DEI Talks | “Computational Inaesthetics: Expanding the Boundaries of Artistic Research and Computational Aesthetics” por Martinus Suijkerbuijk

“Computational Inaesthetics: Expanding the Boundaries of Artistic Research and Computational Aesthetics” será apresentada sexta feira, 24 de março, às 14:30, sala I-105, com a moderação do Prof. António Coelho, docente do DEI.

Pelo autor:

“The increasing use of digital technologies in artistic practice, coupled with the recent emergence of AI, has led to a growing intersection and mutual influence between two related fields: artistic research and computational aesthetics. Artistic research involves using artistic practices to generate new insights and understandings about the world and reflect critically on the process of creating art. In contrast, computational aesthetics involves the theory, practice, and implementation of aesthetics within the domain of computing, and in its most formal version relies on mathematical and computational methods to generate and evaluate art.

However, there has been criticism of computational aesthetics for failing to account for the subjective and non-algorithmic nature of aesthetic experience. Nonetheless, this presentation proposes a practical framework that seeks to resolve this critique by highlighting an expanded view of computational aesthetics, which the presenter terms Computational Inaesthetics.

Through the discussion of basic concepts and principles of artistic research and computational aesthetics, and through the analysis of a selection of artworks by the presenter, the presentation explores the ways in which these fields can inform and enhance each other. Furthermore, the presentation provides an overview of the artistic contents and theoretical underpinnings of the presenter’s artistic research PhD project.

Overall, this presentation showcases the exciting potential of bringing together artistic research and computational aesthetics to expand our understanding of aesthetics, art, creativity, and the role of technology and computation in society.”

Martinus Suijkerbuijk is an artist, designer and engineer that currently is working towards completing his artistic research PhD at the Trondheim Academy of Fine Art, Norway. His artistic research is focused on the concept of Computational Aesthetics, which he explores through the use of AI empowered Artificial Aesthetic Agents (AAA) in virtual environments. His diverse background has enabled him to present his research and work at cultural institutions such as ZKM and MetaMorf, as well as technology conferences like CHI 2018 and Philips Trend Event.

Invited Talks | “Driving Simulators for the Study of Road Users’ Behaviour” pelo Prof. Stéphane Espié

“Driving Simulators for the Study of Road Users’ Behaviour” será apresentado terça-feira, 7 de março, às 17:15, na sala B012.

“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 behaviors. 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 behavioral traffic simulation (MAS based), and the design of tools to study road user behaviors (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.

AutoML and Meta-learning for Neural Network Robustness Verification” será apresentada dia 25 de janeiro, às 14:45, na sala B006 – a entrada é livre, são todos bem vindos.

Abstract: Artificial intelligence is being increasingly integrated in modern society, with applications ranging from self-driving cars to medicine development. However, artificial intelligence models (in particular neural networks) have been notoriously known for being susceptible for various forms of attacks, including adversarial attacks. In a bid to make these models more trustworthy, the field of neural network robustness verification aims to determine to which degree a given network is susceptible to such an attack. This is a very time consuming task, that can greatly benefit from the various advances that the Automated Machine Learning and meta-learning community have made.

In this talk, it will be explained the basis of automated machine learning and meta-learning, and the speaker will talk about their research on applying this to robustness verification. He will also explain how the community can further engage in this endevour towards trustworthy artificial intelligence.

 “Clustering Healthcare Data” será apresentada no dia 7 de novembro, às 11:00, na sala I125 – a entrada é livre, são todos bem vindos.

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 | ”Mergeable Nervous System for Robot Swarms” por Marco Dorigo

Marco Dorigo é o proponente do conhecido algoritmo de otimização meta-heurístico “Ant Colony Optimization” e um dos principais investigadores na área de “swarm robotics”, que permite a grupos de agentes/robôs individualmente muito simples obter inteligência de grupo que permita coordenar grandes grupos de agentes/robôs autónomos sem depender de qualquer infraestrutura externa ou de qualquer forma de controlo centralizado. Esta abordagem é bastante promissora para a realização de tarefas demasiado difíceis ou perigosas para os seres humanos utilizando conjuntos de agentes/robôs muito simples e baratos.

”Mergeable Nervous System for Robot Swarms” será apresentado dia 29 de junho, na I-105, às 16:00.

Abstract:

Typically, robot swarms coordinate through self-organization. With the proposal of the mergeable nervous system concept, we study how self-organisation can be made more powerful as a tool to coordinate the activities of a robot swarm by injecting some components of hierarchical control. In the presentation, I will give a brief overview of the mergeable nervous systems concept and then illustrate the first steps we have made in implementing it in a heterogeneous swarm composed of drones and ground robots.

“A Geographies of born-digital translation: TRANS.MISSION[A.DIALOGUE] as a case study” será apresentada dia 27 de junho, na I-105, às 15:00.

Abstract:

 This presentation addresses the challenges of linguistic, geographical, and cultural translation through the specific case of J.R. Carpenter’s born-digital work TRANS.MISSION[A.DIALOGUE] and its translation from English into Finnish. I will consider how the challenges of linguistic translation from a European to a non-European language are further complicated by the requirements of code, as well as the translation of sociocultural context. Through its focus on technology, mobility, and migration, I suggest, Carpenter’s work invites us to consider the entangled connections between infrastructural geographies and the language of communications technology.

 Junte-se a nós no dia 6 de junho, às 14:00, na sala I-105 da FEUP, para a apresentação de “Digital Culture and Cultural User experience”.

 Abstract:

The immense interest in academia and the cultural industry has been to augment users’ participation during their interaction with cultural artefacts by making them an actor in their own cultural experience. Cultural User eXperience (CUX) has gained momentum in recent years, and a factor that affects CUX is the cultural background and profile of the individual user. Users have their own cultural characteristics and preferences, they learn and interact differently with a particular artefact, and finally, they obtain a unique cultural experience.

CUX is an essential consideration that should be acknowledged and implemented when initiating the Cultural Heritage (CH) domain. It is beyond the usability of a cultural product or system. It includes both pragmatic and hedonic user factors that could influence a user’s positive experience when interacting with the system or product, leading to the effectiveness of CH activities. The diversity of visitors to cultural spaces is one of their unique attributes and is becoming a significant challenge for these venues to meet their visitors’ needs. How can they address the variety of interests and needs of all their visitors? Therefore, it is necessary to know visitors’ expectations when visiting cultural spaces.

The cultural tourists of today (at least in developed countries) travel more than the tourists of the past, and it is possible that the tourists of tomorrow will travel even more often, increasing the level of cultural user experience. Therefore, travelling, which was considered a ”luxury good” in the past, is an integral part of people’s lives nowadays. Also, tourists do not leave their previous experiences, motivations, preconceptions, and attitudes behind when they travel, the same way they leave their coats in the cloakroom upon entering a museum. Furthermore, the effects of a journey are not limited to the time spent at the destination. Tourists connect information and construct meaning before travelling to a place and continue to do so months or even years after their journey.

It is indisputable that cultural tourism destinations require detailed categorization of their visitors and their underlying motivations since not every person is motivated by the exact reasons for learning, experimenting, or self-exploring. Because of this assumption that cultural tourists are not alike, most of the literature in cultural tourism follows a clustering approach, emphasizing determining the typology of the cultural tourists.

Amongst the abundance of tools available for interaction design, user typologies have been claimed to be “the most effective and fundamental”. By creating a concrete image of the user, designers gain insight into the elements a User Interface (UI) should have and how the user is likely to respond to those elements.

Furthermore, during the past years, cultural interactive experiences are produced in an increased pace to bring back the lost fiction, as well as the functional and ritual nature of the cultural objects. To date, there are various technologies available in cultural environments to support cultural exhibitions directly or indirectly (augmented reality, digital storytelling, serious games, linked open data, context awareness), and every technology used makes an impact on the exhibition or the visitors.

Licenciado em Informática em 2006 pelo Instituto Superior de Educação, obteve o grau de Mestre em Engenharia Electrónica e Telecomunicações pela Universidade de Aveiro em 2010. Possui o certificado de Estudos Avançados e é Doutor em Ciência e Tecnologia pela UaB e UTAD desde 2021. Tem como áreas de interesse a Cloud computing e os seus paradigmas. Autor de vários artigos focando ‘Job Scheduling in Fog Paradigm’.

Junte-se a nós no dia 11 de maio, às 14:30, na sala I-105 da FEUP, para a apresentação de “Task scheduling algorithms for fog architectures”.

Abstract:

According to the author’s knowledge task scheduling in fog paradigm is highly complex and in the literature there are still few studies on it. In the cloud architecture, it is widely studied and in many researches, it is approached from the perspective of service providers. Trying to bring innovative contributions in these areas, we propose a solution to the context-aware task-scheduling problem for fog paradigm. In our proposal, different context parameters are normalized through Min Max normalization, requisition priorities are defined through the application of the Multiple Linear Regression (MLR) technique and scheduling is performed using Multi-Objective Non-Linear Programming optimization (MONLIP) technique.
