A priori (law) - adj. based on deduction or hypothesis, rather than on hard facts or knowledge
A priori (philosophy) - a priori is used in philosophy to refer to a type of knowledge that is independent of experience or non-empirical.
A priori (languages) - a priori constructed languages are those which try to categorize their vocabulary, either to express an underlying philosophical system, or to make it easier to memorize the completely new vocabulary.
A priori (engineering) - in engineering, synthetic a priori knowledge is the main objective of the process of analogical modelling in systems engineering.
A priori (statistics) - in statistics, a priori knowledge refers to a knowledge of the actual population, rather than that estimated by observation.
A priori (math modeling) - in mathematical modeling and data mining, one might try to spot classes and clusters of data. For example, if a credit card company examines its data, it could search for patterns representing fraudulent use; with a priori knowledge of which data represent fraud it can classify different behaviour into known categories of fraud and non-fraud, but without this knowledge, it can only identify different clusters or typical patterns of data. Use of a priori knowledge is typical in supervised learning, whereas detecting clusters in data without a priori knowledge is an example of unsupervised learning.
A priori (mathematics) - in mathematical literature, one often says proposition A "does not a priori imply" proposition B if any such implication would require some nontrivial reasoning. In particular, the question of whether proposition A implies proposition B a priori is independent of whether proposition A implies proposition B in fact.
