SRG Seminar: “Using Metric Space Indexing for Complete and Efficient Record Linkage” by Özgür Akgün

Record linkage is the process of identifying records that refer to the same real-world entities, in situations where entity identifiers are unavailable. Records are linked on the basis of similarity between common attributes, with every pair being classified as a link or non-link depending on their degree of similarity. Record linkage is usually performed in a three-step process: first groups of similar candidate records are identified using indexing, pairs within the same group are then compared in more detail, and finally classified. Even state-of-the-art indexing techniques, such as Locality Sensitive Hashing, have potential drawbacks. They may fail to group together some true matching records with high similarity. Conversely, they may group records with low similarity, leading to high computational overhead. We propose using metric space indexing to perform complete record linkage, which results in a parameter-free record linkage process combining indexing, comparison and classification into a single step delivering complete and efficient record linkage. Our experimental evaluation on real-world datasets from several domains shows that linkage using metric space indexing can yield better quality than current indexing techniques, with similar execution cost, without the need for domain knowledge or trial and error to configure the process.

11:15 Lecture 2
12:15 Break for Lunch (not provided)
14:15 Lecture 3
15:15 Discussion

Lecture 1: Introduction to Scalable Intelligent Systems

Lecture 2: Foundations for Scalable Intelligent Systems

Lecture 3: Implications of Scalable Intelligent Systems

Speaker Bio:

Professor Carl Hewitt is the creator (together with his students and other colleagues) of the Actor Model of computation, which influenced the development of the Scheme programming language and the π calculus, and inspired several other systems and programming languages. The Actor Model is in widespread industrial use including eBay, Microsoft, and Twitter. For his doctoral thesis, he designed Planner, the first programming language based on pattern-invoked procedural plans.

Professor Hewitt’s recent research centers on the area of Inconsistency Robustness, i.e., system performance in the face of continual, pervasive inconsistencies (a shift from the previously dominant paradigms of inconsistency denial and inconsistency elimination, i.e., to sweep inconsistencies under the rug). ActorScript and the Actor Model on which it is based can play an important role in the implementation of more inconsistency-robust information systems. Hewitt is an advocate in the emerging campaign against mandatory installation of backdoors in the Internet of Things.

Hewitt is Board Chair of iRobust™, an international scientific society for the promotion of the field of Inconsistency Robustness. He is also Board Chair of Standard IoT™, an international standards organization for the Internet of Things, which is using the Actor Model to unify and generalize emerging standards for IoT. He has been a Visiting Professor at Stanford University and Keio University and is Emeritus in the EECS department at MIT.

Abstract:

A project to build the technology stack outlined in these lectures can bring Scalable Intelligent Systems to fruition by 2025. Scalable Intelligent Systems have the following characteristics:

  • Interactively acquire information from video, Web pages, hologlasses, online data bases, sensors, articles, human speech and gestures, etc.
  • Real-time integration of massive pervasively inconsistent information
  • Scalability in all important dimensions meaning that there are no hard barriers to continual improvement in the above areas
  • Close human collaboration with hologlasses for secure mobile interaction. Computers alone cannot implement the above capabilities
  • No closed-form algorithmic solution is possible to implement the above capabilities

Technology stack for Scalable Intelligent Systems is outlined below:

  • Experiences Hologlasses: Collaboration, Gestures, Animations, Video
  • Matrix Discourse, Rhetoric, and Narration
  • Citadels No single point of failure
  • Massive Inconsistency Robust Ontology Propositions, Goals, Plans, Descriptions, Statistics, Narratives
  • Actor Services Hardware and Software
  • Actor Many Cores Non-sequential, Every-word-tagged, Faraday cage Crypto, Stacked Carbon Nanotube

For example, pain management could greatly benefit from Scalable Intelligent Systems. Complexities of dealing with pain have led to the current opioid crisis. According to Eric Rodgers, PhD., director of the VA’s Office of Evidence Based Practice:

“The use of opioids has changed tremendously since the 1990s, when we first started formulating a plan for guidelines. The concept then was that opioid therapy was an underused strategy for helping our patients and we were trying to get our providers to use this type of therapy more. But as time went on, we became more aware of the harms of opioid therapy and the development of pill mills. The problems got worse.

It’s now become routine for providers to check the state databases to see if there’s multi-sourcing — getting prescriptions from other providers. Providers are also now supposed to use urine drug screenings and, if there are unusual results, to do a confirmation. [For every death from an opioid overdose] there are 10 people who have a problem with opioid use disorder or addiction. And for every addicted person, we have another 10 who are misusing their medication.”

Pain management requires much more than just prescribing opioids, which are often critical for short-term and less often longer-term use.

SRG Seminar: “Efficient Cross-architecture Hardware Virtualisation” by Tom Spink

Virtualisation is a powerful tool used for the isolation, partitioning, and sharing of physical computing resources. Employed heavily in data centres, becoming increasingly popular in industrial settings, and used by home-users for running alternative operating systems, hardware virtualisation has seen a lot of attention from hardware and software developers over the last ten?fifteen years.

From the hardware side, this takes the form of so-called hardware assisted virtualisation, and appears in technologies such as Intel-VT, AMD-V and ARM Virtualization Extensions. However, most forms of hardware virtualisation are typically same-architecture virtualisation, where virtual versions of the host physical machine are created, providing very fast isolated instances of the physical machine, in which entire operating systems can be booted. But, there is a distinct lack of hardware support for cross-architecture virtualisation, where the guest machine architecture is different to the host.

I will talk about my research in this area, and describe the cross-architecture virtualisation hypervisor Captive that can boot unmodified guest operating systems, compiled for one architecture in the virtual machine of another.

I will talk about the challenges of full system simulation (such as memory, instruction, and device emulation), our approaches to this, and how we can efficiently map guest behaviour to host behaviour.

Finally, I will discuss our plans for open-sourcing the hypervisor, the work we are currently doing and what future work we have planned.

School Seminar – Professor Anirudha Joshi: The story of Swarachakra – Cracking the puzzle of text input in Indian languages

Title: The story of Swarachakra – Cracking the puzzle of text input in Indian languages

Abstract: There was a time when text input in Indian languages was called a ‘puzzle’. People found it so difficult that became a barrier that prevented them from using most other technology products, from doing common tasks such as searching the web or saving a contact. As a result, Indians typed very little in their own languages. The Roman script (in which we write English) is an Alphabet. In contrast, a large majority of Indian scripts are Abugidas – a different type of scripts. In our lab, we were convinced that we need different solutions – what works for Alphabets may not work for Abugidas. Over the years we explored several designs. Our early solutions were for desktop computers. Later we developed concepts for the feature phones. We tried several creative ideas and made prototypes. We got interesting results in the lab. We published papers and case studies. But beyond that, we could not reach out and make a difference to the end-users. Then smartphones arrived, and quickly became popular. It became relatively easier to develop and deploy keyboards. Again, we tried several ideas. One solution stood out in comparison with others. We called it “Swarachakra”. Today, Swarachakra is available for 12 Indian languages and has been downloaded by about 4 million users. What was the problem, and how was it solved? And what challenges remain? Come to the talk to find out.

Pascal Bruegger: Resident Monitoring System

Abstract:

The situation in hospitals, nursing homes and homes for patients suffering from mental illnesses is increasingly challenging. The medical staff and special educators are often responsible for a large (and growing) number of residents, for which there is only a very limited time for one-to-one care. The risk of not being able to respond promptly to problems increases with the number of residents per medical staff. Moreover, elderly people find challenging giving and up independence when moving into a nursing home. Overnight, they find themselves in a place where care activities are structured, and at fixed times, with little freedom. However, many of these people either need regular medical care or are unable to live independently. The risk of injuries, falls, loss of consciousness or simply not being able to manage their health (e.g. take medication) leads to the decision to place the person in a socio-medical environment.

To be able to monitor residents in a nonintrusive manner would provide a certain degree of independence, safety and well-being for the residents and also relieve some of the pressure on nurses and educators. The ideal monitoring system should in fact be an ecosystem that includes sensors that can localise and detect resident’s activities and collect physiological data, a way of sending regular updates about the situation of the residents they take care of medical staff and a central monitoring system for both residents and medical staff and a logic to decide the most appropriate available person to intervene in case of problems with a resident. We propose an exploration of solutions that blend new technologies with a respect for human relationships in the context of a nursing home. This is to be achieved through an intelligent environment that monitors a resident’s general well-being unobstrusively, meaning both the physiological state, the activity and the location of the person.

School Seminar – Professor Patrick Olivier – Digital Civics: Infrastructuring Participatory Citizenship

Title:  Digital Civics: Infrastructuring Participatory Citizenship

Abstract:  Firstly, this is not technical talk, its a talk about a research initiative in “Digital Civics” that Open Lab is undertaking primarily with partners in the North East of England, but also nationally and internationally. Digital Civics proposes the use of digital technologies in the provision of relational models of public services, that is, models that take as a starting point the potential of digital technologies to support citizen-focused sharing of knowledge, experience and resources. By framing government as more than simply the provider of uniform and mechanistic services, digital civics aims to leverage technology to foster environments in which local agents (e.g. charities, local businesses, citizens) are able to solve problems together. Digital Civics research is inherently cross-disciplinary, action-oriented and place-based, and this requires us (as academic researchers) to configure ourselves differently to the communities with whom we conduct our research. In this talk I will be describing examples of our digital civics research, from applications in community engagement and education to public health and social justice, as well as the trajectory and pragmatics of the overall endeavour.

Speaker biography:  Patrick Olivier is Professor of Human-Computer Interaction in the School of Computing, Newcastle University, UK. He founded and leads Open Lab, Newcastle University’s centre for cross-disciplinary research in digital technologies. His research interests span interaction design, social computing and ubiquitous computing, particularly in public service and civic application contexts (education, public health and social justice). He is director of the EPSRC Centre for Doctoral Training in Digital Civics (55 cross-disciplinary PhD students) and the EPSRC Digital Economy Research Centre (a multidisciplinary five-year project involving 25 postdocs).
