HISTOIRESMORALES: A French Dataset for Assessing Moral Alignment
No full textInternational audienceAligning language models with human values is crucial, especially as they become more integrated into everyday life. While models are often adapted to user preferences, it is equally important to ensure they align with moral norms and behaviours in real-world social situations. Despite significant progress in languages like English and Chinese, French has seen little attention in this area, leaving a gap in understanding how LLMs handle moral reasoning in this language. To address this gap, we introduce HISTOIRESMORALES, a French dataset derived from MORALSTORIES, created through translation and subsequently refined with the assistance of native speakers to guarantee grammatical accuracy and adaptation to the French cultural context. We also rely on annotations of the moral values within the dataset to ensure their alignment with French norms. HISTOIRESMORALES covers a wide range of social situations, including differences in tipping practices, expressions of honesty in relationships, and responsibilities toward animals. To foster future research, we also conduct preliminary experiments on the alignment of multilingual models on French and English data and the robustness of the alignment. We find that while LLMs are generally aligned with human moral norms by default, they can be easily influenced with user-preference optimization for both moral and immoral data
JC3DHN 2024 - Actes du colloque
No full textInternational audienceCet ouvrage rassemble les actes du colloque du Consortium 3DHN, qui s’est tenu du 26 au 28 novembre 2024 à Nancy. Le Consortium-HN-3DHN est un réseau national, labelisé par l’IR * Huma-Num, qui fédère des équipes de recherche ainsi que des institutions patrimoniales, œuvrant pour le développement, la structuration et la diffusion des bonnes pratiques liées à la production, la gestion, la conservation et la valorisation des données 3D dans le domaine des sciences humaines et sociales.À travers ses actions collectives, le consortium-HN-3DHN poursuit plusieurs objectifs majeurs : accompagner les chercheurs et les acteurs du patrimoine dans l’usage raisonné et critique des technologies 3D. favoriser l’interopérabilité des données 3D, promouvoir les principes FAIR et encourager l’adoption de standards ouverts.Le colloque de Nancy a constitué un moment privilégié d’échange et de réflexion sur ces thématiques et a permis de confronter les expériences, discuter des méthodologies, et d’explorer les perspectives offertes par les approches 3D au sein des Humanités Numériques.L’ensemble des interventions du colloque est consultable sur la chaîne du consortium 3DHN, hébergée sur la plateforme audiovisuelle de l’enseignement supérieur et de la recherche Canal-U (https://www.canal-u.tv/chaines/c3dhn

Aberration and self-reconstruction of zero-order Bessel beams in isolated and array format generated using positive and negative axicon lenses
No full textInternational audienceBessel beam arrays, which can be created involving multiple axicons, diffractive elements, and interference effects, can experience several types of aberrations that distort their ideal characteristics, limiting their applications in microscopy, photonics, and material processing. For instance, Tilt aberration occurs when the individual axicons or optical elements in the Bessel beam array generation setup are misaligned or tilted relative to each other. This tilt can affect the beam's quality, focusing ability, and propagation characteristics. The present study experimentally investigated how any tilt associated with the axicon lens (of both positive and negative surface profile) affects the spatial characteristics of Bessel beams in isolated as well as in array formats. In particular, the aberration characteristics of [1x7] Bessel beam arrays of conical half-angle up to 11 degrees were studied. The spatial filtering of Bessel beam arrays was also demonstrated.</div
Fabrication and characterization of high performance sub-millimetric InGaP/InGaAs/Ge solar cells
No full textInternational audienceMicro-Concentrator photovoltaics modules promise to overcome the limitations of CPV such as thermal losses or resistive losses. Miniaturization involves new challenges in the field of cells fabrication, particularly the management of perimeter recombinations. In this paper, sub-millimetric InGaP/InGaAs/Ge solar cells with high performances are fabricated. We report record open circuit voltage of 2.39 V and 2.28 V for cells with mesa area of 0.25 mm 2 and 0.04 mm 2 respectively, indicating excellent sidewall passivation. Individual assessment of sub-cells non-radiative losses indicates that the top cell is the most impacted by perimeter recombinations.</div
