- Abstract
- The basic idea of the paper is that every Bayesian network (BN)
model is uniquely described by a certain integral vector, named a
standard imset. Every score equivalent decomposable
criterion Q for learning BN models appears to be an
affine function of the standard imset. The algebraic view can
naturally be extended to databases: if a criterion Q of
the above mentioned kind is fixed then every database can be
represented in the form of a data vector (relative to
Q), which is a vector of the same dimension as the
standard imset.
