The powerset construction can be extended to transducers, or even weighted transducers, but sometimes fails to halt indeed, some non-deterministic transducers do not admit equivalent deterministic transducers. Given a transducer T, we want to build an equivalent transducer that has a unique initial state and such that no two transitions leaving any state share the same input label. In other words, the automaton computes a function that maps strings into the set is defined similarly. A computer is basically a state machine and each machine instruction is input that changes one or more states and may. In morphological parsing, an example would be inputting a string of letters into the FST, the FST would then output a string of morphemes.įinite State Transducers // Karlsruhe Institute of Technology, YouTube videoĪn automaton can be said to recognize a string if we view the content of its tape as input. state machine: In general, a state machine is any device that stores the status of something at a given time and can operate on input to change the status and/or cause an action or output to take place for any given change.
The next state of a cell depends only on the current stateof the cell and. An FST can be thought of as a translator or relater between strings in a set. Parallel Cellular Automata: A Model Program for Computational Science (1993). An FSA defines a formal language by defining a set of accepted strings, while an FST defines relations between sets of strings.Īn FST will read a set of strings on the input tape and generates a set of relations on the output tape. An FST is a type of finite-state automaton (FSA) that maps between two sets of symbols. Gambaran informal finite automata, studi kasus: uang elektronik 4. This contrasts with an ordinary finite-state automaton, which has a single tape. ( Learn how and when to remove this template message)Ī finite-state transducer ( FST) is a finite-state machine with two memory tapes, following the terminology for Turing machines: an input tape and an output tape.
