In recent years, the amount of data collected worldwide are increasing exponentially and simultaneously this big data paradigm will also demand to enhance the process of data analysis, storage and management. Nevertheless, the relevant research areas like machine learning, artificial intelligence, deep learning, and data intelligence are revolutionizing both society and business paradigm. In this perspective, the International Conference on Pervasive and Data Intelligence [ICPDI 2021] presents a platforms for data science researchers to discuss and state-of-the-art research works, challenges, and the applications that deploy potential transition towards more intelligent and data-intensive applications. ICPDI 2021 aims to investigate the rapidly evolving area of data analytics, big data and data intelligence that encompass machine learning, data science, and business intelligence.
