“…However, recent studies have shown that hybrid feature selection methods can simultaneously take advantage of the efficiency advantages of filter method and the accuracy advantages of warpper method to achieve superior performance [44]. In addition, some studies have also studied the data imbalance problem common in microarray datasets [45,46].…”

“…A recently developed density-based clustering approach, namely FPS-clustering [31], is used to explore the cluster structure of data without any prior knowledge or parameter optimization. In [26], the authors extended FPS-clustering to feature clustering analysis for completely continuous or discrete features by proposing two different cluster merge schemes. Hence, we develop a new feature clustering approach by integrating the FPS-clustering with a universal cluster merge strategy, which can be applied to both continuous and discrete features.…”

“…Several recent filter-based feature selection approaches attempted to reduce feature redundancy through feature clustering analysis [22]- [26]. Features are separated into a set of clusters based on their similarity such that highly redundant features are grouped together.…”
