Well, I made up my appointment from yesterday today. However this involves hours of sitting still, and my laptop was not an old computer, and the situation was such that I didn't have a free arm to write with. On the other hand I had a good conversation about climate. This person pointed out that her parents had in effect been environmentalists in that plastic bags had not come into widespread use, neither cars really. They had the same sentiment that environmentalism is doomed because other countries will put middle class short term greed over anything else. So while it is a nice thought to preserve the environment, the world is doomed anyway. Another person I spoke to had had a similar view. While wiling away the hours penless, I had the thought to put my bunzy hash-tables together with my prover planner plans. A recap: I drafted a package, bunzy hop (binry-hop, bunny-hop) in which the :test was a hopfield net lookup of the key (against other keys). This data structure really is nuts. And by nuts I mean deep and non-linear. Yesterday I was pondering - given how robot labor is almost the same as human labor anyway, except less dynamic and faster, but not by a lot, what would a robot planner want to be like, left to their own devices? Planning problems are the same complexity for a robot as for a human. Since I am using an automatic prover as a planner / model, this case is relevant: Since the advent of automatic provers, first order proofs started emerging- things that are mathematically true, but that are so large they are not hand-verifiable by humans. Such as the four-color-theorem. (Later work produced a smaller four-color-theorem proof, which would in principle only take two solid months of expert human effort to manually verify, assuming no mistakes, though nobody has done it). So how can I get my theorem planner to produce plans that are deliberately out of human scope but within comfortable robot scope? Classical hopfield nets have cryptographic properties. Basically impossible-for-human plans can be created by using Hopfield nets if only the robot ever knows about the Hopfield net per se. Kind of cheating, but the technology is having proofs that are verifiable, but not ~ decryptable by humans. My simple case is like this: (1) *classical* binry-hop hash. The bit-arrays are the keys, :test is Hopfield net convergence (then 'equal). The values of the hash-table are lambdas; an action to make in the context of the key being sensed. (2) The robot takes a picture of its surroundings. Could be a feature vector, could be a binarized image or a sound, it doesn't matter. After converging, the original picture is added (in the classical hopfield net sense) to the matrix calculation, and the image is discarded (= lost). The image is still inside the hopfield net, and in principle could be matched, and affects its behaviour, and, I think, can be used in theorems involving lookups from this hash, but the system is also cryptographically opaque. Aside: My sketch of how to encrypt a pictrogram (or anything) into a classical hopfield net: Have the pictogram. As long as it fits in the net, it's fine. Have a bernoulli sequence the same size. logand the pictogram and bernoulli sequences. Add this destination to the classical hopfield net. Now a naieve but accurate sketch of the pictogram will be a 50% (ish) match with that pictogram, presumably closer to it than anything else, hence it should converge there. The pictogram could be attached to a secret message. The hopfield net is then stuffed to capacity with random garbage, or other pictogram secret messages. Anyway, simply using this cryptographic classical hopfield net approach in the development of a plan (or other theorem) is a shortcut to being robots- only. In order to not be reliant on the cryptography to gain opacity, the snapshot-taking could also be something unattainable by humans (pretty much anything with a high data density but low enough for robot handling). (Olde robot handling). If we have our bunny robot advance forward in time, making and executing plans that modify itself, in a manner opaque to humans (by data) and other robots (the cryptographic complexity beats both humans and robots). We could also do the same sans cryptography with a super-high capacity dense hopfield net (which do not have the cryptographic property, at least in simple update formulation). My intuition is that this idea is crazy beyond normal crazy. I do owe 40-50 years of literature review on surrounding topics though... Which I guess I could be doing on printed paper.
