Workshop IA et Conscience / AI and Consciousness Workshop
2025-06-12 - 2025-06-13
Peut-on créer une intelligence artificielle consciente ? C’est la question que posera le workshop « Intelligence artificielle et conscience », organisé par l’ atelier 4 – Sciences cognitives et intelligence artificielle de Coggames , les 12 et 13 juin à l’ENS-PSL (Paris) .
Cet événement a pour but de favoriser des échanges interdisciplinaires sur la conscience, en croisant sciences cognitives, neurosciences, intelligence artificielle et robotique développementale. À une époque où l’IA et les grands modèles de langage transforment nos vies, il devient crucial d’explorer les convergences entre intelligence naturelle et artificielle, ainsi que les limites actuelles de la modélisation de la conscience.
ℹ️ Participation gratuite — merci de vous inscrire pour faciliter l’organisation : https://iaetconscience.sciencesconf.org/
Organisateurs : Alexandre Pitti, Nicolas Spatola, Rufin VanRullen, Laura Cohen

AI and Consciousness Workshop – June 12–13 in Paris
Can we create a conscious artificial intelligence? This is the central question of the “Artificial Intelligence and Consciousness” workshop, organized by Atelier 4 – Cognitive Science and Artificial Intelligence of Coggames , taking place on June 12–13 at ENS-PSL in Paris .
The goal of this event is to foster interdisciplinary dialogue on consciousness , bridging cognitive science , neuroscience , artificial intelligence , and developmental robotics. At a time when AI and large language models are transforming our lives, it is essential to explore the convergences between natural and artificial intelligence , and the current limits of modeling consciousness.

Spectral Imaging for Cultural Heritage: Past, Present, and Future
During the last few decades, spectral imaging has proven to be a very useful technology for the precise documentation and non-destructive analysis of tangible cultural heritage objects [1-5]. With spectral imaging we here include various imaging technologies which allow to measure the spectral reflectance of the objects at a large number of spatial locations of the object in one operation. These technologies vary greatly in key parameters such as spatial resolution (number of pixels), spectral resolution (number of channels), cost, and time and complexity required to capture high quality images.
In this talk we will first introduce the principles of spectral imaging, before discussing how this type of imaging can be useful in the field of cultural heritage [3,4]. Then we will present and discuss examples of our recent and ongoing research in this field, for instance on the topics of pigment mapping in paintings [2,5,6,7], hyperspectral analysis of stained glass windows [8], analysis of historical textile fragments from the Viking age, and visualization of hyperspectral images. Finally, considering the challenging task of properly assessing the quality of a spectral image [3,9], we will discuss the question of how many spectral channels we actually need in a spectral imaging system [10,11].

Using multimodal AI to support the preservation of Cultural Heritage under Climate Change
Heritage materials are increasingly vulnerable to the effects of climate change. Fluctuations in temperature, humidity, and other environmental factors can accelerate the degradation of monuments, yet predicting this weathering remains complex due to the wide range of influencing variables i.e. material properties, conservation conditions, and human activity among them. In this talk, we will explore how artificial intelligence, and in particular multimodal machine learning, can help address this challenge. By integrating diverse types of data i.e. scientific images, in situ sensor readings, and environmental records, we aim to better understand and anticipate material deterioration across time and context. Our work focuses on three French heritage sites: Strasbourg Cathedral, the Bibracte archaeological area, and the Saint-Pierre Chapel. These sites serve as case studies for developing AI models capable to predict a degradation index under different climate scenarios and opens new perspectives for long-term cultural heritage conservation planning.
