The performance of multilabel learning depends heavily on the quality input features. A mass irrelevant and redundant features may seriously affect learning, feature selection is an effective technique to solve this problem. However, most methods mainly emphasize removing these useless features, exploration interaction ignored. Moreover, widespread existence real-world data with uncertainty, ambiguity, noise limits selection. To end, our work dedicated designing efficient robust scheme. First, distribution character analyzed generate fuzzy multineighborhood granules. By exploring classification information implied in under granularity structure, a $k$ -nearest neighbor rough set model constructed, concept dependency studied. Second, series uncertainty measures approximation spaces are studied analyze correlations pairs, including interactivity. Third, by investigating measure between label, modeled as complete weighted graph. Then, vertices assessed iteratively guide assignment weights. Finally, graph structure-based algorithm (GRMFS) designed. experiments conducted 15 datasets. results verify superior GRMFS compared nine representative methods.

Outlier Detection Using Three-Way Neighborhood Characteristic Regions and Corresponding Fusion Measurement

IEEE Transactions on Knowledge and Data Engineering, Год журнала: 2023, Номер 36(5), С. 2082 - 2095

Опубликована: Сен. 5, 2023

Outliers carry significant information to reflect an anomaly mechanism, so outlier detection facilitates relevant data mining. In terms of detection, the classical approaches from distances apply numerical rather than nominal data, while recent methods on basic rough sets deal with data. Aiming at wide numerical, nominal, and hybrid this paper investigates three-way neighborhood characteristic regions corresponding fusion measurement advance detection. First, are deepened via decision, they derive structures model boundaries, inner regions, regions. Second, motivate weight regarding all features, thus, a multiple factor emerges establish new method detection; furthermore, algorithm (called 3WNCROD) is designed comprehensively process mixed Finally, 3WNCROD experimentally validated, it generally outperforms 13 contrast algorithms perform better for

Abstract Outlier detection is a widely used technique for identifying anomalous or exceptional events across various contexts. It has proven to be valuable in applications like fault detection, fraud and real-time monitoring systems. Detecting outliers real time crucial several industries, such as financial quality control manufacturing processes. In the context of big data, amount data generated enormous, traditional batch mode methods are not practical since entire dataset available. The limited computational resources further compound this issue. Boxplot algorithm outlier that involves derivations. However, lack an incremental closed form statistical calculations during boxplot construction poses considerable challenges its application within realm data. We propose incremental/online version address these challenges. Our proposed based on approximation approach numerical integration histogram calculation cumulative distribution function. This independent dataset’s distribution, making it effective all types distributions, whether skewed not. To assess efficacy algorithm, we conducted tests using simulated datasets featuring varying degrees skewness. Additionally, applied real-world concerning software which posed challenge. experimental results underscored robust performance our highlighting comparable access dataset. online method, leveraging define whiskers, consistently achieved results. Notably, demonstrated efficiency, maintaining constant memory usage with minimal hyperparameter tuning.
