OR:

Feedforward is the provision of context of what one wants to communicate prior to that communication. In purposeful activity, feedforward creates an expectation which the actor anticipates. When expected experience occurs, this provides confirmatory feedback.

Richards subsequently continued: "The point is that feedforward is a needed prescription or plan for a feedback, to which the actual feedback may or may not confirm." The term was picked up and developed by the cybernetics community. This enabled the word to then be introduced to more specific fields such as

Different applications of feedforward


Control

Feed forward is a type of element or pathway within a control system. Feedforward control uses measurement of a ''disturbance input'' to control a ''manipulated input''. This differs from feedback, which uses measurement of any output to control a manipulated input.


Management

Feedforward has been applied to the context of management. It often involves giving a pre-feedback to a person or an organization from which you are expecting a feedback.


Neural network

Behavioral and cognitive science

Feedforward is the concept of learning from the future concerning the desired behavior which the subject is encouraged to adopt.
