Type of Contributions:
The journal welcomes the following types of contributions.

Original research articles:
Research articles should not exceed 30 pages (single column, double spaced, including figures, tables and references) in length and must contain novel research within the scope of the journal.

Review articles:
Review articles are typically 30-60 pages (single column, double spaced, including figures tables and references) in length, and provide a comprehensive review on a scientific topic. They may be relatively broad in scope, thereby serving a tutorial function, or be quite specialized, aimed at researchers in the chosen field.

Such articles should not exceed 10 pages (single column, double spaced, including figures, tables and references) in length. The objective is to provide detailed, constructive feedback on submitted papers and publish high quality papers within a very short period of time.

Special Issue on Clustering for Signal Processing: Challenges, Advances, and Emerging Applications
提出日: 2026-08-31

Clustering serves as a fundamental technique in signal processing and unsupervised learning, playing a crucial role in uncovering hidden structures and patterns within complex signals. Its broad applicability has made it an indispensable tool in diverse domains, including speech and audio processing, biomedical signal analysis, remote sensing, and wireless communications. From separating audio sources in speech enhancement to classifying hyperspectral remote sensing images, clustering methods have significantly impacted both academic research and real-world signal processing applications.

However, as signal data continues to grow in volume, complexity, and diversity, traditional clustering methods face substantial challenges. High-dimensional signal representations, time-varying environments, and multi-modal data sources demand algorithms that are adaptive, scalable, and capable of delivering robust performance under uncertain conditions. Moreover, the interpretability of clustering results has become increasingly critical, particularly in applications such as brain signal analysis, healthcare diagnostics, and cybersecurity.

Recent advancements in clustering methodologies have sought to address these challenges by leveraging deep learning, graph signal processing, self-supervised learning, and optimization-driven frameworks. Meanwhile, the applications of clustering in signal processing have expanded into emerging areas, including IoT-based sensor networks, multi-channel biomedical monitoring, and intelligent communication systems.

This special issue aims to bring together cutting-edge research on clustering techniques specifically tailored for signal processing, with a focus on theoretical advancements, novel methodologies, and practical applications. We invite high-quality submissions that address the challenges of clustering in complex signal environments, particularly in dynamic, multi-view, high-dimensional, and large-scale signal data settings. By fostering a platform for sharing innovative approaches and interdisciplinary applications, this special issue seeks to advance clustering as a crucial tool in modern signal processing, artificial intelligence, and data science.

Topics of interest for this special issue include, but are not limited to:

    Theoretical advancements in clustering methodologies for signal processing
    Clustering techniques for high-dimensional and large-scale signal data
    Dynamic and online clustering for time-series and streaming signals
    Multi-modal and multi-view clustering for heterogeneous signal sources
    Robust clustering for noisy and corrupted signal data
    Graph-theoretical clustering methods in signal representation and analysis
    Interpretable and explainable clustering techniques in signal processing applications
