@misc{16688, author = {P{\r a}l Halvorsen}, title = {From a need, to an idea, to a complete system: a perspective based on real-world applications}, abstract = {Researchers and developers have been talking about what determines a good system in various aspects for a long time, and eventually, it is all about quality. We are interested in quality throughout the entire holistic system, from data production to data consumption, and we have for several years aimed to solve real-world problems with a focus on both functional and non-functional requirements. This includes optimizing the various steps of both workflow and computing pipelines.In this talk, we will address quality at various levels and aspects within a holistic system. We will highlight some examples starting from challenges in society, using sports and health as showcases, via researching solutions where we optimize workflows, system performance and user experiences, to observations of real use and deployments of the systems. In particular, the talk will cover a video and metadata system for commercial sport production and dissemination as an integrated, next generation live streaming and archive system. We will also use an example from an AI-based medical computer assisted diagnosis system to detect anomalies during colonoscopy examinations. The talk will look at various solutions and the state of the art, and will conclude with various open challenges.}, year = {2022}, journal = {IEEE/ACM International Symposium on Quality of Service (virtual)}, month = {06/2022}, publisher = {IEEE}, url = {https://iwqos2022.ieee-iwqos.org/program/keynote/}, }
