Among the other responsibilities of the voting committee, Isabel did proactive work giving several talks to groups concerned with Software and Quality Improvements in the USA, Portugal and Spain, and her last talk at the Software Excellence Alliance (USA) can be watched here.

DEI Talks | “Clustering Healthcare Data” by Prof. Pasi Fränti

Posted on

Pasi Fränti received his MSc and PhD degrees from the University of Turku, in 1991 and 1994 in Science. Since 2000, he has been a professor of Computer Science at the University of Eastern Finland. He has published in 99 journals and 175 peer review conference papers. Pasi Fränti is the head of the Machine Learning research group. His current research interests include clustering algorithms, location-based services, machine learning, web and text mining, and optimization of health care services. He has supervised 30 PhD graduates and is currently supervising nine more.

 “Clustering Healthcare Data” will be presented November 7, at 11:00, in room I125 – participation is  free, all are welcome.

 Abstract: Clustering can a powerful tool in analyzing healthcare data. We show how clustering based on k-means and its variants can be used to extract new insight from various data with the aim to better optimize the health care system. We first show that simple variants of k-means and random swap algorithms can provide highly accurate clustering results. We demonstrate how k-means can be applied to categorical data, sets, and graphs. We model health care records of individual patients as a set of diagnoses. These can be used to cluster patients, and also create co-occurence graph of diagnoses depending on how often the same pair of diseases are diagnosed in the record of the same patient. Taking into account the order of the diagnoses, we can construct a predictor for the likely forthcoming diseases. We also provide a clustering algorithm to optimize the location of health care systems based on patient locations. As a case study, we consider coronary heart disease patients and analyze in what way the optimization of the locations can affect the expected time to reach the hospital within the given time. All the results can provide additional statistical information to healthcare planners and also medical doctors at the operational level to guide their efforts to provide better healthcare services.

DEI Talks | “Tools and methods for the understanding of road users behaviours” by Prof. Stéphane Espié and “Driving-Pattern Identification and Event Detection Based on an Unsupervised Learning Framework: Case of a Motorcycle-Riding Simulator” by Prof. Abderrahmane Boubezoul

Posted on

Within the framework of the European University Alliance for Global Health (EUGLOH), we are glad to host the visit of Stéphane Espié and Abderrahmane Boubezoul, visiting DEI during this week (17-21).

Our guests will deliver two seminars on Friday, October 21, at 9:00, in Room B 009. You are all invited!

 “Tools and methods for the understanding of road users behaviours”

By the Author:

“To be efficient and accepted, road safety counter-measures need to be defined thanks to scientific studies. The question is not only to imagine an optimal solution in the absolute, but to understand the real practices and, based on this knowledge, to design the measures (sensitivity campaigns, changes in Highway Code, changes in initial training curriculum or licence tests, infrastructure (re)design, vehicles homologations, etc.).

In our talk we will describe the tools and methods we promote and refined for decades to improve road safety, and their use in research projects. Our approach is systemic and is based on three pillars: instrumentation of vehicles for in-depth naturalistic studies, traffic modelling and simulation using a multi-agents system, and design of driving simulators to study driving behaviours. We will illustrate our approach using research projects we have conducted over these last years.

Stéphane ESPIÉ is a research director at the Gustave Eiffel University. He holds an Accreditation to Direct Research in Computer Science (HdR, Pierre et Marie Curie University, 2004). His main research areas are behavioural traffic simulation (MAS based), and the design of tools to study road user behaviours (driving/riding simulators and instrumented vehicles). He currently conducts his research in SATIE laboratory (Paris Saclay university) where he leads the MOSS (Methods and Tools for Signals and Systems) research group.

“Driving-Pattern Identification and Event Detection Based on an Un-supervised Learning Framework: Case of a Motorcycle-Riding Simulator”

By the Author:

“Analysis of human driving behavior aims to inspect drivers’ behavior in the real-world and in a virtual environment. The study of driving behaviors can be conducted in naturalistic situations or controlled experiments. Analyzing driving behaviors based on the data collected in naturalistic driving experiments or controlled experiments in the real-world or in a virtual environment is beneficial to fill in many of the knowledge gaps about driving behaviors and risk factors. I will present a multi-step framework for analyzing driving behavior on macroscopic and microscopic scales. The core step of this framework is based on unsupervised machine learning algorithms applied to driving-pattern identification and the detection of critical driving events using anomaly-detection algorithms. The detected events are interpreted and described by computing their feature importance using graphs centrality measures. This provides new insight into driving behavior by identifying the motives behind the driver’s actions.

Abderrahmane Boubezoul received his Ph.D. in Computer Science and Mathematics from University Paul Cézanne (Aix-Marseille III), France in 2008 and his Master’s degree in Virtual Reality and Complex Systems from Evry Val d’Essone University, France. Since 2008, he is a researcher at Gustave Eiffel University. His current work is about statistical signal processing and machine learning applied to road transport systems. He currently conducts his research in SATIE laboratory (Paris Saclay university) MOSS (Methods and Tools for Signals and Systems) research group.

Creativity Talks 08 – “A Theoretical Computer Science Perspective on Consciousness: Insights from the Conscious Turing Machine” by Lenore and Manuel Blum

Posted on

The eighth session of the Creativity Talks will have as keynote speakers the distinguished Professors at Carnegie Mellon School of Computer Science Lenore Blum and Manuel Blum.

Lenore and Manuel Blum, recipients of the PAESMEM and Turing awards, respectively, will present at FEUP “A Theoretical Computer Science Perspective on Consciousness: Insights from the Conscious Turing Machine” on September 29, at 18:00, in Room B032, and also streamed online via Youtube.

“We are Theoretical Computer Scientists. Theoretical Computer Science is a subarea of Mathematics that has tools, we claim, ideally suited to understanding consciousness. We have applied these tools to produce a model of consciousness that we call the Conscious Turing Machine (CTM). Our model gives insight into what goes on in our head to cause us to feel conscious. It also suggests how machines may be constructed to be conscious.

A Turing Machine (TM) is a very simple device defined mathematically by Alan Turing. There is no way that anyone would or should consider a TM to be conscious. However, with the advent of fMRI in 1990, advances in Neuroscience, and the Global Neuronal Workspace Models of Baars, Changeaux, and Dehaene, we have defined a variant of TM, the CTM, that we argue gives insight into consciousness.

Lenore will present and explain our model of consciousness, the CTM. Manuel will discuss how and why the CTM experiences feelings of consciousness”, shares Prof. Blum.

To attend the lecture at the Faculty of Engineering of the University of Porto, please register HERE! Participation at the event is free of charge, but registration is compulsory. Online participation does not require any registration.

Lenore Blum has been passionate about mathematics since she was 10. She attributes that to having dropped out of school when she was 9 to wander the world, then hit the ground running when she returned and became fascinated with the Euclidean Algorithm. Her interests turned to non-standard models of mathematics, and of computation. As a graduate student at MIT, she showed how to use saturated model theory to get new results in differential algebra. Later, with Mike Shub and Steve Smale, she developed a foundational theory for computing and complexity over continuous domains such as the real or complex numbers. The theory generalizes the Turing-based theory (for discrete domains) and has been fundamental for computational mathematics. Lenore is internationally known for her work in increasing the participation of girls and women in STEM and is proud that CMU has gender parity in its undergraduate CS program. Lenore is currently president of the Association for Mathematical Consciousness Science. Lenore Blum: lblum@cs.cmu.edu

Manuel Blum has been motivated to understand the mind/body problem since he was in second grade when his teacher told his mom she should not expect him to get past high school. As an undergrad at MIT, he spent a year studying Freud and then apprenticed himself to the great anti-Freud neurophysiologist Warren S. McCulloch, who became his intellectual mentor. When he told Warren (McCulloch) and Walter (Pitts) that he wanted to study consciousness, he was told in no uncertain terms that he was verboten to do so – and why. As a graduate student, he asked and got Marvin Minsky to be his thesis advisor. Manuel is one of the founders of complexity theory, a Turing Award winner, and has mentored many in the field who have chartered new directions ranging from computational learning, cryptography, zero knowledge, interactive proofs, proof checkers, and human computation.

Abstract

Generally speaking, a large-scale socio-technical system is formed up of individual entities that are distributed along with the system’s space and act asynchronously in their decision making processes. Each of the individuals bears its own goals and tends to behave rather “selfishly” and “greedily” to maximise self-welfare utilities. However, this characteristic will generally affect negatively the global efficiency and the designed (expected) emergent behavior of the system. Indeed, private road transport imposes negative externalities on society, such as road capacity restrictions, accidents, congestion, etc. An efficient mobility model must take into account the real costs of transport, and its regulatory framework will need to produce the conditions for people to make sustainable transport choices. Economic theories offer two types of instruments for addressing the problem of transport externalities: command-and-control and incentive-based policies.

Command-and-control policies are government regulations which force users to change their behavior. In that sense, recent approaches to optimise the traffic network throughput and reduce traffic congestion basically rely on “road pricing”. However, this approach ends up penalising the user and creating social inequalities as it imposes a tax to be paid. Only those who are insensitive to the price will benefit. Also, a population may not be responsive to the defined penalties, and thus, the regulation may not be efficient.

On the other hand, an approach that has gained the community’s attention is based on the implementation and design of incentive schemes in public policy. Incentives are seen as those external measures that try to motivate a behavior change towards the objective of the system. It appears to be a “fairer” vision, as it does not discriminate the user but rather tries to bring the society into equilibrium.

The domain area on which this PhD thesis is focused concerns open and competitive multiagent systems, such as the Intelligent Transportation Systems (ITS) and the electricity markets. This thesis intends to address the issue of whether or not incentive-centred designs can favour the emergence of social-aware behavior in agents that have selfish tendencies for a (global) optimal evolution of a socio-technical system. Traditional transport planning tools using the four-step model combined with standard economic appraisal methods are not able to provide such analysis. Instead, a multi-agent system (MAS) social simulations can be used as it is argued in the literature of complex systems.

Keywords: Multi-Agent Systems, Incentive Mechanisms, Resource Markets, Policy Evaluation, Traffic Simulation.

Abstract

The aim of this thesis is to connect people with underwater environments while creating awareness for the problem of anthropogenic noise pollution through artistic creation. This dissertation addresses the lack of information on underwater noise discourse, especially on the vibrational aspect of underwater sound. By asking how to convey the experience of underwater soundscapes and their human disruption, it proposes two major directions that inform and complement each other. First, several underwater soundscape recordings were realised. They provide an understanding of the ambience of places and allow attunement with the natural world. Second, six practice-based research artworks based on the soundscape recordings and methods from acoustic ecology and ecoacoustics, focusing on anthropogenic sounds aimed at improving inclusion with nature while creating awareness of the noise pollution problem. The revised strategies and concepts included place attachment, emotional affinity, nature-connectedness and ecology of æffect. These artworks provide the setting for challenging audiences to bond with underwater environments by listening to their soundscapes while revealing a particular aspect of underwater sound. Moreover, they explore creative strategies for developing sonic experiences with the introduction, experience and performance of underwater sounds in artistic creation. Additionally, the artworks introduce and approach a natural phenomenon related to underwater sound (Luciferina – bioluminescence; SINØ III – cymatics; #switchoffandlisten – noise awareness campaign; DIS_turbation – bioturbation; Munda – cavitation; 2182kHz – auditory masking). The insights from the artistic experiences proved critical to continue producing innovative contributions and to create knowledge while influencing the communities. The significance of this study is that it informs the theoretical understanding of noise pollution impacts on aquatic fauna and underwater acoustics by introducing a focus on the vibrational aspect of underwater sound: particle motion. In addition, it informs the empirical understanding of the practice-based research on developing the proposed artworks. The novelty lies in addressing biological phenomena as a creative resource to intervene in underwater noise dialogue, reveal hidden qualities of vibroscape ecology (such as particle motion) and translate them in a more grasping way through the artistic artworks. As underwater soundscapes are increasingly a topic of concern globally, they become crucial to fostering an emotional affinity between people and natural environments, promoting inclusion with nature.

Keywords: ecological sound art, acoustic ecology, underwater soundscapes, anthropogenic noise, vibroscape ecology, nature-connectedness, ecology of æffect.
