Lajos Hanzo

Aeronautical Ad-Hoc Networking for the Internet-above-the-clouds


ABSTRACT: As a promising system-architecture, an integrated terrestrial, UAV-aided, airplane-assisted as well as satellite-based global coverage-solution and its enabling techniques will be highlighted as a further step towards the provision of seamless global coverage.

An open scientific challenge is that of striking the most appropriate trade-off amongst the conflicting performance metrics of throughput, transmit power, latency, error probability - just to name a few. The 5G system meets this challenge by introducing three modes of operations, namely the enhanced Mobile BroadBand (aMBB), the Ultra Reliable Low-Latency Communications (URLLC) and the massive Machine Type Communications (mMTC) modes.

However, further research is required for findig all the optimal operating points of wireless systems with the aid of sophisticated multi-component system optimization, leading to the Pareto-front of all optimal solutions.

Bad Data Analysis in An Era of Big Data


ABSTRACT: In this talk, we discuss another side of big data analysis, bad data analysis, where the badness means the complexities resulting in the reproducibility issues. Some background knowledge is first introduced on the volatility of the big data analysis, which shows 1) “big” does not necessarily mean “better” and 2) the so-called multi-objective data analysis (against badness) is vitally important in advancing the state-of-the-art. Two examples are used for demonstration of the big data analysis, one for big data from complex networks and the other for big data from gene expression image processing. Finally, conclusions are drawn and some future directions are pointed out.

New Generation of Internet of Things Architecture, Services and Ecosystems


ABSTRACT: The Internet of Things (IoT) aims at connecting myriads of data collecting devices deployed at physical locations in the field. Traditionally, a custom set of such devices would collect data sets specifically targeted to one type of application usually hosted in the cloud; another application would require another set of sensors and so on, thus leading to stove-piped solutions and introducing major management complexity. The Data Exchange paradigm aims at a horizontal approach, where sensors collect data which becomes a reusable resource among a plurality of applications removing the dedicated sensor-data-app vertical model. Moreover, modern data processing techniques including AI, machine learning and a variety of different analytics, such as video analytics, drives the development of innovative IoT applications and services which, due to Data Exchange, may combine, correlate and analyse data from more than one source driving higher value insights from low-level data. Another noteworthy dimension is introduced by the “IoT Continuum”. IoT Continuum characterises the spread of hosting compute infrastructures from the very customer edge, where devices are situated such as general-purpose gateways, the network edge, e.g., 5G MEC nodes, all the way to the cloud, and anywhere in between the edge and cloud ends where compute nodes are available. These new techniques driving IoT service development as well as the IoT Continuum define the New Generation of IoT Architecture (NG-IoTA), on which this talk will be focusing. We will present a set of architectural principles underpinning NG-IoTA, talk about the manifestation of these principles in various solutions regarding Edge Computing, orchestration, IoT analytics, service management and their application in a few use-cases offering real world example implementations of these capabilities.

Federated Learning Systems: A New Holy Grail for System Research in Data Privacy and Protection?


ABSTRACT: Federated learning has been a hot research area in enabling the collaborative training of machine learning models among different organizations under the privacy restrictions. As researchers try to support more machine learning models with different privacy-preserving approaches, there is a requirement in developing systems and infrastructures to ease the development of various federated learning algorithms. Just like deep learning systems such as Caffe, PyTorch, and Tensorflow that boost the development of deep learning algorithms, federated learning systems are equivalently important, and face challenges from various issues such as unpractical system assumptions, scalability and efficiency. Inspired by federated systems in other fields such as databases and cloud computing, we study the system design requirements for federated learning systems. We find that two important features for federated systems in other fields, i.e., heterogeneity and autonomy, are rarely considered in the existing federated learning systems. In this talk, we will take a systematic comparison among the existing federated learning systems and present our research progress and future system research opportunities and directions.
