Topic discovery and diversity

General description

  • docs:
  • feedbacks contains all the comments and feedbacks received from multiple people (listed in the report's acknowledgement section)
  • src:
    • topic_discovery.R: definitions for TopicDiscovery class (initialization and simulation)
    • topic_analysis.R: functions for running diversity analysis and time analysis
  • scripts:
    • rmd2rscript.R: convert Rmd files in this folder to R scripts to run non-interactively
    • sim-block.R[md]: simulation with block/group models (i.e. using sample_sbm)
    • sim-nonblock.R[md]: simulation with nonblock models (i.e. using sample_[pa,gnp,smallworld])
    • analyze-diversity-through-time.R[md]: topic diversity time analysis scripts
    • vis-demo.Rmd: generate some demo plots about model parameters
    • vis-analysis.Rmd: analysis plots for all simulations
  • svproc/cnasubm: latex files to generate CNA21 submission, along with necessary figure and bib files. The final document is also in docs/Pham-CNA2021.pdf.
  • data: the data and analyses generated from scripts can be downloaded at https://doi.org/10.6084/m9.figshare.17086832.v1

Notes

  • To run simulation/visualization scripts in the scripts folder (scripts/sim-* files), move to main folder first, this is because they were written to be run from main folder, so the data file paths in the params_df are saved as data/XXX/data-001234.rds instead of ../data/XXX/data-001234.rds. Then they were moved to the scripts folder for organization purposes. This does need improvement in the future.

  • For update functions:

    • update_bipartite_topicagent and update_learnt_topic are quite manual and slow but rid off duplicates and already learnt subjects
    • update_via_matmul is much faster but the beta route doesn't choose a friend of aoi before hand
