In this paper, we report on our experiments on the Yahoo! Labs Learning to Rank challenge organized in the context of the 23rd International Conference of Machine Learning (ICML 2010). We competed in both the learning to rank and the transfer learning tracks of the challenge with several tree-based ensemble methods, including Tree Bagging, Random Forests, and Extremely Randomized Trees. Our methods ranked 10th in the first track and 4th in the second track. Although not at the very top of the ranking, our results show that ensembles of randomized trees are quite competitive for the “learning to rank” problem. The paper also analyzes computing times of our algorithms and presents some post-challenge experiments with transfer learning methods. [less ▲]

Il y a plus de 10 ans, le réseau LEARN-NETT naissait de la rencontre de professeurs en sciences de l’éducation et était financé pendant trois ans, d’abord au niveau belge puis par la Communauté Européenne. Leur préoccupation ? Outre la formation aux usages des TIC dans les pratiques de formation, oeuvrer à la qualité de la formation pédagogique des futurs enseignants en les rendant davantage capables de travailler en équipe (apprentissage de la collaboration à distance) et d’assurer leur propre développement professionnel. Un élément particulier ? Le réseau LEARN-NETT est toujours actif. Ce mini-colloque sera décliné en trois parties. (1) Le dispositif pédagogique LEARN-NETT : les lignes de forces restées stables depuis 10 ans et les aspects qui ont évolué en fonction des avancées technopédagogiques. (2) Une des valeurs ajoutées de ce dispositif : la formation des tuteurs. Comment les tuteurs apprennent-ils leur fonction, développent-ils leurs compétences dans ce dispositif ? (3) Les bénéfices pour les différents acteurs de LEARN-NETT (enseignantschercheurs, tuteurs …), les perspectives nouvelles liées aux développements pédagogiques et technologiques, les conditions de survie et de développement d’un tel réseau et l’impact institutionnel d’un tel projet comme catalyseur de l’innovation pédagogique.

In this paper, scantling optimization a FSO offshore structure and a medium size capacity LNG gas carrier are presented. Optmization is based on the LBR5 least cost optimization package. Main originality and advantage is to combine the minimization of the construction cost with the preliminary design stage. The optimum scantling (least cost) is determined at the earliest design stage, this means before the signature of the contract. Cost savings of 5 to 10% are currently recorded. Relevant information on the methodology and applications to a FSO unit and a LNG carrier are presented in the paper. [less ▲]

The LBR-5 software allows optimizing ship structures according to objectives of higher inertia, less weight and/or lower cost. This last criterion offers the choice between two approaches of calculation. The first approach is based on a simplified assessment of the cost in which the total cost is described by rather simple analytical functions which bring into play on the one hand the design variables and on the other hand empirical parameters. In the second approach, the calculation of the cost is based on data specific to the shipyard. The material cost is analyzed according to the first approach while the cost of the labor considers each relevant operation of the ship building with respect to the LBR-5 model. A survey of all the tasks was carried out at Aker Yards France, and a thorough study made it possible to develop assessment tools of the labor cost for each operation as functions of the design variables. Plate straightening operations are also considered in this analysis. This paper presents a cost-based optimization study carried out on a large passenger ship structure with more than 600 design variables, by the use of the detailed approach for the cost calculation. The structural model has been formulated on the basis of technical documentation prepared by Aker Yards France. The loads and strength criteria applied on the model are considered according to classification society rules (Bureau Veritas). Results and conclusions of the study are presented. [less ▲]
