Transduction
From Wikipedia, the free encyclopedia
The word transduction has several meanings:
- In biophysics, transduction is the conveyance of energy from one electron (a donor) to another (a receptor), at the same time that the class of energy changes.
- In cell biology, signal transduction is any process by which a cell converts one kind of signal or stimulus into another.
- In developmental psychology, transduction is reasoning from specific cases to specific cases, typically employed by children.
- In mechanical and electrical engineering, transduction is a process that converts one type of energy to another. A device that does this is called a transducer.
- In cybernetics and systems engineering, notably in the Viable System Model, transduction is a process or mechanism that converts signals from one form to another.
- In genetics, transduction is the transfer of viral, bacterial, or both bacterial and viral DNA from one cell to another via bacteriophage.
- In machine learning, transduction is directly drawing conclusions about new data from previous data, without constructing a model.
- In physiology, transduction is transportation of stimuli to the nervous system.
- In semiotics, transduction is the translation from a sign or concept from one field of knowledge to a different one, involving a transformation that keeps an original conection in its phenomenological deepest level. It differs from "traduction" with regard to its necessity of adaptation.
