Call for Papers Special Issue "Machine Learning Approaches in Big Data Visualization" IEEE Computer Graphics and Applications (CG&A) https://bit.ly/37EaNcn Data visualization is now one of the cornerstones of data science, turning the abundance of big data being produced through modern systems into actionable knowledge. Data visualization in the big data era raises the need to co-design and more closely align the underlying data management systems with the user-oriented techniques that state-of-the-art visualization systems now offer. Several solutions from those two communities are revisited with big data in mind, such as efficient data storage, adaptive indexing for enabling visual interaction and visual analytics, machine learning (ML)-driven visualization and new ways for visual presentation of massive data, and personalization and automation techniques that can fit to different users’ needs. Overall, modern visualization systems start integrating scalable techniques to efficiently support complex ML-based analysis over billion-object datasets, while limiting the visual response to a few milliseconds. This special issue aims to publish novel works on multidisciplinary research areas spanning from data management and ML to visualization and human-computer interaction.
