数据挖掘中的bayes算法,很好的代码

/*----------------------------------------------------------------------
  domains
----------------------------------------------------------------------*/
dom(X) = ZZ;
dom(Y) = ZZ;
dom(C) = { a, b };

/*----------------------------------------------------------------------
  full Bayes classifier
----------------------------------------------------------------------*/
fbc(C) = {
  prob(C) = {
    a: 10,
    b: 10 };
  prob(X,Y|C) = {
    a: N([5.6, 3.7],
         [4.48889],
         [3.75556, 3.56667]),
    b: N([4.2, 6.4],
         [4.62222],
         [4.02222, 3.82222]) };
};

/*----------------------------------------------------------------------
  number of attributes: 3
  number of tuples    : 20
----------------------------------------------------------------------*/
