I'm assuming that "decision tree" refers to something like graph reasoning. When I studied Bayesian graph reasoning & Hidden Markov, it seemed clear, logical, and a pure form of what we do for reasoning. And then you get to the sticky problem of actually training a network that implements a lot of interesting logic, reasoning, knowledge, etc. My understanding of the situation was that training those networks for any interesting or reasonably complex problem was still a mostly unsolved problem. I view ML as generally solving the same problems that those methods solve (but also more), but as having a completely practical and pragmatic training mechanism for some problems and promising avenues for most other problems. ML is about equal to graph reasoning, but with far better training techniques. I think it is possible to prove that in some sense. Stephen On 7/26/19 9:24 AM, Pascal Hitzler wrote: > Yes.
