NettetAs a popular clustering algorithms, fuzzy c-means (FCM) algorithm has been used in various fields, including fault diagnosis, machine learning. To overcome the sensitivity to outliers problem and the local minimum problem of the fuzzy c-means new algorithm is proposed based on the simulated annealing (SA) algorithm and the genetic algorithm … Nettet28. mai 2024 · The health monitoring and management have been accepted in modern industrial machinery for an intelligent industrial production. To timely and reliably assess the bearing performance degradation, a novel health monitoring method called feature clustering analysis (FCA) has been proposed in this study. Along with the working time …

Nettet25. apr. 2024 · In bearing fault diagnosis, due to the insufficient obtained supervised data and the inevitable noise contained in the vibration signals, the problem of clustering bearing fault diagnosis with imbalanced data containing noise is caused. Thanks to the ability to quickly and fully learn boundary information in small samples, the extension … Nettet22. jun. 2024 · The approach is divided into three parts: the first part is the clustering to detect the damage state by the density-based spatial clustering of applications with noise. The second one is the health indicator construction which could give a better reflection of the bearing degradation tendency and is selected as the input for the prediction model.
NettetThe first approach relies on statistical clustering of the intersections of line-of-bearing measurements and the second approach exploits cyclostationary features of the … NettetK-means clustering produces a Voronoi diagram which consists of linear decision boundaries. For example, this presentation depicts the clusters, the decision boundaries (slide 34) and describes briefly the Voronoi diagrams, so you can see the similarities. On the other hand, neural networks depending on the number of hidden layers are able to ...

NettetAbstract: In the on-line monitoring for the fault of rolling bearing, we have no information about the cluster number of the obtained data signal, which cause great challenges for on-line fault diagnosis when using clustering algorithms. In this paper, we extract three features of the vibration signals of rolling bearings as the parameters in time-domain, … sims 4 hair mods downloadNettet10. nov. 2015 · If the point can be belong to two lines, it should belong to the strongest. A line is considered stronger that another when it has more belonging points. The algorithm should not cover all points because they may be outliers. The space contains many outliers it may hit 50% of the the total space.
