In today's world, Big data analytics and stream processing have taken great hype due to the digitization of the environment along with the integration of smart data computing services and interconnectivity. This digitized world offers huge applications especially in the fields of agriculture, healthcare, smart education, economy, energy, industry, and a lot more. Most of the required data is gathered by the countless number of sensor devices being applied in the vicinity of humans to identify certain activities or scenarios. In order to process such a huge never-ending stream of data, there is a need to re-think the way data is processed for both cases i.e. data-at-rest and data-in-motion. In order to have knowledge about the latest trend in this field, in this IEEE CIS Summer School on Big data analytics and stream processing is aimed at highlighting the tools, techniques, and applications from the perspective of future intensive applications. To serve this purpose, this IEEE CIS Summer School features a large number of keynote speakers/plenary/invited talks on advanced topics and also offers a good platform for the participants for the innovative and entrepreneurial ideas.
