Kyran Adams (Work Log)
Spring 2018
Kyran Adams Work Logs (log page)
2018-01-24: Kept working through the codebase and editing the matlab page. Deleted "strip_" files because they only work with task="monte_data". Deleted JCtest files because they were unnecessary. Deleted gurobi_gmm... because it was unused.
2018-01-22: Kept working on the Matlab page. Read reference paper in Estimating Unobserved Complementarities between Entrepreneurs and Venture Capitalists. Talked with Ed about what I'm supposed to do; I'm going to refactor the code and hopefully simplify it a bit and remove some redundancies, and figure out what each file does, what the data files mean, what the program outputs, and the general control flow.
Possibly useful info:
- only 'ga' and 'msm' work apparently, I have to verify this
- Christy and Abhijit both worked on this
- This program is supposed to solve for the distribution "unobserved complementarities" between VC and firms?
2018-01-19: Wrote page Using R in PostgreSQL. Also started wiki page Estimating Unobserved Complementarities between Entrepreneurs and Venture Capitalists Matlab Code. Tried to understand even a little of what's going on in this codebase
2018-01-18: Started work on running R functions from PostgreSQL queries following this tutorial. First installed R 3.4.3, then realized we needed R 3.3.0 for PL/R to work with PostgreSQL 9.5. Installed R 3.3.0. Link from tutorial for PL/R doesn't work, I used this instead. To use R from pgAdmin III, follow the instructions in the tutorial: choose the database, click SQL, and run "CREATE EXTENSION plr;". This was run on databases tigertest and template1. You should be able to run the given examples. Another possibly useful presentation on PL/R. Keep in mind, if the version of PostgreSQL is updated, both the R version and PL/R version will have to match it.
Fall 2017
2017-11-22: Fixed outjoiner.py python 3 compatibility bugs, color coded plot so errors are easier to see
2017-11-20: Continued debugging circles.py and changed outjoiner.py so it generates an error file, which contains all files with errors.
2017-11-17: Finished duplicated points code, but it still gives errors... Wrote a plotter so that I can debug it more.
2017-11-15: Worked on making duplicated points work with circles.py.
2017-11-13: Put some examples of nonworking files into OliverLovesCircles/problemdata. The files are not just St. Louis, but a lot of different files, meaning the bug is pretty widespread. Found possible solution; removing duplicate points before running program fixes it?
2017-11-10:
- Wrote some docs for ecircalg.py. Narrowed the St. Louis problem to the algorithm itself; it's returning circles with a radius of 0.0 for some reason. Wrote some testing code that prints errors if there are unenclosed points or circles with too few points.
- Also created a new parts list for the GPU build using server parts. Did some research on NVLink.
2017-11-08: Commented and wrote documentation for vc_circles, circles, and outjoiner.
2017-11-03: Fixed bug in circles.py that output place names in files as lists instead of strings (['S','t','L','o','u','i','s'] instead of "St. Louis"). Changed vc_circles.py to call outjoiner.py automatically. Refactored vc_circles.py, circles.py, and outjoiner.py to put all of the configuration in vc_circles.py. Wrote out method to plot circles using ArcMap in here.
2017-11-01: Familiarized with Enclosing Circle Algorithm to find St. Louis bug
2017-10-30: Rechecked parts compatibility, switched PSU and case
2017-10-27: Decided on dual GPU system, switched motherboard and CPU
2017-10-25: Worked on the partpicker for the dual GPU build.
2017-10-23: Started researching GPU Build. Researched the practical differences between single vs. multiple GPUs.
2017-10-20: Set up my wiki page :)
