Make weight distribution of Sum node an SPN and expose the random choice #3

Closed fsaad closed 4 years ago

fsaad commented 4 years ago

The SPN should have one symbolic variable
The SPN leaf nodes should be of Nominal type.

fsaad commented 4 years ago

This feature can be easily implemented by making the child nodes of the sum be products of a nominal SPN that is atomic at the index of each component.

fsaad commented 4 years ago

Only part of this issue was closed, i.e. the weight is still not a SPN. Unified by #10
