The sparta package implements new methods
(multiplication, marginalization etc.) for dealing with conditional
probability tables (CPTs) and are especially useful when the CPTs are
sparse.

implements belief propagation via the Junction Tree Algorithm which
relies heavily on sparta tables. See also https://github.com/mlindsk/pednoa for a usecase of
jti where “ordinary/dense” table operations will fail.
