WebbPHM is an algorithm for discovering periodic high-utility itemsets. An itemset is a group of items. The PHM algorithm finds itemsets that appears periodically in a sequence of transactions and generate a high profit (have a high utility). To measure if an itemset is periodic, the algorithm calculates its periods. shannon staley and sons

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… WebbThe PHM algorithm is performed during product screening tests, diagnostic processes, or after the manufacturer process.
