Image via CrunchBase It looks like some of the top players in the Netflix Prize competition have teamed up and finally broke the 10% improvement barrier. I know I’m a few days late on this, though not because I didn’t see when it happened. I’ve been battling an ear infection all week and it has [...]

Stacked Agents Model

This is research I did a while ago and presented Monday to fulfill the requirements of my Masters degree. The presentation only needed to be about 20 minutes, so it was a very short intro. We have moved on since then, so when I say future work, I really mean future work. The post is [...]
MS in Language Technologies

I just completed the final requirements of my Masters degree today (the details of which I will save for a future post). It has been a difficult road, and I’m glad it’s done. I didn’t attend any sort of graduation ceremonies, because I don’t go for that sort of thing — at all. Until today, [...]

It is very important to know your audience when marketing your product. This was posted at the bus stop just outside the CS department at CMU.

Today is the official opening day of GWAP: Games with a Purpose. This is one of two research projects I have been working on for the past few months, though my involvement with GWAP so far has only been in the form of attending meetings, minor testing, and offering my sage gaming advice (and by [...]
Sampling of Game Demos

I attended some of the final presentations of an undergrad class on Game Programming today with a friend. We went in expecting something more like a poster session, where people are arrayed around a room showing their work off to a few people who managed to crowd around them. The poster session is ideal for [...]

I’ve been messing around with recommender systems for the past year and a half, but not using the kNN (k-Nearest Neighbors) algorithm. However, my current homework assignment for my Information Retrieval class is to implement kNN for a subset of the Netflix Prize data. The data we are working with is about 800k ratings, which [...]
Who created OpenEphyra?

OpenEphyra is a question answering (QA) system developed here at the Language Technologies Institute by Nico Schlaefer. He began his work at the University of Karlsruhe in Germany, but has since continued it at CMU and is currently a PhD student here. Since it is a home-grown language technologies package, I decided to check it [...]
Spam of the Day 2008-02-07

I go through my spam everyday to make sure that false positives don’t get deleted. For whatever reason, stuff coming from the Help Desk at CMU gets labeled as spam a lot. I’m not saying it sounds like word salad (*cough*), but it trips off gmail’s spam sensors. The good thing about gmail is a [...]

Ed Clarke, a professor of Computer Science at CMU, just won the 2007 ACM Turing Award. The ACM is the Association for Computing Machinery and is the oldest professional group for the computing industry. I first became a member in 2005 and have maintained that membership since. The Turing Award is given in honor of [...]
