Bayesian OMA FormulationThis chapter develops Bayesian formulations in operational modal analysis for data of different natures, including synchronous data in a single setup (the conventional setting), data from multiple setups and asynchronous data in a single setup. Modeling assumptions and their justifications are discussed.作者: Urologist 時(shí)間: 2025-3-22 06:38

Bayesian Inferencefects how computations should be performed for making inference. Computational strategies for ‘globally identifiable’, ‘local identifiable’ and ‘unidentifiable’ situations are further discussed in individual sections. ‘Model class selection’ is also introduced, which is an important topic for validating models beyond system identification.作者: glucagon 時(shí)間: 2025-3-22 20:14 作者: 亞當(dāng)心理陰影 時(shí)間: 2025-3-22 21:15 作者: Asparagus 時(shí)間: 2025-3-23 03:53 作者: tenuous 時(shí)間: 2025-3-23 08:25
