      Three road blocks to solve for artifical general intelligence (#AGI) 1) Massive Multitask learning with a single joint model 2) Ability of algorithms to update their objective functions in continuous learning 3) Learnable combination of fuzzy/fluid and symbolic reasoning

      I think you have missed an even much greater challenge: common sense reasoning and abductive reasoning.

      In probabilistic reasoning, deduction, induction, and abduction all are implemented by the same reasoning engine. @Grady_Booch, do you see a difference among them?

      Absolutely. Abductive reasoning is about building models and theories of the world, of others, and of the self. Those are all generative things, not things to be measured by probabilistic methods.

      We AI folks often define probability distributions over structures (e.g., grammars). Abduction is then MAP (maximum a posteriori) inference.

      Right...but from what are you inferring? How does such an approach generate a model or theory?

      From data (either observational or the result of experiments).

      @tdietterich i don’t understand your answer to @Grady_Booch. a set of data by itself is not a theory.

          My main concern is treating "abduction" as some special kind of inference. Probabilistic reasoning unifies deduction, induction, and abduction in a single, elegant framework. The difference isn't the kind of reasoning but the type of objects over which we are reasoning.

          Maybe, but how then to make all that work in, say, making the kinds of inferences that Sherlock Holmes made or in devising a machine that could induce a double helix from the data Watson and Crick had available. @yudapearl is right that causality is a key part of the mix.
