Special Issue Information

Dear Colleagues,

We are pleased to announce a call for contributions to this Special Issue entitled "Advances in Data Analysis and Visualization". This Special Issue aims to bring together the latest research and developments in the field, offering new insights and methodologies that advance the state-of-the-art in data analysis and visualization techniques.

The ever-increasing volume and complexity of data in various domains have necessitated the development of more sophisticated methods for analysis and visualization. Effective data visualization not only aids in understanding complex datasets but also plays a crucial role in decision-making processes. This Special Issue is dedicated to exploring innovative approaches that push the boundaries of traditional data analysis and visualization methods. By providing a platform for the dissemination of cutting-edge research, we aim to contribute to the ongoing dialogue on how to better manage, interpret, and present data in a way that is both meaningful and actionable.

The purpose of this Special Issue is to explore the intersection of data analysis and visualization, focusing on new tools, techniques, and applications that enhance our ability to interpret complex datasets. This aligns with the broader mission to publish high-quality research that advances the field of data science. We encourage submissions that address the theoretical and practical challenges in data visualization, offer novel insights, or present case studies that demonstrate the impact of advanced visualization techniques in real-world scenarios.

We welcome original research articles and review papers in, but not limited to, the following areas:

  • Innovative data visualization techniques for large and complex datasets;
  • Integration of machine learning and visualization for enhanced data analysis;
  • Interactive and immersive visualization environments;
  • Visualization of high-dimensional data;
  • Real-time data visualization and analysis;
  • Applications of visualization in specific domains (e.g., healthcare, finance, and the social sciences);
  • Visualization techniques for time-series data;
  • Visual analytics and human–computer interactions;
  • Best practices and challenges in data visualization;
  • Comparative studies of visualization tools and methodologies.

We look forward to receiving your valuable contributions to this Special Issue. Your participation will be instrumental in shaping the future direction of research in data analysis and visualization.

Thank you for considering our invitation.

Traffic accidents remain a major challenge for intelligent transportation systems, requiring reliable and real-time detection under complex visual conditions. This study aims to investigate how backbone-level architectural modifications affect traffic accident detection performance in video-based scenarios. A dataset of 250 accident videos was curated from a public traffic surveillance source. This resulted in approximately 3000 manually annotated frames covering diverse accident conditions such as motion blur, occlusion, and illumination variation. To improve detection performance, we introduce Cross Stage Partial (CSP)-based feature partitioning and extend Efficient Layer Aggregation Network (ELAN) structures within the YOLOv9 backbone. Experimental evaluation demonstrates that the CSP-enhanced YOLOv9-t model achieves the best performance among all tested variants, improving mAP50 from 0.35 to 0.50 (approximately 42.8% relative improvement) compared to the baseline YOLOv9-t model, while maintaining real-time inference speed. The results further reveal that CSP improves localization precision, whereas ELAN enhances recall, highlighting complementary behaviors of backbone-level modifications in traffic accident detection tasks. These findings provide insights into how targeted architectural refinements can improve detection robustness in challenging real-world traffic scenarios. Full article

Forecasting GDP is a highly practical task in macroeconomics, especially in the context of rapidly changing economic environments caused by both economic and non-economic factors. This study proposes a deep learning model that integrates Long Short-Term Memory (LSTM) networks with a phase-adaptive attention mechanism (PAA-LSTM model) to improve forecasting accuracy. The attention mechanism is flexibly adjusted according to different phases of the economic cycle—recession, recovery, expansion, and stagnation—allowing the model to better capture temporal dynamics compared to traditional static attention approaches. The model is evaluated using GDP data from six countries representing three groups of economies: developed, emerging, and developing. The experimental results show that the proposed model achieves superior accuracy in countries with strong cyclical structures and high volatility. In more stable economies, such as the United States and Canada, PAA-LSTM remains competitive; however, its margin over simpler models is narrower, suggesting that the benefits of added complexity may vary depending on economic structure. These findings underscore the value of incorporating economic cycle phase information into deep learning models for macroeconomic forecasting and suggest a promising direction for selecting flexible forecasting architectures tailored to different country groups.
