Batch Process Modeling and Monitoring With Local Outlier Factor

IEEE Transactions on Control Systems Technology, 2019
Batch processes are commonly involved by a succession of working phases with implicit non-Gaussian behaviors. Besides, in most cases, batch-to-batch processes also show similar but yet not identical running trajectory variations. To deal with these issues, this paper introduces a systematic analysis flowchart based on local outlier factor (LOF) for ...

Local peculiarity factor and its application in outlier detection

Proceedings of the 14th ACM SIGKDD international conference on Knowledge discovery and data mining, 2008
Peculiarity oriented mining (POM), aiming to discover peculiarity rules hidden in a dataset, is a new data mining method. In the past few years, many results and applications on POM have been reported. However, there is still a lack of theoretical analysis.

Adaptive fuzzy C-means clustering integrated with local outlier factor

Intelligent Data Analysis, 2022
The conventional fuzzy C-means (FCM) is sensitive to the initial cluster centers and outliers, which may cause the centers deviate from the real centers when the algorithm converges. To improve the performance of FCM, a method of initializing the cluster centers based on probabilistic suppression is proposed and an improved local outlier factor is ...

Weighted Local Outlier Factor for Detecting Anomaly on In-Vehicle Network

2020 16th International Conference on Mobility, Sensing and Networking (MSN), 2020
Modern vehicles are generally equipped with dozens of (or even hundreds of) electronic and intelligent devices and bloom into more involved information hub in enabling V2X networking. Protecting this increasingly complex vehicle ecosystem can be an arduous task, especially as the proliferation of data across distinct connected devices makes them more ...
