s200_trevor-hogan

Title: Data and Dasein – A Phenomenology of Human-Data
Relations.

Abstract: In contemporary society, data representation
is an important and essential part of many aspects of our daily lives.
In this talk Trevor will present how his doctoral research has
contributed to our understanding on how people experience data and what
role representational modality plays in the process of perception and
interpretation. This research is grounded in phenomenology – he aligns
his theoretical exploration to ideas and concepts from philosophical
phenomenology, while also respecting the essence of a phenomenological
approach in his choice and application of methods. Alongside offering a
rich description of people’s experience of data representation, the key
contributions of his research transcend four areas: theory, methods,
design, and empirical findings. From a theoretical perspective, besides
describing a phenomenology of human-data relations, he has defined, for
the first time, multisensory data representation and established a
design space for the study of this class of representation. In relation
to methodologies, he will describe how he deployed two elicitation
methods to investigate different aspects of data experience. He blends
the Repertory Grid technique with a focus group session and shows how
this adaption can be used to elicit rich design relevant insight. He
will also introduce the Elicitation Interview technique as a method for
gathering detailed and precise accounts of human experience.
Furthermore, he will describe how this technique can be used to elicit
accounts of experience with data. In his talk Trevor will present the
findings of a series of empirical studies, these show, for instance, how
certain representational modalities cause us to have heightened
awareness of our body, some are more difficult to interpret than others,
some rely heavily on instinct and each of them solicit us to reference
external events during the process of Interpretation.

Biography: Trevor Hogan is a Lecturer of Interaction
Design at the Cork Institute of Technology, Ireland. The aim of his
research is to describe and better understand how embodiment influences
and augments people’s experience of data representations. His work is
strongly interdisciplinary and may be situated in the field of
interactive design, but at the intersection of tangible computing,
human-computer interaction, information visualization and psychology. At
CIT Trevor leads the Human-Data Interaction Group, a multidisciplinary
research team, whose aim is explore novel ways of representing data –
through and beyond the visual modality. This group is also focused on
exploring methods and approaches that broaden the evaluation criteria of
data representation – beyond traditional measurements, such as
efficiency and effectiveness, towards novel aspects such as experience,
use qualities, hedonics, affect, empathy, and enchantment.

Quicker Sort by Dietmar Kühl, Bloomberg L.P.

 

Abstract:

Quicksort is a well-known sorting algorithm used to implement sort functionality in many libraries. The presentation isn’t really about the algorithm itself but rather about how to actually create an efficient implementation of the algorithm: a text-book implementation of the algorithm actually is not that quick (even if the pivot is chosen cleverly). It takes paying some attention to detail to improve the implementation significantly. This presentation starts with a simple implementation and makes incremental improvements to eventually yield a proper generic and fast sorting function. All code will be in C++ but it should be possible to follow the majority of the reasoning with knowledge of another programming language.

Running Before We have Evolved Legs: The Gap Between Theory and Practice in Evolutionary Algorithms by Prof. John McCall

Abstract:

Evolutionary algorithms (EA) has developed as an academic discipline since the 1960s. The subject has spawned major subfields such as swarm intelligence and genetic programming and is applied to a wide variety of practical real world problems in science medicine and engineering. EAs are often the only practical method of solving large combinatorial optimisation problems and have achieved best-known results on a variety of benchmark problems. The global academic EA community is highly active, supporting several large international conferences and high-quality international journals. Despite this activity, sustained over decades, the community has struggled to make significant progress on developing a satisfactory theory of EAs. At the same time, substantial progress has been made on developing more sophisticated EAs that are ever more powerful but ever less amenable to theoretical study. In this talk I will outline some of the main approaches to a theory of EAs and illustrate the gap between those EAs that can be theoretically analysed by those approaches and EAs that are being used in practice. I will conclude with some interesting current developments and key open questions.

SACHI Seminar: Professor Chris Reed – Argument Technology and Argument Mining

creed

Title:  Argument Technology and Argument Mining

Chris Reed, Centre for Argument Technology, University of Dundee – http://arg.tech

Abstract:  Argument Technology is that part of the overlap between theories of argumentation and reasoning and those of AI where an engineering focus leads to applications and tools that are deployed. One significant step in the past decade has been the development of the Argument Web — the idea that many of these tools can interact using common infrastructure, with benefits to academic, commercial and public user groups. More recently, there has been a move towards linguistic aspects of argument, with NLP techniques facilitating the development of the field of Argument Mining. Drawing on the academic success and commercial uptake of techniques such as opinion mining and sentiment analysis, argument mining seeks to build on systems which use data mining to summarise *what* people think by explaining also *why* they hold the opinions they do.

Biography:  Chris Reed is Professor of Computer Science and Philosophy at the University of Dundee in Scotland, where he heads the Centre for Argument Technology. Chris has been working at the overlap between argumentation theory and artificial intelligence for over twenty years, has won over £5.6m of funding from RCUK, government and commercial sources and has over 150 peer-reviewed papers in the area including five books.  He has also been instrumental in the development of the Argument Interchange Format, an international standard for computational work in the area; he is spear-heading the major engineering effort behind the Argument Web; and he was a founding editor of the Journal of Argument & Computation.

Seminar: A Changing Landscape: Securing The Internet Of Things (IoT)

Professor Sanjay Jha, Director of the Cybersecurity and Privacy Laboratory (Cyspri) at UNSW.

The first part of this talk will discuss how the community is converging towards the IoT vision having worked in wireless sensor networking and Machine-2-Machine (M2M) communication. This will follow a general discussion of security challenges in IoT.

Finally I will discuss some results from an ongoing projects on security of bodywork devices and IoT. Wireless bodyworn sensing devices are becoming popular for fitness, sports training and personalized healthcare applications. Securing the data generated by these devices is essential if they are to be integrated into the current health infrastructure and employed in medical applications. In this talk, I will discuss a mechanism to secure data provenance and location proof for these devices by exploiting symmetric spatio-temporal characteristics of the wireless link between two communicating parties. Our solution enables both parties to generate closely matching `link’ fingerprints, which uniquely associate a data session with a wireless link such that a third party, at a later date, can verify the links the data was communicated on. These fingerprints are very hard for an eavesdropper to forge, lightweight compared to traditional provenance mechanisms, and allow for interesting security properties such as accountability and non-repudiation. I will present our solution with experiments using bodyworn devices in scenarios approximating actual device deployment. I will also touch upon other research on secure reprogramming of IoT devices over wireless networks.

School Seminar: “The path to Cellular IoT and the promise of 5G” by Frankie Garcia

The School of Computer Science welcomes Frankie Garcia from Keysight Technologies, Edinburgh. Frankie Garcia

Abstract: Over the last two decades we have witnessed an unprecedented growth in the number of Internet-connected devices via the Cloud (storage, compute and intelligent analytics) generally referred to as the Internet of Things (IoT). This includes both machine-to-machine (M2M) and machine-to-person communications on a massive scale. While this growth has been fuelled through standardisation and engineering of short range wireless systems such as Bluetooth, Wi-Fi and Zigbee, cellular technologies promise wide area coverage, ease of deployment and low-cost/low-energy devices capable of operating for many years on a small battery. However, IoT technologies based on existing cellular systems are not optimized to support the huge number of simultaneous connections needed for widespread adoption. To achieve this, radical changes are required in protocol layer design, radio access techniques, and future integrated platforms that can scale and handle millions of devices efficiently. These devices will themselves exhibit a diverse set of requirements with respect to reliability, latency and availability. For these reasons, Cellular IoT has become one of the most important use case drivers in the evolution of future 5G technologies and architectures.

In this talk we will briefly introduce the audience to existing cellular standards and systems to support IoT communications, including their strengths and limitations. We will then cover the path towards more efficient cellular technologies being developed today under 3GPP, focusing heavily on Narrowband IoT (NB-IoT). This will be followed by a short introduction to 5G mobile network evolution needed to reduce signalling overheads and cater for a diversity of IoT use cases. This evolution is driven by tried and tested technologies used for virtualisation such as Software Defined Networking (SDN) and Network Function Virtualisation (NFV). “Slicing”, is a much discussed design principle that that includes logical access, compute, storage and networking for on demand architectures tailored to individual service requirements. Finally, we will present the development of an agile SDR platform targeting experimentation and prototyping of NBIoT systems.

Bio: Educated at Lancaster University, Frankie Garcia is currently Master Scientist with Keysight Technologies in Edinburgh. In addition he is project scientist with Agilent Technologies and over the last two years he has been working on adaptive radio technologies focusing on test and measurements tools and validation tools for the complex interactions that take place between the PHY and MAC layer of such adaptive radios. In particular his focus has been on Mobile WiMAX and presently on LTE.

His experience, based on academic and industrial research labs settings is quite broad raging from distributed systems, protocol engineering, high speed communications, multimedia systems, wireless sensor networks, adaptive radio and QoS.

He is a Visiting Professor at Strathclyde University, Department of Electronic and Electrical Engineering.

Elise van den Hoven : Materialising Memories: a design research programme to study everyday remembering

Abstract


Perhaps the term computer ‘memory’ has led people to believe that human memory has to be perfect and infallible. Many people worry when they realise they forget and some turn to recording and collecting as much as they can, e.g. photos or videos through life logging. Some people assume that by collecting they can avoid forgetting or at least have access to the information anytime later. And that is where they might be wrong. First of all, recordings are not equivalent to memories, and memories ‘can not be stored’. Secondly it has already been shown that people collect too much and organize too little for them to be able to find information later [1]. Thirdly, human memory works best when we forget… a lot.

What I want to talk about is my vision [2] that we can use design research to support human remembering by supporting our memory’s functions [3], which include a directive function (using the past to guide present and future thoughts and behaviours, e.g. solving problems), a self-representative function (creating a sense of self over time) and a social function (developing and nurturing relationships, through sharing of personal experiences). It is important to realise that in order to support these functions there is no need to improve our remembering capabilities, however it could benefit from the right type of support. Since remembering is a reconstructive process, individual memories are subject to change, continuously, and what someone experiences as a memory does not have to be the same as what happened or what other people remember from the experience.

Bits of information from the original experience can be used to stimulate and facilitate the reconstruction process. These so-called memory cues [4], which can be anything: from a photo, a song to a person or a location, are at the core of our research. We use a people-centred approach to study memory cues in everyday life, which informs the design of interactive systems that present these memory cues. Since these cues are often digital, while people prefer material objects [e.g. 5], we combine material and digital in our studies and designs.

Daniel Archambault : Effective Visualisation of Static and Dynamic Graphs

Abstract

Visualising dynamic graphs is important for many application areas.  For social media networks, they can help us understand the interaction and interests of users online.  In biology, they can illustrate the interactions between genes and biological processes.  Understanding and designing effective visualisation methods for dynamic network data is fundamental to these areas as well as many others.  In this talk, we focus on the effective presentation of dynamic networks.  In particular, we summarise recent results on dynamic graph visualisation with respect to animation (presentation of interactive movies of the data), small multiples (presenting the data through several linked windows like a comic book), and drawing stability (the visual stability of the data presentation).  We conclude with some recent work on scalable graph visualisation and in the visualisation of sets and their intersections.

Biography

Daniel Archambault has been working in the field of information visualization for ten years. His work in this area has focused on the development and evaluation of techniques for visualizing dynamic networks and scalable graph visualizations.  His research has been been applied to many areas outside of computer science, including the digital humanities, biology, networking, sociology, and social media analysis.
