    Note that there are at least three versions of the ALARM network floating
    around. They have the same structure, but different probabilities:

    1. Used in Cooper and Herskovits, Machine Learning, 1995.

    2. A later version used in Heckerman, Geiger, Chickering, Machine Learning,
    1997. This net is available at
    ftp.research.microsoft.com/pub/dtg/alarm/alarm.dsc.

    3. An even later version that is included with Herskovits' Bayes-net tool
    called Ergo.

    I'm not sure which one of these (if any) is on the repository.

    Hi -
    The ALARM network was originally developed by Beinlich et al. as an
    experimental prototype that helps interpret monitoring data to alert
    anesthesiologist to various situations in the operating room. It has
    about 37 nodes, some binary, some non-binary. The original paper about
    ALARM is the following:

    http://smi-web.stanford.edu/pubs/SMI_Abstracts/SMI-88-0239.html
    I. A. Beinlich, H. J. Suermondt, R. M. Chavez, & G. F. Cooper. The ALARM
    Monitoring System: A Case Study with Two Probablistic Inference
    Techniques for Belief Networks. Second European Conference on Artificial
    Intelligence in Medicine, London, 38:247-256. 1989.

    ALARM now ships as an example network with most common inference
    engines. You can download it from the Bayesian network repository at
    Berkeley -
    http://www-nt.cs.berkeley.edu/home/nir/public_html/Repository/

    ALARM was first used in belief-network learning by Herskovits and Cooper
    as a test of their learning methods, Kutato and K2. An early paper on
    that is:

    http://smi-web.stanford.edu/pubs/SMI_Abstracts/SMI-90-0305.html
    E. Herskovits & G. Cooper. Kutato: An Entropy-Driven System for
    Construction of Probabilistic Expert Systems from Databases. Sixth
    Conference on
    Uncertainty in Artificial Intelligence, Cambridge, MA, 54-62. 1990.

    Hope this helps
