From August 17th to 23rd 2019 the two Germany based Big Data Competence Centers ScaDS Dresden/Leipzig and BBDC held the fifth international summer school on Big Data and Machine Learning in Dresden. This time, the summer school bridged the gap between the research fields Big Data and machine learning, with contributions from many internationally well-known experts from various fields. The highly recognized program included key notes from IBM, NVIDIA, Intel, and speakers from academia of both competence centers BBDC and ScaDS Dresden/Leipzig as well as invited speakers. The topics span a wide range of topics around large scale and data intensive computing (Big Data) and exciting new trends in machine learning, such as uncertainty quantification, distributed machine learning and architectural optimization for deep learning. Almost sixty participants could not just take part and connect to the expert, but could also contribute a poster about own research activity in a poster session and during the whole week to trigger discussions between participants. As social activity an archery tournament brought fun and a contrast into the program as well as triggered some competition among the participants. Stay in touch with us about future activities, e.g.the Big Data and AI in Business Workshop @September 19.-20. in Leipzig!
