      I tend to agree, but I am also still afraid that someone accidentally misconfigures the loss function of GPT-2 and instead of 20 layers of style it discovers five layers of meaning, and comes after us. :)https://twitter.com/dmonett/status/1212992388546932736 …

      I guarantee that won't happen :) You can't discover meaning if you don't represent knowledge, let alone multimodal grounds of knowledge. Also, you can't manipulate knowledge without having a cognitively powerful filtering mechanism. Both points are the essence of my papers. :)

      I don't think so. The meaning of a datum is given by its relation to a unified, [more or less] coherent model of the universe. Knowledge is a second order model: a model of what you implemented in your simulations and simulacra of the universe, and thus what you know about it.

      Yes, I agree. That is why I said "multimodal grounds" refering to the symbol grounding problem. In my work, I use the computational neuroscience concept, "free energy principle", which is based on the idea of beliefs about the model of the environment the agent inhabits.

      By multimodal grounds, I mean multiple grounded references of knowledge that represent a deterministic model of the universe, upon which all stochastic models may successively take place. But what we are both talking about, is what all current DL models lack. I explain that […]

      from a math, stats & philosophy persp. in my next article. Current DL models, as GPT-2 don't have a model of the universe to base its knowledge. That is why you'd see me & Gary blame their lack of "priors". Their words are referenced to how many times it appeared in the corpus.

      The priors are the result of an evolutionary search. Nothing a DL algorithm cannot do.

      “Their words are referenced to how many times it appeared in the corpus“ ... in the context of cooccuring other words. And the same is true for the blips on your retina, skin or thalamus.

      Given Neuroscience's perspective, I don't think we recognize things by the repeating pattern in single pixel value combinations. Yes, there are low representation of knowledge, but not single values. Another note is the ability to reflect back on the brain for a more complex […]

      We don’t have any other access to reality but counting the noisy bits on our systemic interface. Evolving priors is part of counting. Higher order relationships between observed patters is still counting.

          Josha, again I don't disagree. I am not even against correlation. Just not frequency based correlations of non universal & non grounded knowledge. Speaking of noise, I agree. However, of one has no high abstraction of grounded knowledge, one would not even be aware of noise.

          What matters is not what opinion you hold, but what arguments support it. I don’t understand your prerequisite of “universal, grounded knowledge”. Are you sure your epistemology is sound?
