Towards Target High-Utility Itemsets

no code implementations9 Jun 2022 Jinbao Miao, Wensheng Gan, Shicheng Wan, Yongdong Wu, Philippe Fournier-Viger

In this paper, we address this issue by proposing a novel list-based algorithm with pattern matching mechanism, named THUIM (Targeted High-Utility Itemset Mining), which can quickly match high-utility itemsets during the mining process to select the targeted patterns.

Towards Target Sequential Rules

no code implementations9 Jun 2022 Wensheng Gan, Gengsen Huang, Jian Weng, Tianlong Gu, Philip S. Yu

In this paper, we provide the relevant definitions of target sequential rule and formulate the problem of targeted sequential rule mining.

Smart System: Joint Utility and Frequency for Pattern Classification

no code implementations9 Jun 2022 Qi Lin, Wensheng Gan, Yongdong Wu, Jiahui Chen, Chien-Ming Chen

Big data technologies such as design making, event detection, and classification are developed to help manufacturing organizations to achieve smart systems.

Towards Revenue Maximization with Popular and Profitable Products

no code implementations26 Feb 2022 Wensheng Gan, Guoting Chen, Hongzhi Yin, Philippe Fournier-Viger, Chien-Ming Chen, Philip S. Yu

To fulfill this gap, in this paper, we first propose a general profit-oriented framework to address the problem of revenue maximization based on economic behavior, and compute the 0n-shelf Popular and most Profitable Products (OPPPs) for the targeted marketing.

TaSPM: Targeted Sequential Pattern Mining

no code implementations26 Feb 2022 Gengsen Huang, Wensheng Gan, Philip S. Yu

What's more, to improve the efficiency of TaSPM on large-scale datasets and multiple-items-based sequence datasets, we propose several pruning strategies to reduce meaningless operations in mining processes.

Flexible Pattern Discovery and Analysis

no code implementations24 Nov 2021 Chien-Ming Chen, Lili Chen, Wensheng Gan

Based on the analysis of the proportion of utility in the supporting transactions used in the field of data mining, high utility-occupancy pattern mining (HUOPM) has recently attracted widespread attention.

TargetUM: Targeted High-Utility Itemset Querying

no code implementations30 Oct 2021 Jinbao Miao, Shicheng Wan, Wensheng Gan, Jiayi Sun, Jiahui Chen

The algorithm uses a lexicographic querying tree and three effective pruning strategies to improve the mining efficiency.

FRI-Miner: Fuzzy Rare Itemset Mining

no code implementations11 Mar 2021 Yanling Cui, Wensheng Gan, Hong Lin, Weimin Zheng

In some cases, infrequent or rare itemsets and rare association rules also play an important role in real-life applications.

On the Construction of a Post-Quantum Blockchain for Smart City

no code implementations31 Dec 2020 Jiahui Chen, Wensheng Gan, Muchuang Hu, Chien-Ming Chen

In addition, traditional proof of work (PoW)-based consensus protocols such as Bitcoin cannot supply memory mining, and the transaction capacity of each block in a blockchain is limited and needs to be expanded.

Discovering High Utility-Occupancy Patterns from Uncertain Data

no code implementations18 Aug 2020 Chien-Ming Chen, Lili Chen, Wensheng Gan, Lina Qiu, Weiping Ding

To find patterns that can represent the supporting transaction, a recent study was conducted to mine high utility-occupancy patterns whose contribution to the utility of the entire transaction is greater than a certain value.
