Artificial Intelligence in Oncology

Dr. Nikolay Burlutskiy | 28/04/2021 @ 1600 | Virtual | A SET Digital Seminar

 

Abstract In recent years, Artificial intelligence (AI) has attracted many researchers to improve healthcare. Advances in machine learning and especially in deep learning along with availability of large medical datasets has driven development of innovative applications to improve the patient journey. Such applications include disease diagnosis, prognosis, treatment and clinical workflow optimisation. Since the world’s population is ageing rapidly and the incidence of cancer rises dramatically at an older age, there is a specific interest in the applications of AI to oncology. In this talk, we will discuss the role of AI in oncology, digital pathology, radiology, drug discovery. We will look at current challenges and concerns around AI such as generalisability, interpretability, potential bias, and ethical considerations.

Bio Dr Nikolay Burlutskiy is an AI Scientist at Early Oncology R&D, AstraZeneca, UK. Nikolay’s interest is in applying AI methods to improve oncology healthcare and novel drug discovery. Nikolay has a MSc in Computer Science from Seoul National University and acquired his PhD from the University of Brighton. Prior to AstraZeneca, he worked as a research scientist at Context Vision in Stockholm, Sweden and as an R&D software engineer at Samsung Electronics in Suwon, South Korea. He co-authored over 20 peer-reviewed publications including several US patents on AI applications.

Listening to social media through Natural Language Processing and Geo Intelligence

Stefano Vacca | 12/05/2021 @ 1600 | Virtual | A BSEL Seminar

Abstract Social Data Intelligence is a particular form of data analysis that is focused on social media data. On the web and especially on social networks, vast amounts of different kinds of data are produced. People use Twitter, Instagram, Tik Tok, Fortnight, Twitch, and write down their impressions, opinions, and feelings about political events, social phenomenon, and famous people. This seminar aims to show, through practical use cases, how it is possible to use innovative data mining techniques to extract hidden information from social media to measure a specific phenomenon to help management make decisions around specific trends (and discover new opportunities) or how to use these techniques for research purposes.

Bio Stefano Vacca is a Data Scientist at Alkemy S.p.A (Milan, Italy) since 2018. He holds a bachelor’s degree in Economics and Finance, defending a thesis focused on Smart Cities’ European legislation. In 2020 he obtained a master’s degree in Data Science, Business Analytics and Innovation at the University of Cagliari (Italy), bringing a thesis entitled “Hawkes processes for the identification of premonitory events in the cryptocurrency market”. In 2019 he worked on a project for Enlightenment.ai company (Lisbon, Portugal) to construct computer vision algorithms to recognise digits starting from counter meter images. Stefano regularly gives seminars for both academia and industry and he has published several research papers in the field of data mining for cryptocurrencies.

Verifying GPU programs

Dr Tiago Cogumbeiro | 10/03/2021 @ 1600 | Virtual | Part of the SET Digital Series

 

Abstract GPUs offer parallelism as a commodity, but they are difficult to program correctly. Static analyzers that guarantee data-race freedom (DRF) are essential to help programmers establish the correctness of their programs (kernels). However, existing approaches produce too many false alarms and struggle to handle larger programs. To address these limitations we formalize a novel compositional analysis for DRF, based on access memory protocols. These protocols are behavioural types that codify the way threads interact over shared memory. Our work includes fully mechanized proofs of our theoretical results, the first mechanized proofs in the field of DRF analysis for GPU kernels. Our theory is implemented in Faial, a tool that outperforms the state-of-the-art. Notably, it can correctly verify at least 1.41× more real-world kernels, and it exhibits a linear growth, while others grow exponentially.

Bio Tiago is an assistant professor at UMass Boston. Tiago’s research helps programmers write software with fewer bugs. Tiago develops tools that localize errors, proves the correctness of algorithms, and mines how we write code to identify anomalies.

Agile Software Architecture Practices

Dr Eduardo Guerra | 03/03/2021 @ 1600 | Virtual | A BSEL Seminar

 

Abstract Working with software architecture in agile projects is hard: you need to start as fast as you can, but also need to have a sustainable base architecture that you will be able to evolve through the project. This talk presents a set of patterns identified on real projects, that focus on practices for creating and evolving a software architecture in the context of an agile project. These practices provide a set of tools to the team that can allow them to define an “enough” architecture at the beginning of the project and manage the state and its evolution during the project iterations.

Bio Eduardo Guerra is a Researcher at the Free University of Bozen-Bolzano (UniBZ, Italy) since 2020. He received the Master Degree in Electronic and Computer Engineering from the Instituto Tecnológico de Aeronáutica (ITA, Brazil) in 2005 defending a thesis on test code refactoring. In 2010 he received the PhD degree in Electronic and Computer Engineering from the Instituto Tecnológico de Aeronáutica (ITA, Brazil) in 2010 defending a thesis on metadata-based frameworks design. From 2007 to 2012, as an officer from the Brazilian Air Force, worked as a teacher for undergraduate and graduate courses in the Instituto Tecnológico de Aeronáutica (ITA, Brazil). From 2013 to 2019, worked as a researcher in the Associate Laboratory of Applied Mathematics and Computation (LABAC) in the field of software engineering in the National Institute for Space Research (INPE, Brazil). Eduardo Guerra’s research’s focus can be defined as “find better ways to develop software”, which can include programming approaches, architecture solutions, and development processes.

The Digital Transformation Journey: Contrasting Case Studies

Jawad Keshtgar – BMI Healthcare | 17/02/2021 @ 1600 | Virtual | Part of the SET Digital Series

 

Abstract Today people, organisation, and information technology are expected to operate as part of a seamless whole – both within and across organisational boundaries. This places stringent new demands on the knowledge, skills and technologies required to develop and manage such complex inter-related systems – in an ever increasing digital society.

As a result, Digital Transformation is fast becoming central to society particularly due to the rapid rate of digital convergence – especially in business. As society and technology develop in parallel, the most important skills for organisations is the ability to both understand and manage these complex interdependencies between I.T. and business in a dynamic globalised environment.

Bio A former Brunel University graduate in Information Systems, currently working at BMI Healthcare as the Lead Business and Change Analyst. Over the past eight years following graduation, my experiences have led me to work for the UK’s largest employer (NHS), be part of Europe’s largest IT project with Allianz and most recently work for the UK’s largest private healthcare organisation. My journey began at Brunel’s Science Park, with the start-up company ‘BTO Research’. My involvement with BTO, allowed me to valorise applied research techniques from academia to organisations; it is this relationship that motivates my personal mission to help foster closer relationship between Industry Leaders and Universities.

Quantum Computing Concepts: Towards a new Programming Paradigm

Dr Manuel A. Serrano | 18/11/2020 @ 1500 | Virtual | Part of the SET Digital Series

 

Abstract At the dawn of the last century, the basis of “quantum mechanics” was established by many exceptional scientists, such as Einstein, Schrödinger, Heisenberg or Pauli. This theory describes the behaviour of nature at subatomic levels (photons, electrons, etc). In 1982, Nobel laureate Richard Feynman asked: “What kind of computer are we going to use to simulate physics?” This is how the idea for quantum computing was born. Quantum computers attempt to use various “counterintuitive” principles such as superposition (objects can be in different states at the same time) and entanglement (objects can be deeply connected without any direct physical interaction) in the effort to provide faster computing speed. We can already use quantum computers and take advantage of their huge computation capacity to solve problems which are considered very difficult for today’s and tomorrow’s “classic” computers. This new computing paradigm has a great deal of direct applications, and many other potential ones. For example, applications include economics, chemistry, medicine, logistics, energy and agriculture. All the applications mentioned will not be accomplished with quantum computers alone; these applications need quantum software. In this seminar the fundamental quantum concepts are exposed, with special emphasis on those that must be known by those who wish to begin the approach to the world of Quantum Software Engineering and Programming. This seminar offers an interesting “tour” of Quantum Concepts such as Quantum Mechanics, Qubits, Hilbert Space and Quantum Circuits.

Human factors in Software Engineering

Lucas Gren | 10/10/2019 @ 1500 | BSEL Lab | A BSEL Seminar

There has been an increase in the interest of human factors in SE in recent years. Most new research fields that start to look at psychological aspects, start with individual psychology since people are different and that makes intuitive sense to everyone. While these are important aspects, the social psychology research field also highlights the importance of a profound understanding of the complex interplay between social context and affect, since affect influence cannot be explained in isolation. In this talk, I would like to introduce under which judgemental circumstances people are affected by affect and suggest how to add social context to studies on affect. I also reflect on why the individual focus in human factors of SE is so rigid and attribute much of it to an over-belief in the benefits of digitalization (e.g. biometrics). Another part of the problem, the way I see it, is that these new digital solutions aim at maximizing happy feelings while social psychology studies suggest that is not how to maximize effectiveness or long-term high motivation in employees.

Software architecture to Everything

Nour Ali | 12/06/2019 @ 1400 | WLFB207/208 | A BSEL Seminar

Software architecture is the structure or structures of a software system. A software architecture of a system is, usually, represented by a model that graphically shows software elements and their interactions. Explicit software architectural models are used as critical knowledge to ensure the quality, understanding and evolution of systems.
In this talk, I will motivate you to use software architecture as a tool to manage software. I will demonstrate how we can combine software architecture with formal methods, static/dynamic analysis, optimization techniques and others. I will first start by showing the importance of an architectural model during the evolution and maintenance of a legacy system. I will then focus on architectural models of adaptable, distributed and mobile systems. I will also give you an overview of the latest projects I am working on such as the recovery of microservice architectures, the support of smart mobile and Internet of Things applications and the self-adaption to resource constraint environments.

The Relevance of Application Domains in Empirical Findings

Andrea Capiluppi | 08/05/2019 @ 1400 | WLFB207/208 | A BSEL Seminar

Research on empirical software engineering has increasingly used data from online repositories or collective efforts. The latest trends for researchers is to gather as much data as possible to (i) prevent bias in the representation of a small sample, (ii) work with a sample as close as the population itself, and (iii) showcase the performance of existing or new tools in treating vast amount of data. The effects of harvesting enormous amounts of data have been only marginally considered so far: data could be corrupted; repositories could be forked; and developer identities could be duplicated. In this paper we posit that there is a fundamental flaw in harvesting large amounts of data, and when generalising the conclusions: the application domain, or context, of the analysed systems must be the primary factor for the cluster sampling of FOSS projects. In this talk we analyse a sample of software systems, and using an existing approach based on Latent Dirichlet Allocation (LDA), we derive their application domains. We extract a suite structural OO metrics from each project, and cluster projects by domains: we show that most of the chosen metrics come from different populations, and are based on the application domains.

A Brief History of Types

Rumyana Neykova | 06/03/2019 @ 1400 | WLFB207/208 | A BSEL Seminar

Types are one of computing’s most successful concepts, they exist from the oldest to the newest programming languages. Types act as the fundamental unit of compositionality, and play important role in all aspects of software, from design to optimisation. Unfortunately, types are probably the last thing that comes to your mind when you think about distributed systems. In this talk, I will change this misconception. I will (hopefully) convince you that types can be used to understand, test, specify and verify distributed systems. In particular, I will give you a crash course on session types, which were born as types for distributed processes. We will discuss the history of session type, the fundamental meaning of communication, and how to develop distributed systems that we can trust.

Software Engineering? Are you kidding me?

Giuseppe Destefanis | 13/02/2019 @ 1400 | WLFB207/208 | A BSEL Seminar

Software development is a complex human process which has, as a final goal, the creation of a complete working application. Software Engineering encompasses all the activities related to software development from conceiving to maintaining the product. Calling software a product, however, highlights all the difficulties of the subject, with “immateriality” being the first one. Engineering is defined as “the branch of science and technology concerned with the design, building, and use of engines, machines, and structures.” (Oxford Dictionary). Is the combination of the two words “Software” and “Engineering” an oxymoron?
