Abstraction in the physical world Yaakov (J) Stein CTO, RAD There are 2 techniques frequently used to solve hard problems and which have been raised to an art in computer science Way of classifying information from abstract (general) to concrete (specific) . . Level 4:. Abstractions. Level 3: . Noun Classes, broad group names with little specification. Level 2:. Noun Categories, more definite groups. Tien-Duy. B. Le, . Shaowei. Wang, and David Lo.
