For example, gravity is a constraint, but everything that is observed as an effect of gravity is a _pattern_. %% “To arrive at predictions, brains require something on which these predictions can be based—predictive systems require _constraints_ on the set of prior probabilities and likelihoods that should be taken into account as they finalize and settle upon a set of predictions for any given sensory-neural situation (Friston, 2003; Kemp et al., 2007; Tenenbaum et al., 2011; Blokpoel et al., 2012; Clark, 2013; Hohwy, 2013). Without such constraints, it is impossible for any intelligent system to narrow down the possibilities enough to settle on a single hypothesis or set of hypotheses (Russell and Norvig, 2010; Tenenbaum et al., 2011; Blokpoel et al., 2012).” {which in PP are known as _priors_}.
