We all know how traffic lights work. If we would assign numbers to the activation sequence it would look like this: 1, 2, 3, 1, 2, 3, 1, 2, ... where 1 = Green, 2 = Orange and 3 = Red
According to CLA, predictions are purely mathematical and derive from simple probability algorithms. Which means that the temporal connections between cells don't count for predictions. In the traffic lights example when Orange lights up (2) given a sequence of: 1, 2, 3, 1, 2, 3, 1, 2 ... the prediction union is: 1 - Green - 3 / 8= 37,5% 2 - Orange - 3 / 8 = 37,5% 3 - Red - 2 / 8 = 25% So, after Orange the most likely to light up next is either Green or Orange again which will result in the entire human species gone extinct by car accidents. Why are we still alive? Is it because in reality traffic lights are being perceived differently (after all they are not simple sequences but tools of man that we learned how they work) or is it simply because I have misinterpreted how CLA makes predictions? Can we understand traffic lights without being told that it's a repeating sequence of 1, 2, 3, ... ?
