It is, however, often difficult to deduce which part of the data is noise (cf.model selection, test set, minimum description length, Bayesian inference, etc.).His popular fame as a great logician rests chiefly on the maxim attributed to him and known as Occam's razor. Nevertheless, the precise words sometimes attributed to William of Ockham, entia non sunt multiplicanda praeter necessitatem (entities must not be multiplied beyond necessity), William of Ockham's contribution seems to restrict the operation of this principle in matters pertaining to miracles and God's power; so, in the Eucharist, a plurality of miracles is possible, simply because it pleases God. 12, William of Ockham cites the principle of economy, Frustra fit per plura quod potest fieri per pauciora (It is futile to do with more things that which can be done with fewer"). Therefore, to the same natural effects we must, as far as possible, assign the same causes." Around 1960, Ray Solomonoff founded the theory of universal inductive inference, the theory of prediction based on observations; for example, predicting the next symbol based upon a given series of symbols.The term razor refers to distinguishing between two hypotheses either by "shaving away" unnecessary assumptions or cutting apart two similar conclusions. The only assumption is that the environment follows some unknown but computable probability distribution.In the scientific method, Occam's razor is not considered an irrefutable principle of logic or a scientific result; the preference for simplicity in the scientific method is based on the falsifiability criterion.For each accepted explanation of a phenomenon, there may be an extremely large, perhaps even incomprehensible, number of possible and more complex alternatives.
Even other empirical criteria, such as consilience, can never truly eliminate such explanations as competition.His principle states that among competing hypotheses, the one with the fewest assumptions should be selected or when you have two competing theories that make exactly the same predictions, the simpler one is the better.
