An efficient implementation of Determinantal Point Processes (DPP) in Julia.

Current features

  • Exact sampling [1] from DPP and k-DPP (can be executed in parallel).
  • MCMC sampling [2] from DPP and k-DPP (parallelization will be added).
  • pmf and logpmf evaluation functions [1] for DPP and k-DPP.

Planned features

  • Exact sampling using dual representation [1].
  • Better integration with MCMC frameworks in Julia (such as Lora.jl).
  • Fitting DPP and k-DPP models to data [3, 4].
  • Reduced rank DPP and k-DPP.
  • Kronecker Determinantal Point Processes [5].
