    Hello all,

    Is there any algorithms of Bayesian Network to work directly on the
    mixture of continuous and categorical variables?

    The classification problem that I am working on has 37 input variables, 15
    of them are categorical and the rest of them are continuous. To my
    understanding, I need to discretize the continuous varibles in order to
    apply some commonly used algorithms (such as junction tree) to construct
    and estimate BNs. Since a large portion of the input variables are
    continuous, I am afraid of loss of information by discretizing them.
    References and input on working directly on the mixture will
    be highly appreciated. I would also like to have any comments and
    experiences on how much gain we can get from working on the mixture
    directly over transforming all variables into discrete. Thanks.

    Best regards,

    Julie
