Title of the Talk: Hybrid Digital-Analog Number Representation in Computing and in Nature.

Abstract:  The discovery that mammals use a multi-modular method akin to residue number system (RNS), but with continuous residues or digits, to encode position information led to the award of the 2014 Nobel Prize in Medicine. After a brief review of the evidence in support of this hypothesis, and how it relates to RNS, I discuss the properties of continuous-digit RNS, and discuss results on the dynamic range, representational accuracy, and factors affecting the choice of the moduli, which are themselves real numbers. I then take a step back and briefly explore hybrid digital-analog number representations and their robustness and noise-immunity advantages more generally. I conclude with suggestions for further research on important open problems in the domain of hybrid digital-analog number representation and processing.

Title of the Talk: Security for Quantum Networks

Abstract: Quantum networks enhance information-and-communication technology through applications such as secure quantum computing on the cloud, quantum-enhanced high-precision clock synchronization and quantum-enhanced key distribution. Reliable and efficient functioning of a quantum network depends on identifying and mitigating security risks originating within and outside the network. We introduce a comprehensive framework for developing and assessing secure quantum networks. In particular, we articulate issues for making quantum networks secure in general,  summarise the state of the art and identify priority directions for further investigation. Our analysis builds on secure communication protocols developed for classical layered network architectures such as the open-systems interconnection (OSI) model and the transmission control protocol/internet protocol (TCP/IP) model. Our work could enable development of a hardware-independent framework for securing general quantum networks that allows developers to identify mandatory security mechanisms and incorporate additional security requirements for clients during network design.

Title of the Talk: "Understanding Language'' with Deep Learning

Abstract:  The last ten years have witnessed an enormous increase in the application of deep-learning methods to both spoken and textual natural language processing, often with hand-wavy appeals to cognitive
neuroscience.  Have they actually advanced the state of the art in "understanding" language?  Initial successes with respect to some well-defined tasks such as language modelling and acoustic modelling cleared the way for such claims, but attempts to extend this progress to other feats that might follow from genuine natural language understanding have been more problematic --- often because of sloppy evaluations or poorly chosen baselines.
This talk will consider three of these feats in detail: grammatically judgements, acoustic filter banks, and text-to-speech synthesis.  We will discuss the consequences of empirically grounding the evaluation and the choice of inferential statistics versus more engineering-oriented correlation and accuracy scores.

Title of the Talk: New Generation of Social Context-based Biometric Multi-modal Systems 

Abstract:  Human identity recognition is one of the key mechanisms of ensuring proper asset and information access to individuals, which is the base of many government, social services, consumer, financial and recreational activities in the society. Biometrics are also increasingly used in a cybersecurity context to mitigate vulnerabilities and to ensure protection against an unauthorized access or estimate risk level.

This keynote lecture discusses a new type of biometric information – Social context-based biometrics, that can be harvested from publicly available data in an on-line domain. Using advanced machine learning and pattern recognition methods, a fairly accurate profile of social network users can be established and then used to identify a user, their preferences or even their gender. The lecture will describe the developed multi-modal prototype system that can extracts specific spatial, temporal, behavioral, soft, and even aesthetic information based on social networks activities. It will conclude with practical case studies and discussion of challenges in the area of social biometrics.

Title of the Talk: Algorithmic thinking for Computational Public Safety (CPS)

Abstract: Public Safety refers to the welfare and protection of the general public. It is usually expressed as a governmental responsibility involving organizations providing security, fire, and medical services. These services have always used informal algorithms to perform their functions but with the advent of cheap, readily available computation and digital network resources, increasingly these algorithms have become more complex and formalized to the point where they can be expressed in ways commonly used to describe computer programs. In this presentation, Dr. Ferworn will discuss some of the real world challenges he has faced in his work with CPS tasks and algorithms as varied as those for search and rescue, improvised explosive device modeling and neutralization and patient health record quality assurance.

Title of the Talk: Hyper-Realistic Imaging for Enhanced Quality of Experience

Abstract: Producing truly realistic and immersive digital imaging is widely seen as the ultimate goal towards further improving Quality of Experience (QoE) for end users of multimedia services. The human visual system is able to perceive a wide range of colors, luminous intensities, and depth, as present in a real scene. However, current traditional imaging technologies cannot capture nor reproduce such a rich visual information. Recent research innovations have made it possible to address these bottlenecks in multimedia systems. As a result, new multimedia signal processing areas have emerged such as ultra-high-definition, high frame rate, high dynamic range imaging, light fields, and point cloud.

These technologies have the potential to bring a leap forward for upcoming multimedia systems. However, the effective deployment of hyper-realistic video technologies entails many technical and scientific challenges. In this talk, I will discuss recent research activities covering several aspects of hyper-realistic imaging, including point cloud compression, light field compression, and semantic-aware tone mapping for high dynamic range imaging.
