Objective: Utilize k-means clustering to segment customers of a mall based on their spending behavior, aiming to provide personalized services and improve marketing strategies. Dataset: Use the "Mall Customer Segmentation Data" available on the UCI Machine...
However, instead of using linear programming in the assignment phase, we formulate the partitioning as a pairing problem [7], which can be solved optimally by Hungarian algorithm in O(n3) time.

A Sparse K-Means Clustering Algorithm Name: *** ID: *** K-means is a broadly used clustering method which aims to partition observations into clusters, in which each observation belongs to the cluster with the nearest mean. The popularity of K-means derives in part from its conceptual simpl...
It confirms that balanced clustering is effective for learning representations. If de- creasing the ratio, each cluster can have a different number of instances that is more flexible to capture the inherent data structure. For example, when γ′ = 0.8, the m...
For example, the work in [11] proposes a multiple kernel k-means clustering algorithm with a matrix-induced regularization term to re- duce the redundancy of the selected kernels. A local kernel alignment variant is then developed by sufficiently consid- ering the variation among sample, which ...
The multiple kernel learning technique and K-means clustering which is used to forecast stock price changes and incorporate information from the target company and its homogenous cluster. The experiment was conducted utilizing three years of data from the Republic of Korea. The results reveal that ...

After clustering, each sensor node is grouped into a subcluster; for example, S 1 3 indicates that sensor S 1 is a member of subcluster C 3 (Figure 3). Figure 3. Sensor clustering using the K-means algorithm, with optimal number of clusters K = 4 . Table 3. Centroids after ...
