Improved Riemannian potato field: an Automatic Artifact Rejection Method for EEG
No full textInternational audienceElectroencephalography (EEG) signal cleaning has long been a critical challenge in the research community. The presence of artifacts can significantly degrade EEG data quality, complicating analysis and potentially leading to erroneous interpretations. While various artifact rejection methods have been proposed, the gold standard remains manual visual inspection by human experts—a process that is time-consuming, subjective, and impractical for large-scale EEG studies. Existing techniques are often hindered by a strong reliance on manual hyperparameter tuning, sensitivity to outliers, and high computational costs. In this paper, we introduce the improved Riemannian Potato Field (iRPF), a fast and fully automated method for EEG artifact rejection that addresses key limitations of current approaches. We evaluate iRPF against several state-of-the-art artifact rejection methods, using two publicly available EEG databases, labeled for various artifact types, comprising 226 EEG recordings. Our results demonstrate that iRPF outperforms all competitors across multiple metrics, with gains of up to 22% in recall, 102% in specificity, 54% in precision, and 24% in F1-score, compared to Isolation Forest, Autoreject, Riemannian Potato, and Riemannian Potato Field, respectively. Statistical analysis confirmed the significance of these improvements (p < 0.001) with large effect sizes (Cohen’s d > 0.8) in most comparisons. Additionally, on a typical EEG recording iRPF performs artifact cleaning in under 8 milliseconds per epoch using a standard laptop, highlighting its efficiency for large-scale EEG data processing and real-time applications. iRPF offers a robust and data-driven artifact rejection solution for high-quality EEG pre-processing in brain-computer interfaces and clinical neuroimaging applications

Strong asymptotic freeness of Haar unitaries in quasi-exponential dimensional representations
No full text53 pagesInternational audienceWe prove almost sure strong asymptotic freeness of i.i.d. random unitaries with the following law: sample a Haar unitary matrix of dimension and then send this unitary into an irreducible representation of . The strong convergence holds as long as the irreducible representation arises from a pair of partitions of total size at most and is uniform in this regime. Previously this was known for partitions of total size up to by a result of Bordenave and Collins
Enseigner les Lumières depuis les Disability Studies
No full textInternational audienceIn his latest book (L'Héritage des Lumières. Ambivalences de la modernité, Seuil/Gallimard, 2019), Antoine Lilti distinguishes three main phases of Enlightenment criticism. The first, ‘conservative and reactionary’, present from the eighteenth century to the present day, pits faith against reason, tradition against progress, the family against the individual. The second, born in the wake of the Second World War, was initially Marxist-inspired (Adorno and Horkheimer), then critical of humanism (Foucault), and denounces the ‘excesses of reason and the forms of political domination it implies’. The third is postcolonial criticism, which, writes Lilti, ‘attacks the ideological substratum of European domination’, namely its (alleged) universalism (pp. 37-38). We present a fourth, generally neglected, critique of the Enlightenment, which has been unfolding in the English-speaking world since the 1990s, within a slightly older field of research, disability studies - or more precisely, cultural disability studies. In a way, this critique applies the main theses of the third approach to the issue of disability: the Enlightenment freed disability from the clutches of magical or religious interpretation, all the better to ensnare it in the clutches of reason, which excludes, rectifies and re-educates. The Enlightenment thus marked the transition from the moral model to the medical model of disability, which is still dominant today and sees disability as an unfortunate alteration or deficiency to be reduced as far as possible. The Enlightenment was not only racist and colonialist, it was also ableist: it forged the norm of the individual as not only rational and perfectible, but also autonomous and productive - in short, the able individual. While it would be beyond the scope of this chapter to assess the validity of such a diagnosis, we will ask the following questions: how does this critique from disability studies shed new light on the Enlightenment? What effects can or should it have on their teaching? After outlining the main features and the internal logic of this critique in the writings of its principal representatives, we show that its first effect is to offer the study of the Enlightenment nothing less than a new subject - ‘disability’, as it was then called - or a plurality of new subjects (blindness, deafness, etc.), taken into account, particularly in France, by its greatest authors.Dans son dernier ouvrage (L’Héritage des Lumières. Ambivalences de la modernité, Seuil/Gallimard, 2019), Antoine Lilti distingue trois grands phases de la critique des Lumières. La première, « conservatrice et réactionnaire », présente du XVIIIe siècle à nos jours, oppose la foi à la raison, la tradition au progrès, la famille à l’individu. La deuxième, née dans le sillage de la Seconde Guerre mondiale, d’abord d’inspiration marxiste (Adorno et Horkheimer), puis critique à l’égard de l’humanisme (Foucault), dénonce les « excès de la raison et des formes de domination politique qu’elle implique ». La troisième est la critique postcoloniale, qui, écrit Lilti, « s’attaque au substrat idéologique de la domination européenne », à savoir son (prétendu) universalisme (p. 37-38). Nous en présentons une quatrième, généralement négligée : la critique des Lumières qui se déploie dans le monde anglo-saxon à partir des années 1990, au sein d’un champ de recherches à peine plus ancien, les disability studies – plus précisément, les cultural disability studies. Cette critique consiste, en quelque sorte, à appliquer à la question du handicap les principales thèses de la troisième : les Lumières ont arraché le handicap aux griffes de l’interprétation magique ou religieuse pour d’autant mieux l’enserrer dans celles de la raison qui exclut, redresse et rééduque. Les Lumières signeraient ainsi le passage du modèle moral au modèle médical du handicap, qui, encore dominant aujourd’hui, conçoit celui-ci comme une altération ou une déficience malheureuse, à réduire autant que faire se peut. Les Lumières ne seraient pas seulement racistes et colonialistes, elles seraient aussi « validistes » (ableist) : elles auraient forgé la norme de l’individu non seulement rationnel et perfectible, mais encore autonome et productif – en somme, de l’individu capable (able). S’il ne saurait s’agir, en l’espace d’un chapitre, d’évaluer la validité d’un tel diagnostic, nous poserons les questions suivantes : en quoi cette critique issue des disability studies produit-elle sur les Lumières un nouvel éclairage ? Quels effets peut-elle ou doit-elle avoir sur leur enseignement ? Après avoir exposé, au moyen des textes de ses principaux représentants, les traits saillants et la logique interne d’une telle critique, nous montrons que son premier effet est d’offrir à l’étude des Lumières rien de moins qu’un nouvel objet – l’« infirmité », comme on la nommait alors – ou une pluralité de nouveaux objets (la cécité, la surdité, etc.), pris en vue, en France notamment, par ses plus grands auteurs
