    • See histfactorybench.py module
  • Begin documentation of the template model on the GitHub repository.
    • See Notebooks directory

• May 22nd through June 4th

  • Establish a precise mathematical formulation that is implementation-independent based on the HistFactory schema.
  • Begin study of data flow graph frameworks or of probabilistic programming frameworks.
    • Studying TensorFlow and Edward
  • Implement the template for the benchmark models with a HistFactory script.

• June 5th through June 18th

  • Conclude from study of data flow graph frameworks or of probabilistic programming frameworks which framework to pursue.
    • Using Edward
  • Begin implementation of the benchmark models in the selected framework.
  • Begin to write technical report.

• June 19th through July 2nd

  • Finish implementation of the benchmark models in the selected framework.
  • Apply benchmarks evaluating framework data and model parallelism.

• July 3rd through July 16th

  • Finish technical report.
  • Create tutorial on data flow graphs targeted for physicists.

• July 17th through August 8th

  • Upstream software contributions to address the identified limitations (if any).
  • Development of/Contribution to a probabilistic framework (if time permits).
