-The output-
Y = the output = the psyche, and it is merely the sum of each individual function added together. Again, it doesn't take a genius to figure out that the psyche is the sum of its parts.
I think an alternative interpretation is needed here, by the way. The resulting value signifies the extent to which the + functions overpower the - functions.

A potential weakness of the model: when the variables a,b,c,d and the values of the functions themselves amount to less than 1, the higher dimensionality functions end up weakening their accompanied function as opposed to strengthening it. So one needs to be clear about the fact that 1 is the lowest value the model can handle, unless one thinks it acceptable that in situations where experience is very low, the PoLR function has an advantage over the base function.
