Re: Whatever happened to the term "expert system"?
GIGO - whoever has control of the datasets has control of the output, and there isn't a single data set that isn't biased by some rule(s) that has to be decided upon arbitrarily. Someone will round to whole numbers, for example, while someone else might round to 10ths, and someone else to 100ths - something that simple when run through any algorithm will create more and more distortion over time. Then there is the guy that, in setting up a simple data set (what data needs to be imputed to make sure an airplane will make it from point a to point b) assumes that the 20000 represents gallons, rather than pounds, of fuel), and the plane lands 2000 miles short of the runway.........
