LearningNets

A small example used in the tutorial to illustrate EM learning.

The complete example (including all of the simulated data sets) can be found at http://pluto.coe.fsu.edu/BNinEA/Examples/LearningNets/ (tarball, zip).

Basic model

The basic model has 2 latent variable and three observable variables.

Data sets

Note that most of the simulated data sets consist of just the observable values, although as the data are simulated, it is possible to get values for the latent proficiency variables as well.

The data are in Netica? case file format, which is basically tab separated data. The compressed version are compresses with gzip (see Tools).
