DEI TALKS | “Architectures for building Extraordinary Software” with Joseph Yoder, Graziela Simone Tonin, Neil Harrison and Filipe Correia

When building complex systems, it can be all too easy to primarily focus on features and overlook software qualities, specifically those related to the architecture. Pressure to adapt to and shape the market requires organizations to add new features, accommodate new interactions, and have new teams work on adapting the software. Some believe that by simply following Agile practices—starting as fast as possible, keeping code clean, and having lots of tests—a good architecture will magically emerge. While an architecture will emerge, if there is not enough attention paid to the architecture and the code, technical debt, and design problems will creep in until it becomes muddy, making it hard to deliver new features quickly and reliably. Sometimes a straightforward software architecture that starts out small when communication is easy can support guided, incremental architectural changes and can gradually evolve with its environment, remaining fit for its purposes. Other times it is not so simple: the initial software architecture can be poorly suited for supporting required changes, or the accumulation of suboptimal architectural decisions (also known as architectural technical debt) can be too severe. It is essential to have a sustainable architecture that can evolve through the project life-cycle. Sustainable architecture requires ongoing attention, especially when there are evolving priorities, a lot of technical risks, and many dependencies. This will be a roundtable spirited discussion by invited panelists and participants discussing architectural considerations for designing systems, specifically on architectures for building excellent software.

“Architectures for building Extraordinary Software” will be presented February 7, 15:00-16:15, in room B033 and will be moderated by Carlos Duarte (DEI).

DEI TALKS | “Analyzing and Modeling Intelligent Systems Users’ Behavior in Digital Society” by Prof. Humberto Marques-Neto

“Information systems are ever-increasingly intelligent and present in the daily lives of people and companies, facilitating and modifying the performance of various activities. In addition to handling each system’s intrinsic data, data from its users’ interactions can contribute to identifying, modeling, and analyzing people’s behavior patterns. The data analysis from the usage of web systems and mobile applications and, in particular, from online social networks such as Twitter, Facebook, WhatsApp, Instagram, and TikTok (obviously respecting the privacy of users) can contribute to the understanding of some dynamics and specific behaviors of human beings.

In this talk, I will present how our research group has done the characterization, analysis, and modeling of the behavior of users of intelligent information systems, more specifically, users of online social networks and information systems that make information available in open data portals, to induce the development of new software that use machine learning and artificial intelligent algorithms. The information systems user behavior, together with patterns of social interaction and human mobility in urban centers, in addition to subsidizing decisions and policies of government agencies and institutions responsible for urban planning, could foster and even target software developers interested in creating innovative software with the potential to improve people’s lives in a digital and connected society.”

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…

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.
