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...
K-means clustering is an unsupervised machine learning algorithm widely used for partitioning a given dataset into K groups (where K is the number of pre-determined clusters based on initial analysis). The algorithm operates on a simple principle of optimizing the within-cluster variance, commonly ...
We propose two new algorithms for clustering graphs and networks. The first, called K‑algorithm, is derived directly from the k-means algorithm. It a

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.

While past research has focused on portfolio selection based on fundamental analysis, technical analysis should also be considered when using machine learning to select a portfolio. Clustering is an unsuperviseddata miningapproach for grouping things based on their similarities. It's used to examine a...
Then, we propose an iterative K-means clustering algorithm to get a reasonable initial feasible solution that is used to train the DRL algorithm. We construct the DRL framework as a sequential decision-making process, where at each step of the algorithm, the agent decides whether the value of...
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...
