Abstract
The expansion of digital tools and participatory media created unprecedented possibilities for the maintenance and sharing of social memory and cultural identity knowledge. These possibilities are expanding in parallel with a context of an increasingly aged society, where elders are privileged keepers of regional cultural knowledge but often don’t have the opportunity to pass it on to future generations, making it prone to shortly disappear. This research approaches digital storytelling during intergenerational exchanges as a stage for a participatory contribution to the maintenance of cultural identity. We sought to determine how intergenerational dynamics can give place to cultural identity narratives, as well as how digital media can support the maintenance of cultural identity. For that purpose, we promoted the project NOOA: Narratives Of Our Age, with the premise of bringing generations together in sharing stories on topics such as Memories, Crafts, Myths, and Traditions, to endorse the continuity of the cultural identity of the Vale do Sousa region, using the potential of digital media in this process. With an action research design and an ethnographic approach, from 2018 to 2021, this project reunited three intergenerational groups, composed of participants aged 16 to 85 years old, in a set of activities designed to foster intergenerational dynamics. We sought to gather qualitative perceptions about the phenomenon of storytelling in the participatory maintenance of cultural identity through intergenerational dynamics. To this end, our research was based on data collected through detailed observations and through the application of semi-structured interviews and group discussions. We developed a five-step intergenerational storytelling framework to encourage the exchange of cultural identity knowledge, including digital registration, dissemination, and discussion in-person and online. This framework was submitted to a cyclical evaluation and its adjustments, in accordance with the action-research method, and it was implemented in three phases: phase one corresponded to a group dynamic component, through brainstorming and story planning; phase two corresponded to the creation of digital stories; phase three corresponded to dissemination, with the publication and sharing of these stories in the project’s digital spaces. These steps were conducted through in-person digital storytelling activities, in which cultural identity knowledge was shared and discussed in intergenerational partnerships, resulting in the participatory creation of 35 digital stories, that were afterwards shared and also discussed on the Project’s digital spaces. The outcomes of the activities, as well the enthusiasm and the reflections that occurred during the process, highlight the investment of participants in the transmission and maintenance of knowledge related to their experiences and knowledge acquired throughout life, in a family and community context. The observations of intergenerational dynamics, as well as the results of the semi-structured interviews, suggested a growing curiosity, involvement and overall understanding and retention of the stories of cultural identity, by both seniors and juniors, as well as a growing curiosity of senior participants regarding the pervasive digital reality presented to them by the juniors. Likewise, we observed the importance of empowering groups with spaces of sharing, both face-to-face and online, to enhance intergenerational exchanges around the knowledge of cultural identity. By promoting opportunities for intergenerational dialogue and empowering groups with face-to-face and online sharing spaces, we contributed with the development and application of a storytelling framework and digital spaces to safeguard, discuss and disseminate some of the specific cultural knowledge of the region of Vale do Sousa in Portugal. We observed the potential of using digital storytelling dynamics to break through barriers of communication between generations and to perpetuate and value cultural identity knowledge, acquired throughout life. This research goes beyond the aim of documenting the envisaged cultural identity knowledge, by combining creativity during the digital storytelling processes with connectivity among the participants on a community level, by sparking the dialogue between generations and enhancing the social impact of cultural identity knowledge and the self-knowledge value that generations are able to share through stories. We examined the opportunities and challenges of digital media as a platform and a catalyst for cultural identity maintenance, situating the problematic of cultural literacy in a contemporary setting. We conducted a thorough assessment of the stakeholders involved in participatory cultural identity maintenance in our present context, adding the observation of their synergies in a real context. This allowed us to examine the diversity of outcomes and the multiplicity of variables that contribute to it, as well as to grasp the impact that this new information flow paradigm may have on how we currently approach cultural identity maintenance.

Abstract
This project proposes a set of methods, inspired by the human experience of vision and time, for developing video sequences using trained generative models. The methods serve the production of video sequences, with patterns derived from trained models found in literature on metacreation and in the artworld. This project defines possible futures where the now pervasive generative models can be reused in computer simulations that focus on the human experience of video and mental images; models which, because of how they are trained through archives and records representing both the human and the physical world, can capture media themselves and represent specific moments in time.

The research outputs are in film and audiovisual installation, proposing that practice can further benefit from self-reference, using deep generative models as synthesisers of video, sound, and text. The methods produced take advantage of natural language guidance and deep generative models in ways that can be understood as sampling, sequencing, and translation, following computing literature and AI design. Each result can be understood in larger domains such as: 1) short films from text inputs, in the film Irreplaceable Biography; 2) discursive installations from video datasets, in the installation Time as meaning; and 3) short films from video inputs, in the film Man lost in the convergence of time and the collaboration all YIN no YANG. This research extends on the use of generative practice following a construct of language in the human mind, behaviour, and visual experience as inspiration for the experience of video. These projects further define what can be a broader understanding of directionality and representation of the past using systems of memory that learn, are networked and produced following structure found in nature and human experience.

Abstract

“Machine Learning (ML) relies on both data and algorithms for optimal functioning. While conventional ML research often emphasizes algorithmic improvements, the significance of data processing is frequently overlooked. In contrast, preprocessing data stands as a distinct task, executed before feeding it into algorithms. The diversity of preprocessing methods tailored for various ML algorithms underscores its importance. However, the feedback loop between algorithms and data is often neglected. Data-related issues pose significant challenges for predictive ML algorithms, adversely affecting forecasting accuracy. These challenges arise because problems in data are inherently unpredictable, lacking a discernible pattern. In this doctoral thesis, we introduce Read and Write Machine Learning (RW-ML), an innovative paradigm enhancing time series forecasting accuracy by integrating data modification techniques into the learning process. The RW-LSTM, an adaptation of the backpropagation algorithm, unifies preprocessing with recurrent neural networks (RNNs), significantly outperforming traditional models such as LSTM. RW-LSTM enables the transition from read-only RNNs, which merely learn from data, to RW-ML, allowing direct alterations for improved predictions. Expanding the framework, the Corrector Long Short-Term Memory (cLSTM) addresses the limitations of read-only RNNs, demonstrating enhanced forecasting accuracy through empirical verification and extensive experiments. The final chapter provides a real-world evaluation, highlighting the competitive advantage of cLSTM over LSTM models in various scenarios.”

Abstract
“Observation is central to most research methods independent of the paradigms used. From the observational roots of positivism to the subjective individual experiences of interpretivism, most, if not all, scientific studies require repeatedly observing features over time. Documenting observations and the processes used to acquire them, capturing the context of observations, and identifying relationships between observed features in a structured and meaningful manner is extremely important for the interpretability and reproducibility of research results. It is common that the effort preceding data processing, including steps such as data cleansing and structuring, vastly outweighs the time spent writing and tailoring the algorithms for processing and analysis. Therefore, having a conceptual framework instantiated in models, methods, and tools to effectively record observations in a structured way, independently of their nature, along with associated features and context, would help reduce the effort of preprocessing and potentially contribute to increasing the quality of results. Analogously, derived features resulting from the processing of the original observations can benefit from a similar approach, thus making the workflows on research data more explicit and reproducible. This research work is focused on the data collection and analysis stages of the research data lifecycle. It has been done in the context of diverse research projects, over several years, contributing to structure knowledge across different research domains. The research encompassed the identification of new needs, the design and prototyping of novel solutions, and their application to concrete high-demand environments to test, refine, and validate the proposed solutions, which are collectively consolidated as an enhanced approach for the lifecycle of research data. As a result, this work provided contributions of different types, of which we highlight observation templates and observation framework. These main contributions were validated in the context of the respective research projects and scientific publications.”

50 years of democracy: thinking the future!

What do we want the next 50 years of democracy to be like? What are the new challenges in a changing Europe? Will it be a different democracy from the one we have today?

These were some of the questions that journalist Eduarda Maio raised for discussion on “Consulta Pública”, Antena 1 programme, in its 15th episode on 2024, recorded on 24 April.

Henrique Lopes Cardoso, a lecturer at DEI and member of LIACC, was on the panel with Catarina Neves (Nova School of Business and Economics), José Neves (NOVA FCSH), Paulo Machado (Instituto Superior de Ciências Policiais e Segurança Interna) and João Cerejeira (School of Economics and Management, Universidade do Minho), and looked at the role of new technologies in general, and Artificial Intelligence in particular, as an enabler of democracy, leaving a positive message about the wealth of relevant applications in today’s society, although did point out that there are real concerns about the manipulation of technology and disinformation, something that in his opinion should be fighted with a growing commitment to digital literacy in all generations.

For 1h43m the five guests “thought the future of democracy”, exchanging opinions and arguments and bringing different opinions and perspectives on the subject to the discussion.

“Florensics” team wins TecStorm 2024

The awards ceremony of the 8th edition of TecStorm took place over the weekend of April 21-22, at the Champalimaud Foundation, where it honoured four projects by university students in the categories of Improving Lives through Connectivity, Energy Solutions for a Low Carbon Future, Health 4.0 and Data-Driven Sustainable Mobility Solutions.

Florensics, a team composed of Eunice Amorim, Francisco Pires and Lucas Santos, final year students of the Master in Informatics and Computing Engineering (M.EIC), was one of the winners of this edition, in the Improving Lives through Connectivity category, with a cash prize of 2,500 euros, sponsored by Vodafone.

The winning project is characterised by an innovative system based on IoT (Internet of Things), which consists of a network of devices (equipped with flame and carbon monoxide sensors, among others), strategically distributed throughout a forest area to collect data to prevent and fight fires more efficiently and earlier.

When asked about the experience, the team shares that TecStorm provided them with a unique experience that allowed to validate and present an idea with the potential to contribute to fire prevention, something especially relevant to our country. For 24 hours “we had the opportunity to put not only our engineering skills to the test, but also our teamwork, presentation, prototyping, planning and time management skills. We’re proud that our work has been recognised, and we’d like to thank all the organisers and participants who made this event a reality”, shares Lucas Santos.

TecStorm is the country’s largest technology competition, which encourages young entrepreneurship and the launch of innovative ideas capable of generating an impact on society.

It was created by JUNITEC, the junior company of the Instituto Superior Técnico, and stands out for being the oldest junior company in Portugal. Its core business is technological consultancy, where its mission is to realise projects with innovative technologies that have a high impact on society and bridge the gap between the student community and the business community.

Creativity Talks | “ ‘Design thinking’ and its relationship to other disciplinary approaches” by Prof. Nathan Crilly

Efforts to promote creativity often centre on encouraging people to engage in ‘design thinking’. Although this term has many different meanings, many of these meanings centre on the idea that even non-designers should behave more like designers. That is, people should treat whatever they are influencing as though it is something they are designing, whether that is a service, an organisation, some legislation, a piece of policy or anything else. The application of design thinking to these projects might include (amongst other things) an emphasis on developing an understanding for users, visualising ideas and iteratively testing prototype solutions. Although design thinking is often considered in isolation, it can easily be connected to approaches such as ‘systems thinking’ and ‘entrepreneurial thinking,’ which are also relevant to how problems are identified, framed and solved.

In this talk, Prof. Nathan Crilly will consider how these different approaches are related to each other, and how they are related to other similar approaches from other disciplines that might support us in undertaking creative work.

‘Design thinking’ and its relationship to other disciplinary approaches” will be presented April 23, at 6pm,  at the CTalks YouTube channel, moderated by Prof. António Lucas Soares (DEI).

All the information about the talk can be seen at the Creativity Talks webpage.

Nathan Crilly is Professor of Design at the University of Cambridge, where he researches human behaviour as it relates to design. This includes studying the behaviour of the people doing design work (e.g. designers’ creativity), and the experiences of those people who interact with design outcomes (e.g. users’ experiences). Nathan teaches design, creativity and communication at the undergraduate and postgraduate levels. He also teaches design thinking at the executive level, promoting innovation across a broad range of business sectors. Nathan plans, manages and conducts commercial research to deliver user insights for design projects focused on various markets, including consumer health, digital devices and sporting equipment.”
