regression

Few of these groups or communities that are classed as "savage" show no traces of regression from a more advanced cultural stage.

I have done past life regressions on my own through self-hypnosis techniques that I learned in Brian Weiss's book Many Lives, Many Masters as well as with past life regression tapes.

Supervised learning problems are categorized into "regression" and "classification" problems. In a regression problem, we are trying to predict results within a continuous output, meaning that we are trying to map input variables to some continuous function.
