The brain is just a bunch of ifs

• taneq 3y ago
  Quantity of ifs has a quality all of its own. After all, a CPU is just a bunch of transistors, and a transistor is just an 'if'.

    This was the ELI5 part. Of course that the wiring of the ifs is as importany as the quantity of ifs

      Aah, true, and therein lies the rub. I definitely think the structure and function of cortical columns as described by Numenta is getting close to the mark on a part of it. It seems to me like Transformer models are doing something very similar to this, where each attention head is roughly analogous to a cortical column. You can't build a mind on prediction alone, though (or can you?) so we need helper structures like the hippocampus.

        prediction is an essential part. basically between the state you have + the inputs from the sensors you generate a prediction. this prediction is compared to the "real world" and the state is adjusted until the prediction matches the output.
