This PR has

  • creation of joint densities using operator*. It replaces the very poorly tested and confusing Compose, which was not used anywhere.
  • extensive testing
  • removed toFactor, which is a remnant from when we did not inherit from factors
  • exposes creation of a DiscretePrior from a vector of floats.
  • added a constructor from an ADT
  • some smaller documentation improvements

python/gtsam/tests/test_DiscreteConditional.py Outdated
pAB = prior * conditional
self.gtsamAssertEquals(prior, pAB.marginal(B[0]))

pA = DiscreteConditional(A % "5/4")

What is happening over here? We have (0, 2) % "5/4", not sure if this should be (0, 2), "5/4".

I am making fixes since other stuff is also breaking. 🙂

Thanks! Now I'm behind a CI traffic jam, though, so I'd prefer if you just comment in future? :-)

It'll be fast enough. Go enjoy a hot cup of coffee in this weather and it will be done before you know it. :)
