Detailed Description

CPDDiscreteInterface is an abstract base class that represents a conditional probability distribution $ Pr(x|y) $.

The interface (so far) only implements Get. In the future

  • we may want to add a function that allows multiplication of CPDDiscreteInterface's ?
  • I think it might not be convenient to add Set() functions (each implementation might use different set functions? E.g. a CPD based on rules may use quite a different mechanism to set probabilities than a CPT)
