| Some questions: We act like stimuli are exact things but the brain is all about abstraction. In fact, a certain amount of entropy/information enters your beain every day from vision, smell, touch, etc. Its not stored in full fidelity. There arent enough nuerons or energy for that. So what is lost? Well...whatever isnt abstractable, right? You celebrate your birthday. You remember blowing out the cake in pristine vision. But how much of that 'movie reel' inside your head is actually a superposition of abstracted reality vs actual observed reality? All Im asking is, is it even worth it to think of a human being in terms of absolute information when their memories are so sparse from reality. We remember whats important. And the things that are important, weve remembered to remember. But ultimately, the actual holding power of the brain is quite small. The brain is a master of deep abstraction from sparsity. Is it like a quantum system? Where the superposition values of one subcortical system are flattened by another? So that a whole brain belief/memory is a function of the fuzzyness of each subsystem being exacted/wave function flattened by the heuristic correlation/connection between all the shitty data? I think we need to start thinking about sparsity. The universe is sparse when it comes to using 3d space. Holographic principle says physics is so symmetrical that we sparsely use 3d space. Such that our entire universe could take place on 2d space. Max Tegmark gave a talk about how deep learning works so well because of the sparsity of faces or music or voices, the overwhelming symmetry/redundance in physics and nature. And transitively, humans. |
What gets processed and enters consciousness only a small percentage of the actual raw input from sensory "devices".
What get's stored is even less than that, is highly inaccurate and degrades quickly.
Abstraction comes in at finding patterns in the lossy data, and filling in the gaps in the data to form a coherent perception/memory.
