#Coursework Code Samples I have uploaded a few things I have worked on this past year. Hopefully, they can serve as reference for other students. Suggestions for improvements are very welcome.
- relationship-model.nlogo, relationship-model-hubnet.nlogo: A NetLogo model that explores how relationships form. The user can adjust macro-level variables and observe how successful relationships, unhappy relationships and single individuals form. For more information, open the model in NetLogo and click on the Info tab. Accompanying HubNet model allows user to ask other players out on dates as well as accept/reject proposals from others. User cannot see his/her own attractiveness score, but is able to see everyone else's.
- one-direction-game.pl: A simple game written in Prolog where the player's goal is to date a member of One Direction. The player visits various locations to find members and to better his/her chances at getting 1/5 to agree to a date. However, the player has only a limited amount of resources and must reach the goal before time or money runs out!
- viterbi.py: An implementation of the Viterbi algorithm in Python.
- sudoku.py: Methods for a Sudoku solver, written in Python.
- naive-bayes.py: Uses the Naive Bayes algorithm and the Chi-Squared test to perform sentiment analysis on various movie reviews, written in Python.
- nfoldpolyfit.py: plots MSE vs. kth polynomial regressions (for k from 0 to 9) using n-fold cross-validation given X and Y values in a csv file and fits the best choice k on data, written in Python and can be run with:
python nfoldpolyfit.py csvfile maxk nfolds verbose- train-hopfield.py: trains hopfield network on binary image data from the Semeion handwriting digit data set and outputs weight vector, written in Python and can be run with:
python train-hopfield.py datafile- gmmest.py, gmmclassify.py - uses the EM algorithm to estimate parameters of Gaussian Mixture Model and then classifies points according to learned GMM, written in Python and can be run with
python gmmest.py datafile mu_init var_init wt_init iterations
python gmmclassify.py datafile mu1 var1 wt1 mu1 var1 wt1 prior1- basics.rkt: A few basic functions in Scheme/Racket.
- garbage-collector.rkt: An implementation of a two space copying collector in Scheme/Racket.
