Does Active Learning Work?

Here's work from yesterday. Unfortunately, I encountered several walls during my look at NASA93 before I begin working on all of the other datasets.

The first section of the document describes the variables and our ranking function for selecting devious children pairs.

The second section details everything I worked on yesterday and the pitfalls encountered.

Status of Compass Comparison Defect Prediction Experiments

I'm currently working my way through NASA and Softlab datasets shown in the table testing two Compass variations with different stopping rules to K-means with k = 1,2,4,8,16 and bisecting K-means with k = 4,6 and 8. I'm using leave-one-out and 66%/33% train-test slices repeated 20 times for cross-val.

The NASA datasets are still running, but ugly, non-formatted Softlab results are available in: http://www.unbox.org/wisp/var/kel/CompassDefectResults/

Flight of the MILL

Four brave researchers take time from their busy schedules to embark on a journey via helicopter that will bring them closer together than ever before. Their adventure can be now be shared thanks to the power of a Blackberry and YouTube.

A special thanks to Jacky Keung for the helicopter. Dr. Menzies will be lucky if he gets it back.
