forward analysis การใช้
- Walk forward analysis was originally discussed by Robert E . Pardo.
- That's not to say the work was poor; Brown's writing is strong and he puts forward analysis that sounds downright reasonable.
- Some works written by historians, such as Simone Piognant and Bernard Hours among the most recent, put forward analysis and developments more worthy of interest.
- Widening techniques and the closely related " acceleration " techniques are used in the " forward analysis " of systems in the discipline of symbolic model checking.
- ""'Walk Forward Analysis " "'does optimization on a training set; test on a period after the set and then rolls it all forward and repeats the process.
- This type of forward analysis is also related to well structured transition systems, but well-structuredness alone is not sufficient for such procedures to be complete ( for example, the coverability graph of a Petri net is always finite but in general, it overapproximates the true state space ).
- Coverability can be decided for any well-structured system, and so can reachability of a given control state, by the " backward algorithm " of Abdulla et al . e . g . in the case of unbounded Petri nets ) by a forward analysis based on a Karp-Miller coverability graph.
