WebHá 1 dia · The item b in the high-utility sequence t has negative values. Problem statement. The problem of HUSPM (high utility sequence pattern mining) is to find all HUSPs in a q -sequence-based database with a user-specified minimum utility threshold. In particular, the utility of certain items may be positive or negative. WebUtility-driven mining, a recently emerging branch of utility-based data science, has been widely applied because it considers both the utility factor and the quantity characteristic with ranges of patterns. However, most existing utility-mining algorithms assume that patterns always appear regardless of the period.
Web27 de ago. de 2024 · Thus, it saves time for merging utility-list operations and avoids memory consumption caused by retaining candidate sets. Recently, to deal with sequence data (Gan et al., 2024b; Wu et al., 2024a), Zhang et al. (Zhang et al., 2024b) studied the more complicated problem of on-shelf utility mining in sequence data. Web8 de nov. de 2016 · The library is written in Cython to take advantage of a fast C++ backend with a high-level Python interface. It supports constraint-based frequent sequential pattern mining. Here is an example that shows how to mine a sequence database while respecting an average constraint for the prices of the patterns found.

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.
