Webdate HUIs which can show the trends [27], and mining on-shelf HUIs from the temporal databases [28]. Yun et al. [29] proposed a damped window to extract high average utility patterns over data streams. In contrast to static data, the dynamic data is more complex and desirable in many 1, :::,) >.). Webdata, but fewer works have integrated utility theory for mining high-utility patterns from event/sequence data. In this sec- tion, we separately present the prior works on SPM, HUIM, and HUSPM.

WebUtility-oriented pattern mining is an emerging topic, since it can reveal high-utility patterns from different types of data, which provides more information than the traditional frequency/confidence-based pattern mining models. Web1 de jan. de 2024 · On-shelf utility mining (OSUM) is a potential solution to these situations. Apart from the quantities and utilities (e.g., profits) of items in transactions, OSUM also considers the on-shelf time periods of the items. It can thus discover itemsets that have high utility in their various on-shelf time periods.
