Der volle Inhalt der QuelleLa deuxième partie est consacrée aux jeux d'évolution, et étudie le lien entre l'issue de processus évolutifs et les concepts stratégiques statiques. Nous montrons notamment que les dynamiques d'évolution peuvent éliminer toutes les stratégies appartennant au support d'au moins un équilibre corrélé, et ce pour n'importe quelle dynamique monotone et pour des ensembles ouverts de jeux et de conditions initiales. L'élimination de toutes les stratégies dans le support des équilibres de Nash se produit sous toutes les dynamiques d'adaptation myope régulières et, sous la dynamique des réplicateurs ou la dynamique de meilleure réponse, à partir de presque toutes les conditions initiales.
La troisième partie, co-écrite, étudie les déterminants de la séparation entre lignée germinale et lignée somatique chez les algues vertes volvocales.

Der volle Inhalt der QuelleThis thesis takes place within the theory of prediction of individual sequences. The latter avoids any modelling of the data and aims at providing some techniques of robust prediction and discuss their possibilities, limitations, and difficulties. It considers issues arising from the machine learning as well as from the game-theory communities, and these are dealt with thanks to statistical techniques, including martingale concentration inequalities and minimax lower bound techniques. The obtained results consist, among others, in external and internal regret minimizing strategies for label-efficient prediction or in games with partial monitoring. Such strategies are valuable for the on-line pricing problem or for on-line bandwidth allocation. We then focus on internal regret for general convex losses. We consider first the case of on-line portfolio selection, for which simulations on real data are provided, and generalize later the results to show how players can learn correlated equilibria in games with compact sets of strategies

Der volle Inhalt der QuelleThe sense of verticality is a major spatial referential for perception and action in space. It allows determining our body position relatively to the gravity and it contributes to the organization of the postural control in humans. The assessment of the sense of verticality for a better understanding of postural and spatial disorders in stroke patients becomes common practice. However, the lack of standardization and psychometrical studies of the verticality perception assessment limits considerably the clinical integration of these tools and the development of therapeutic clinical trials for the follow-up of postural disorders in neurological diseases. Stroke is also the primary model for studying the sense of verticality. The identification of neural bases underlying the multisensory integration processes of the sense of verticality is based essentially on modern techniques of lesion analysis. However, our knowledge of the neural bases of the construction and updating of the sense of verticality are partial and require further studies. Our research aimed to improve our understanding of the sense of verticality through study of these disorders after stroke, according to a methodological and physiopathological dual approach. We showed that the assessment of the visual vertical perception after stroke requires a specific postural setting (the trunk and the head maintained upright in stroke patients with postural disorders) and should be based on 10 trials to achieve a high inter-trials reliability. Under these conditions, visual vertical orientation has excellent inter- and intrarater reliability, ensuring the reliability of this measure for both clinical practice and research. For the postural perception of the vertical, we proposed a simplified and standardized procedure with the wheel test to assess contralesional postural vertical biases after hemispheric stroke. Finally, by means of a lesional statistical analysis, we identified a cortical and subcortical areas network of the visual and postural vertical perception. The polymodal regions of the sense of verticality are centered on the operculo-insular cortex and the posterolateral thalamus, with a right hemisphere predominance and a partial overlap with the core regions of the vestibular cortex. Our results provide a better understanding of the neural bases of the sense of verticality in humans and constitute guidelines for the clinical use of the verticality perception measures.Keywords: Sense of verticality, stroke, assessment methodology, neural bases, vestibular cortex
