Generally with the free energy principle you’re minimizing the level of surprise from an internal model and the environment. This can be effected by either altering the model or taking action in the environment. Could you frame your work in these terms?
@Thinkstr
@Thinkstr 12 сағат бұрын
Hi, thanks for watching! If I understand correctly, the paper in this video applies both those paths. The model is improved based on new observations to minimize surprise. The optional way to do that is by taking actions finding parts of the environment which are still surprising until they are understand. I think this is what is called Active Inference. Although, a criticism of the FEB is that taking the action of sitting in a dark room definitely limits surprise. But if someone knocks on the door, that's surprising and leads to uncertainty! So it helps to explore and meet the neighbors instead.

@@Thinkstr yes, I get that much, great explanation there. These actions though initially increase the level of surprise, which of course the algorithm then beats back with a stick. The end result is a model which efficiently explored the space in which to model things. I think when you said “essentially sitting in a dark room would eliminate surprise” is pretty dead on. So would we say an additional mechanism, that effects this exploration is at play, that it must exist, it is essential?

One common argument from creationists is that an intermediate species would not be optimally adapted to neither land nor sea. I think the main problem is that they lack perspective on the variety of niches and the magnitude of the timescales that evolution works on. Evolutionary biologists might understand these as an abstract concept, but still let the tradition of classifying into singular species and a limited set of environments pollute the discussion. I agree, this has more to do with semantics.

so ideally you have a data set of not just poor handwriting, but examples where 2s look like 1s and 1s look like 2s, so it gets good at solving the edge cases. you want there to be a fine line between concepts, and weird examples allows it to classify clearly. labeling ambiguous examples is worth more than labeling obvious examples, because they better define the boundary of the vector space holding these answers. extremely ambiguous examples are by definition, at the boundary of their classification, and if they cancel each other out, you don't really need normal examples, because those are just the average of the extreme examples. Weird examples don't just make it better at remembering, it makes it better at understanding the actual boundaries of the concepts its classifying.

Thanks for creating this video, this makes active inference and the free energy principle much clearer, and also explains how the brain thinks to minimize perception and reality. The examples were great, and I understood it correctly; that we prefer to assume we are full (not hungry) vs hungry, so our tendency is to eat to minimize the error (free energy) between thinking we are full and being full, also when we think we will accomplish something we put more effort to accomplish it so that we don't have an error (free energy) between thinking we accomplished it and not doing it. The active inference is the actions to minimize the free energy. I also think this is why once people make up their mind about something, even if they are wrong they are very difficult to change their mind to what is correct.
