I have written for a few other blogs, including:

I have also written a few papers and write-ups for college classes and research. 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 – Engineers for Designers

A presentation I have done for Whitespace a few times to teach product designers how to work with software engineers. You can read corresponding notes here.

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

Research paper 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

Project writeup for 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

Project 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

Project writeup for CS209A, Jay McClelland’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.

Project writeup for CS229, “Machine Learning”, 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 conduct an experiment to 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

Survey paper 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 for CS222, “Intelligent Interaction and Rational Agency” 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 for a creative nonfiction class. I wandered around washrooms on campus.

2 thoughts on “Writing”

  1. Just found your paper, “Identifying Actors in Political Activism over Twitter”. Very interesting, and your idea that “…participation is best understood as the origin of cascades in the network” is very useful.

    Thanks for posting the paper! Is the code available on github?


    1. Glad to see someone stumble across the paper, though I wish I had spent more time fleshing out my thoughts and developing a more clear argument.

      I actually didn’t write any code for it. Most of the data I took from the Lotan et al paper, and the model I’m working from is from the Hassenpour paper. The rest of it is mostly fluff around that. You should take a look at those papers if you’re interested in reading more.
