In addition to too many blogs, here are a few papers, writeups, and other assorted writings I have done. If you’re interested in looking at or using the code or data for any of the papers below, you can check my GitHub or contact me directly about accessing that.
PDF – Ali, K., Leung, K., Konik, T., Choi, D., Shapiro, D. (2010). Knowledge-Directed Theory Revision. Inductive Logic Programming 2009, Lecture Notes in Computer Science, 5989, 1–8.
A paper on a theory revision module for the ICARUS cognitive architecture, based on work from a summer internship.
PDF – Identifying Actors in Political Activism over Twitter
This paper was written for CS378, “Phenomenological Foundation of Cognition, Language & Computation.” I was interested in the use of Twitter for political activism (such as the Egyptian protests) and thought that there were interesting questions about identity and commitment in that context. I take some ideas from network models to understand the roles that individuals have in terms of concrete actions, and I connect that to some empirical work on types of actors in activism on Twitter to understand where identity comes from.
PDF – Evolution of Internet Information Consumption Through Bookmarking
This paper was written for CS224W, “Social and Information Network Analysis.” The question I had going into this was whether we could quantify how information overload might be reflected in changes in internet usage. Particularly, Neal Gabler here complains that we can’t grapple with big ideas and are stuck in the constant flow of unimportant data. I tackled this hypothesis by looking at Delicious data and seeing whether the distribution over bookmarks has changed from year to year. If he’s right, we should see more bookmarks happen sooner and less of a long tail. The basic result is that over 3 years, things look pretty much exactly the same, and I also try to come up with a model to explain the data.
PDF – A Connectionist Model for Visual Search via Evidence Accumulation
Final writeup for the 2nd version of the model in the paper below. Again, there are some pretty serious problems, but it does kind of work, too.
PDF – A Connectionist Model for Visual Search via Excitation
A final writeup on a project for Jay’s PDP class where I tried a very simple model for visual search. The model largely doesn’t work, but it was great for me to find out all of the things I don’t know about visual search and need to research more in-depth.
PDF – Robinson, D., Leung, K., Falco, X. Spoken Language Identification With Hierarchical Temporal Memories.
A final writeup on a project for a machine learning class where we tried using Numenta’s HTM technology to improve classification of different spoken languages.
PDF – Does Word Order Affect Processing?
Minor research paper for a psycholinguistics class where I analyze the importance of Behaghel’s Law on processing. (Hint: it’s not very important)
PDF – A Review of Predictions from the Dynamic Routing Circuit
A final writeup for a class on models of the neocortex. In it, I review some stuff from an earlier Olshausen model. It’s a literature review of neuroscience papers, so pretty far out of my comfort zone, but it was fun.
PDF – Direct and Indirect Consequences of Chosen and Alternative Actions
Final paper where I extend Propositional Dynamic Logic to include some ideas of consequence. The paper leans heavily on material from class that I don’t really explain, and I’m not sure how original the ideas are.
PDF – You Use This Washroom Often?
Fun essay I wrote for a creative nonfiction class where I wander around washrooms on campus.
