Title: Learning better models for inverse problem in imaging

Abstract: In this talk, I will present our ongoing activities in learning better models for inverse problems in imaging. We consider classical variational models used for inverse problems but generalized these models by introducing a large number of free model parameters. We learn the free model parameters by minimizing a loss function comparing the reconstructed images obtained from the variational models with ground truth solutions from a training data base. I will also show recent results on learning “deeper” regularizers that are allowed to change their parameters in each iteration of the algorithm. We show applications to different inverse problems in imaging where we put a particular focus on image reconstruction from undersampled MRI data.

Title: On Quantum Computing, Kurzweil Singularity and Beyond

Abstract: Successes of the twentieth century physics and electronics made a huge impact on our society: from space technology to improved medical tools to colossal advancements in computing … And, while we still do not understand complex cooperative phenomena in the nanoscale limit, we nevertheless have ever more advanced software and over 6 billion smartphones! Moreover, in this early 3rd Millenium, we face huge challenges: Many timely, relevant themes are discussed here at the 2018. International Conference on Smart Systems and Technologies, yet I will deliberately discuss somewhat broader vision. Fast advancements in Quantum Computing (QC) and Artificial Intelligence (AI), beyond the Kurzweil singularity, are very competitive fields, and we will consider some latest examples and emerging trends. And I am happy to admit that we cannot as yet provide all coherent answers in QC or AI, so there are great opportunities for our new generations!

Title: Research Methods and Examples of Research in Distributed Systems Security

Abstract: Over the past few years an increasing number of descriptive works have helped explain complex phenomena in the area of distributed systems security. These include the efficiency of spam campaigns, the distribution of bots, or the likelihood of users to accept false identities as friends in social networks. Studies in this field are characterized by the necessity of empirical research based on observing, describing and inferring the behaviour of complex systems.

Future research in the area of distributed systems security, including my own work, will use empirical research to complement design science as research method. Specifically, this approach consists of 1) passively observing large systems; (2) active probing that stimulates revealing behaviour of the systems; (3) developing solutions for relevant security problems; (4) and evaluating these contributions. Its impact on a large number of users makes this area of research relevant and urgent. By following the described methodology, it will be possible to improve security in an existing ecosystem in which changes can be deployed only over a long period of time.
