Riding the Error Waves: Using ODEs to Minimize Error in Artifical Neural Networks

In addition to CS 322, I’m enrolled in another course entitled “Modeling Cognition and Perception” (CogSt 416, Prof. Michael Spivey) in which we create artificial neural networks in MATLAB and train them in a variety of ways and on a variety of data sets. We predominantly study feed-forward neural networks, in which data progresses from […]

Mathematics You’ll <3: SVD and Collaborative Filtering

In our latest project in class, we’re using singular value decomposition to infer a light source from a given light-blocking shape and the resulting shadow it casts on a paper surface. As soon as I read the project description, I was excited about working on this project – it’s almost like being a spy, using […]

Graphical Ray-Tracing: Inception, Inspection, Improvement

My favorite topic of study so far in this course has been ray-tracing. I’m really interested in graphics and so I decided to dig up some more information about the origins of ray-tracing, its development, and its applications.
Ray-tracing was “invented” in 1968 by Arthur Appel, and since then other researchers have adopted and extended its […]
