Phm algorithm
Prognostic performance evaluation is of key importance for a successful PHM system deployment. The early lack of standardized methods for performance evaluation and benchmark data-sets resulted in reliance on conventional performance metrics borrowed from statistics. Those metrics were primarily accuracy and precision based where performance is evaluated against end of life, typically known a priori in an offline setting. More recently, efforts towards m… WebbTo monitor the start sequence of turbofan engines, a PHM algorithm has been developed. It is called ESC for Engine Start Capability. The anomaly detection phase is performed …

WebbAn e cient algorithm named PHM (Peri- odic High-utility itemset Miner) is proposed to e ciently enumerate all periodic high-utility itemsets. Experimental results show that the PHM algorithm is e cient, and can lter a huge amount of non periodic pat- terns to reveal only the desired periodic high-utility itemsets.
