This work introduces a new clustering algorithm based on Self-Organizing Maps (SOM) that simultaneously learns the structure of data and its segmentation. The proposed Density-based Simultaneous Two-Level SOM (DS2L-SOM) effectively addresses the challenge of determining an appropriate number of clusters without prior knowledge by leveraging both density and distance in the clustering process. The algorithm demonstrates superior performance in clustering complex and irregular datasets, making it a robust tool for unsupervised learning.
