Cognitive modeling is concerned with computational models of the mind or particular cognitive processes for the purposes of scientific comprehension and prediction of their performance and outcome regarding relevant input. It is the apex of Cognitive Science as it confronts and articulates the coherence of its disparate macro- and micro-level findings and bridges to its technological applications [1][2].
This talk aims at being an invitation to this most fascinating and challenging research area, which has gone through vigorous progress recently, as it is moving from being based merely on external representations of cognitive content or activity (e.g. text, pictures, etc.) to successfully take their neural-based representations into account (e.g. EEG, fMRI, etc.).
We highlight its major approaches, with their more prominent promises and challenges, from the ones based in logics to those based on deep neural networks.
Past and current research carried out in our Cognitive Science and Informatics Engineering postgraduation programs are briefly overviewed, which covers the modeling of grammatical knowledge [3][4], mood [5], semantics [6], emotions [7], reading [8], imagined speech [9] or olfaction [10], among others.
Cognitive modeling being a scientific endeavour on its own and confluent with AI, and given the awesome advances in so-called Generative AI, we focus on the ongoing debate about the prospects of AGI (Artificial General Inteligence) being reached soon [11][12][13], and the eventual relevance from and for cognitive modeling.
Short bio: António Branco is the Coordinator of the MA and PhD programs on Cognitive Science of the University of Lisbon (inter-faculties: Sciences, Letters, Medicine and Psychology).
He is a scientist from FCUL whose research is devoted to Artificial Intelligence and its subarea of Natural Language Processing, with a special focus on the technological preparation of the Portuguese language for the digital age, aiming thus at contributing to enhance the citizenship of its speakers in the information society.
