DEI TALKS| “Aprendizado colaborativo em redes neuronais artificiais” by Prof. Areolino de Almeida Neto

“Any task that cannot be carried out by a single agent requires the interaction of multiple agents aligned with the solution to the problem. Teamwork usually requires coordination between the members so that there are no conflicts and the result is more efficient. In the field of artificial learning, when one element is unable to fully learn the solution to a problem, it requires the participation of other “intelligent” elements to fully learn the solution. In this way, a collaborative learning system is presented, in which intelligent agents learn to collaborate with each other in order to achieve complete learning in a self-coordinated way (without a coordinator) and without the occurrence of conflicts between the intelligent elements. Specifically, it involves inserting other neural networks or other intermediate layers into an ANN in order to collaborate with the learning already acquired and thus add new knowledge to the system.”

This is how Prof. Areolino de Almeida Neto describes his presentation entitled “Collaborative learning in artificial neural networks”, which will take place on 15 November at 14:30, room B033.

The talk will be moderated by Prof Carlos Soares (DEI).

DEI TALKS | “From Numerical Libraries, To Efficient Matrix Multiplication Compiler-Only Code Generation, To a Modular Automated General Packing Data Transformation” by Prof. J. Nelson Amaral

By the author:

“To support both Artificial Intelligence and High-Performance Computing workloads, new processors have introduced hardware acceleration for matrix multiplication. Examples include the Matrix Multiply Assist (MMA) in the IBM POWER10 and the Advanced Matrix Extensions (AMX) in the Intel Sapphire Rapids microarchitecture for Xeon servers. This talk describes how, in a collaboration between the University of Alberta, the University of Campinas, and IBM, we developed compiler technology to support such accelerators. An initial solution delivered a robust pattern matcher for General Matrix Multiplication (GEMM) computation operating at the LLVM intermediate representation that allows the replacement of the computation with an invocation of a high-performance library. A later solution delivered a compiler-only path for code generation by adapting the layered approach used in numerical libraries to the compiler code-generation process. Finally, a modular and automated general strategy for data packing, which can be applied to multiple algorithms, was developed for the Multi-Level Intermediate Representation (MLRI).”

From Numerical Libraries, To Efficient Matrix Multiplication Compiler-Only Code Generation, To a Modular Automated General Packing Data Transformation” will be presented July 17, at 11:30, room B006, moderated by Prof. Pedro Diniz (DEI) and co-organized by DEI Talks and the University of Porto – Faculty of Engineering ACM Student Chapter.

DEI Talks | “Research, teaching and services in Biomechanics: a virtuous marriage with informatics” by Prof. João Paulo Vilas-Boas

The Porto Biomechanics Laboratory (LABIOMEP-UP) was created with the intention of bringing together the efforts of the critical mass of the University of Porto in the fields of Biomechanics, whether dedicated to teaching, research and university extension, in the fields of sports, forensics, clinical, health and safety, ergonomics, etc. It is, therefore, a unit whose vocation is transversal to most of the University’s territories and, therefore, eminently trans and interdisciplinary.

Dedicated to the study of the causes and effects of forces and tensions generated and applied by and to biological systems and prosthetic and orthotic devices, LABIOMEP-UP uses the measurement and processing of data related to internal and external forces to biological systems and their effects, namely kinematics and plastic adaptations. The operating domains extend from dynamometry to kinemetry, passing through electromyography, morphometry (internal – using medical imaging – and external – using planar and 3D geometries extraction), thermography, and bioenergetics. In any of these spaces, and particularly in the domain of its cross and integrated interpretation, information technology is recurrently present, either through “customer” applications or through dedicated solutions aimed at solving specific problems. This is, obviously, a virtuous marriage: one that flows without great tension being perceived between the merits and limitations of each party. On the contrary: they can no longer live without each other…

 “Research, teaching and services in Biomechanics: a virtuous marriage with informatics” will be presented June 28, 15:00, room B011 at FEUP, moderated by Prof. Rui Camacho (DEI).

CreativityTalks | “The creative individual: from the confluence of requirements to cognition challenges” by Fátima Morais

The twelfth session of Creativity Talks will have as speaker the distinguished researcher from the University of Minho, Fátima Morais, about “The creative individual: from the confluence of requirements to the challenges of cognition”.

“Creativity is explained in the conception of a network of interacting variables, personal and social. However, the focus of this work will be on the individual, the initial actor in the gestation of a creative idea.  Rather than trying to answer what creativity is, it will reflect what a creative individual requires – the term ‘requirements’ potentially implies the operationalization of concepts, hence a proactive and concrete stance of promotion. In this context, after understanding the creative individual as a confluence of different dimensions, his or her cognition will be targeted in greater detail. The creative cognitive processes are the tools that typically mark, in quality and in greater frequency of use, the individuals who provoke innovation. This analysis will carry the responsibility that such tools are applied and promoted in everyone’s daily life – several examples of this educational challenge will be shared. It is hoped that such sharing will allow new ideas in the practices of those who listen to us”.

Maria de Fátima Morais has a degree in Psychology from the University of Porto and a PhD in Educational Psychology from the University of Minho. At the latter University, she is an Assistant Professor at the Institute of Education. She is a researcher at the Centre for Research in Education (CIEd) at the University of Minho. She is a member of the National Association for the Study of Intervention in Overgiftedness (ANEIS) and of the International Network for Research, Intervention and Evaluation in High Intellectual Abilities (REINEVA). She belongs to the Scientific and Editorial Board of some journals. She has been a consultant for associations that study and promote creativity (e.g. Torrance Center Portugal; ANEIS) and has published nationally and internationally on this subject.

The session will take place on June 22, at 18:00, in room B008 of FEUP, and will be moderated by Manuel Firmino Torres, Professor at DEI. It will also be broadcasted via Youtube.

The entrance is free but registration is required.

DEI Talks | “Internet of Things and Security” by Prof. Mostafa Azizi

“Internet of Things and Security” will be presented on Wednesday, June 21, at 14:45, in room B006, moderated by Prof. António Pimenta Monteiro, from DEI.

By the Author:

“Internet of things (IoT) as a new discipline has emerged since more than two decades, it is a technology vision to widen the classic Internet by integrating new applications and connecting
physical devices (such as sensors, actuators …). Reinforced by AI, IoT has gained a broad presence over different economic sectors, namely industry, agriculture, transportation, logistics, health, management of cities and homes … According to some criteria of energy autonomy, distance and smartness level, several connection types and protocols are available. Similarly as for the OSI or TCP/IP models for computer networks, IoT could be also perceived as a succession of at least three layers (Edge layer, Fog layer, and Cloud layer). Some connection protocols, such as RFID, ZigBee, WIFI, NB-IoT, and LoraWAN, are used for the communication infrastructure, while other protocols such as MQTT, CoAP, and HTTP are considered at the application level. With the advent of Industry 4.0, the proliferation of IoT was intensified, leading to the emergence of smarthomes, smartcities, smartfactories, industrial IoT (IIoT), Medical IoT (MIoT) … IoT combined with AI and data engineering is transforming our daily lives and environments. Meanwhile, this wide use of IoT is facing real security threats that could disrupt the availability of the services or inject fake data streaming. Unfortunately, most of the used devices are not prepared to protect themselves, and do not assure the least level of security. In this talk, we will present some concepts, technologies, and applications of IoT; then, we will deal with the IoT security aspect and raise awareness on this topic.
Keywords: IoT/IIoT, Industry 4.0, Smart devices, AI, IoT layers, IoT protocols, Security.

Mostafa AZIZI received a State Engineer degree in Automation and Industrial Computing from the Engineering School EMI of Rabat, Morocco in 1993, then a Master degree in Automation and Industrial Computing from the Faculty of Sciences of Oujda, Morocco in 1995, and a Ph.D. degree in Computer Science from the University of Montreal, Canada in 2001. He also earned tens of certifications in Programming, Networking, AI, Computer Security … He is currently a Professor at the department of computer engineering, ESTO, University Mohammed 1st of Oujda. His research interests include Security and Networking, AI, Software Engineering, IoT, and Embedded Systems. His research findings with his team are published in over 100 peer-reviewed communications and papers.

CreativityTalks | “The Creativity Virus” by Katja Tschimmel

Creativity is one of our most precious human resources. We owe to it our civilisation, our culture, and every benefit that arts, science or technology offer. Today, we live on the results produced by creative people over the ages. In this sense, creativity is inexhaustible. Creativity creates creativity. We can define creativity as the capacity to transform ideas and knowledge to obtain new knowledge. Creative thinking and action create new creative thinking and action. Creativity is contagious, and so infects the people around us. This is the idea which will be explored in Katja Tschimmel’s talk. In this approach, she will not focus only on the creative individual – the artist, the designer, the writer or the scientist – but she wants to understand the creative person as an integral part of a complex system. A living system which can be a group of people, a team, an organisation, a city or/and the whole society. This Creativity Talk aims to infect the audience with creativity by 1. offering knowledge about the creativity phenomenon and 2. inspiring the generation of new ideas and knowledge through information, images and short thinking exercises.

 “The Creativity Virus” will be presented by Katja Tschimmel on May 4, at 6 pm, room B021. The session will be moderated by Prof. João José Pinto Ferreira and will also be streamed via Youtube

Free entrance but registration required.

DEI Talks |”Network construction from data and network visualization” by Prof. Eliška Ochodková

“Network construction from data and network visualization” will be presented on Wednesday, April the 26th, at 14:30, room I-105, moderated by Prof. Rui Camacho from DEI.


By the author:

The lecture will show how to extract data from vector data in the form of a network – and how the analysis of the constructed network helps to improve the results of classical datamining, e.g. to reveal otherwise undetectable relationships.  The advantage of networks is that the data is extended with links between certain (similar) pairs of data objects.

If we focus on biomedical data, the network approach is one of the innovative multivariate approaches to analyze complex biomedical datasets.  Patient profile similarities are essential for observers to study and visually assess relationships between groups of similar patients, and to do this, patient data is converted into a patient similarity network.



Dr. Eliška Ochodková is an assistant professor at the Department of Computer Science, Faculty of Electrical Engineering and Computer Science, VŠB – Technical University Ostrava. She holds a Master’s degree in computer science from Palacký University in Olomouc and a PhD degree in computer science ( in cryptography) from VŠB – TU Ostrava.

Her research interests are social network analysis (network science) and bioinformatics, focusing on the analysis of biomedical data using network construction from biomedical data.  Currently she is also working on new methods for protein complex detection and information processing and retrieval from microarray data.

She teaches both undergraduate and graduate courses related to data analysis and cryptography. She is a Deputy Head of the Department of Computer Science at home university.


DEI Talks | “At the intersection of job quality and innovation” by Prof. Christopher Mathieu

At the intersection of job quality and innovation” will be presented on Wednesday, April the 12that 14:30, room B021, moderated by Prof. António Coelho from DEI.

By the author:

“The link between innovation and job quality is increasingly elaborated in empirical studies (Duhautois, et al. 2020; Laursen & Foss 2014; Mathieu & Boethius 2021, 2022; Muñoz de Bustillo, et al. 2022). Job quality has been found to be linked to both the generation of innovations as well as the implementation of externally generated innovations at the workplace level. This presentation examines the mechanisms and cumulative factors behind these processes drawing primarily from a Horizon 2020 project ( examining the generative relationship between job quality and innovation in nine industries, from computer games to healthcare, across the EU (Mathieu & Boethius 2021, 2022).”

Chris Mathieu is a sociologist of work and organization at the Department of Sociology, Lund University. From 2003-2014 he was at the Department of Organisation, Copenhagen Business School. His primary field of research is the organization and quality of working life. From 2015-2018 he was coordinator of the Horizon 2020 project QuInnE ( – Quality of Jobs and innovation Generated Employment Outcomes. In this project he was responsible for studies of innovation and work in the computer games industry and specialist healthcare. He was editor of the Oxford Handbook of Job Quality (OUP, 2022) with Chris Warhurst and Rachel Dwyer. In addition to innovation, job quality and employment issues, he has also published widely on specialist surgical training, gender in organisations, and cultural policy and production, especially inter-occupational collaboration and career in the film industry (see Mathieu & Visanich (2022) Accomplishing Cultural Policy in Europe: Financing, Governance and Responsiveness; Mathieu (2012) Careers in Creative Industries, Routledge).

CreativityTalks | “The End of Programming (as we know it)” by Prof. Cristina Videira Lopes

“This talk is an exploratory tour through this brave new world, and its consequences to our field and to Computer Science (CS) education,” anticipates the speaker of a presentation on a topic that due to the advances in Artificial Intelligence (AI) in “Large Language Models (LLMs)”, mediately exposed by ChatGPT, promises to revolutionise software development.

“The End of Programming (as we know it)” will be presented by Prof. Cristina Videira Lopes, with moderation by Prof. João Paulo Fernandes, on March 23, 18:00, room B035, with online broadcasting via Youtube.

By the speaker: “For the past 80 years, “programming” meant translating a high-level, semi-formal specification of a desired effect from natural language into computer instructions, using an artificial programming language. Mastering these translations requires domain knowledge of algorithms and data structures, talent, and years of practice. Large Language Models (LLMs) are disrupting the very notion of “programming.” The disruption is profound, and at two levels: (1) LLMs are capable of doing those translations automatically, and (2) many of the desired effects can be obtained without the use of algorithms or data structures. This talk is an exploratory tour through this brave new world, and its consequences to our field and to CS education.”


Cristina (Crista) Lopes is a Professor in the School of Information and Computer Sciences at University of California, Irvine, with research interests in Programming Languages, Software Engineering, and Distributed Virtual Environments. She is an IEEE Fellow and an ACM Distinguished Scientist. She is the recipient of the 2016 Pizzigati Prize for Software in the Public Interest for her work in the OpenSimulator virtual world platform.

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

“Computational Inaesthetics: Expanding the Boundaries of Artistic Research and Computational Aesthetics” will be presented on Friday, march 24th, at 14:30, room I-105, moderated by Prof. António Coelho from DEI.

By the author:

“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.
