- back-propagation — (Or "backpropagation") A learning algorithm for modifying a feed-forward neural network which minimises a continuous "error function" or "objective function." Back-propagation is a "gradient descent" method of training in that it uses gradient information to modify the network weights to decrease the value of the error function on subsequent tests of the inputs. Other gradient-based methods from numerical analysis can be used to train networks more efficiently. Back-propagation makes use of a mathematical trick when the network is simulated on a digital computer, yielding in just two traversals of the network (once forward, and once back) both the difference between the desired and actual output, and the derivatives of this difference with respect to the connection weights.

- beta abstraction — [lambda-calculus] The conversion of an expression to an application of a lambda abstraction to an argument expression. Some subterm of the original expression becomes the argument of the abstraction and the rest becomes its body. E.g. 4+1 --> (\ x . x+1) 4 The opposite of beta abstraction is beta reduction. These are the two kinds of beta conversion.
- bidirectionality — capable of reacting or functioning in two, usually opposite, directions.

- block-structured — (language) Any programming language in which sections of source code contained within pairs of matching delimiters such as "" and "" (e.g. in C) or "begin" and "end" (e.g. Algol) are executed as a single unit. A block of code may be the body of a subroutine or function, or it may be controlled by conditional execution (if statement) or repeated execution (while statement, for statement, etc.). In all but the most primitive block structured languages a variable's scope can be limited to the block in which it is declared. Block-structured languages support structured programming where each block can be written without detailed knowledge of the inner workings of other blocks, thus allowing a top-down design approach. See also abstract data type, module.
