This thesis argues that the work of the artist David McDiarmid is to be read as an enactment of late twentieth century gay male and queer politics. It will analyse how both the idea and the cultural specificity of ???America??? impacted on the work of this Australian artist resident in New York from 1979 to 1987. The thesis examines how African American music, The Beats, notions of ???hip??? and ???cool???, street art and graffiti, the underground dance club Paradise Garage, street cruising and gay male urban culture influenced the sensibility and the materiality of the artist???s work. McDiarmid???s cultural practice of dress and adornment, it is proposed, forms an essential part of his creative oeuvre and of the ???queer worldmaking??? which is the driver of his creative achievements. The thesis proposes that McDiarmid was a Proto-queer artist before the politics of queer emerged in the 1980s and that his work, including his own life-as-art practices of dress and adornment, enact a mobile rather than fixed gay male identity.

La croissance exponentielle des données personnelles, et leur mise à disposition sur la toile, a motivé l’émergence d’algorithmes d’apprentissage de préférences à des fins de recommandation, ou d’aide à la décision. Les réseaux de préférences conditionnelles (CP-nets) fournissent une structure compacte et intuitive pour la représentation de telles préférences. Cependant, leur nature combinatoire rend leur apprentissage difficile : comment apprendre efficacement un CP-net au sein d’un milieu bruité, tout en supportant le passage à l’échelle ?Notre réponse prend la forme de deux algorithmes d’apprentissage dont l’efficacité est soutenue par de multiples expériences effectuées sur des données réelles et synthétiques.Le premier algorithme se base sur des requêtes posées à des utilisateurs, tout en prenant en compte leurs divergences d’opinions. Le deuxième algorithme, composé d’une version hors ligne et en ligne, effectue une analyse statistique des préférences reçues et potentiellement bruitées. La borne de McDiarmid est en outre utilisée afin de garantir un apprentissage en ligne efficace. / The rapid growth of personal web data has motivated the emergence of learning algorithms well suited to capture users’ preferences. Among preference representation formalisms, conditional preference networks (CP-nets) have proven to be effective due to their compact and explainable structure. However, their learning is difficult due to their combinatorial nature.In this thesis, we tackle the problem of learning CP-nets from corrupted large datasets. Three new algorithms are introduced and studied on both synthetic and real datasets.The first algorithm is based on query learning and considers the contradictions between multiple users’ preferences by searching in a principled way the variables that affect the preferences. The second algorithm relies on information-theoretic measures defined over the induced preference rules, which allow us to deal with corrupted data. An online version of this algorithm is also provided, by exploiting the McDiarmid's bound to define an asymptotically optimal decision criterion for selecting the best conditioned variable and hence allowing to deal with possibly infinite data streams.
