• Organization

  • There are three directories, each correspond to a subsection in the experiments section of the paper: simulation (simulation experiment), movielens (MovieLens data), us_natality (US Natality data).
  • Each directory has four sub directories: code, data, qsub, and result.
  • Directory 'code' has files of all the code (R source code) that was used in the analysis.
  • Directory 'data' has (if any) simulated data or real data that were used in the analysis.
  • Directory 'qsub' has SGE files (.q) that were used to submit jobs on a SGE cluster.
  • Directory 'result' has a sub directory 'img' and stores the result (if any) produced in the analysis. This directory may be empty or absent.

• Files

  • 'simulate_data.R' contains the code to simulate and partition the data.
  • 'partition_data.R' contains the code to partition the simulated or real data.
  • 'analyze_result.R' contains the code for analyzing the results of DPMC, WASP, and competing methods and making plots/tables.
  • 'dls_sampler.R' contains the code for the MCMC/Gibbs sampler of a subset posterior distribution. This is a modified version of the code in 'mcmc_sampler.R' using stochastic approximation.
  • 'dls_comb.R' contains the code for combining the subset posterior distribution.
  • accuracy.R' contains the code for measuring approximation errors.
  • 'submit.R' contains the code for the R code for submitting a job on the cluster. The files in 'qsub' directory use this file for running simulations. If you want to replicate our results, then you should see this file.
