      I'm inclined to agree that a focus on 'common sense and deep understanding' is the right approach. But I suspect it can be done with deep learning and the right architecture

      of course, a lot rests on what you mean by right architecture, and whether you include symbol-manipulation (which we argue is a key component) in that scope. you and i probably ultimately agree on the value of *hybrid* architecture.

      I think we can agree that the brain has specialized components that work in concert to achieve human cognition. We can furthermore agree that each of these components is built of specialized neural networks. Hybrid architectures are a stepping stone towards more general kinds.

      if you have specialized components that operate under different principles, you have hybrid systems.

      Can you more formally define what these hybrid systems you have in mind are? I sense there's a lot of overlap between what DL researchers consider as architecture choices or other inductive biases.

      Replying to @santoroAI @GaryMarcus and

      In lieu of @GaryMarcus definition, I would define a hybrid system as that having components that are both grown (i.e. trained like a neural network) and human-engineered (i.e. tree search). I argue that the latter can also be grown and thus it is a stepping stone.

      not what i meant, though i agree that most effective cognitive systems will blend learned and hand-wired components. i used # term hybrid re eg systems that combine symbol-manipulation (please see chapter 2 of Algebraic Mind) with deep learning. Alpha* is a hybrid in both senses

      Replying to @GaryMarcus @IntuitMachine and

      I think some frustration re: these hybrid proposals stems from the interpretation of what a "symbol" is, and what a "symbolic system" is, since it seems here to be only loosely based on its historically intended definition. i.e., people are coming in with different assumptions

      over and over you guys want to debate with me but don’t seem willing to do me the courtesy of reading two chapters where i actually lay out the arguments carefully. that has the consequence of lowering the level of discussion. nobody benefits.

      I challenge you all to make your respective “tables” classifying the current literature (see other tweet), to make any definitions you may have map onto the concrete. (This could be like a research-level supplement to Gary’s book (which I will buy).)
