Feature generation is the problem of automatically constructing good features for a given target learning problem. While most feature generation algorithms belong either to the filter or to the wrapper approach, this paper focuses on embedded feature generation. We propose a general scheme to embed feature generation in a wide range of tree-based learning algorithms, including single decision trees, random forests and tree boosting. It is based on the formalization of feature construction as a sequential decision making problem addressed by a tractable Monte Carlo search algorithm coupled with node splitting. This leads to fast algorithms that are applicable to large-scale problems. We empirically analyze the performances of these tree-based learners combined or not with the feature generation capability on several standard datasets. [less ▲]

Durant cette communication, à la suite des travaux d'Anne-Marie Lecocq (1987), nous sommes revenus sur le discours héraldique de la comtesse et duchesse d'Angoulême, Louise de Savoie, l'influente mère de François Ier. Nous avons présenté et explicité ses devises favorites, à savoir la cordelière, qui évoque autant le nœud de Savoie que la cordelière franciscaine, le vol, sans doute choisi puisque l’aile évoque le L de Louise par homophonie, le bouquet de lis ou le cygne « navré », mais aussi les écus et les monogrammes qui lui sont associés et qui ponctuent enluminures, tapisseries, bas-reliefs et éléments sculptés de l’architecture. Notre intention a été de montrer d’une part comment Louise de Savoie manifeste, par l’intermédiaire de ces signes emblématiques, son identité et son pouvoir, d’autre part comment elle construit, par leur biais, un patrimoine, mental, susceptible de renforcer son clan et ses héritiers.

Research suggests that states of the body, such as postures, facial expressions, and arm movements, play central roles in social information processing. This study investigated the effects of approach/avoidance movements on memory for facial information. Faces displaying a happy or a sad expression were presented and participants were induced to perform either an approach (arm flexion) or an avoidance (arm extension) movement. States of awareness associated with memory for facial identity and memory for facial expression were then assessed with the Remember/Know/Guess paradigm. The results showed that performing avoidance movements increased Know responses for the identity, and Know/Guess responses for the expression, of valence-compatible stimuli (i.e., sad faces as compared to happy faces), whereas this was not the case for approach movements. Based on these findings, it is suggested that approach/avoidance motor actions influence memory encoding by increasing the ease of processing for valence-compatible information. [less ▲]

Si un récit romanesque peut accueillir en abyme une réplique en miniature (Lucien Dällenbach), si, dans le même esprit, un tableau de peinture peut ouvrir son espace à un autre tableau de peinture (Victor Stoichita), l’image de cinéma n’est pas en reste à cet égard : très tôt, elle s’est mise au miroir, par le procédé devenu canonique du film dans le film. En pareil cas d’espèce, le film premier convoque un film second, identifiable ou non, qui en constitue la glose ou la mise en ironie, selon des structures de redoublement variables. J'aborde ce phénomène de métadiscursivité au travers de deux sites d’images spécifiques : d’une part, le cinéma des premiers temps ; de l’autre, le cinéma expérimental contemporain. Dans le champ du cinéma des premiers temps, il s’agit d’examiner des occurrences assez précoces de réflexivité, au sein desquelles l’image seconde tient essentiellement lieu d’embrayeur narratif. Ainsi, dans "Erreur tragique" (1912) de Louis Feuillade, le personnage principal, assistant à une projection dans une salle de cinéma, a la surprise de voir apparaître sa propre épouse à l’écran, au bras d’un autre homme – prélude à un intense mélodrame conjugal. S’agissant du cinéma expérimental contemporain, l’image seconde se prête généralement à un enchâssement plus complexe au sein du film qui l’inclut et obéit plutôt à une exigence d’interrogation critique du cinéma par lui-même. Ce cas de figure sera envisagé au travers de "Tails" (1976) de Paul Sharits, œuvre méconnue dans laquelle le cinéaste, prolongeant le geste pionnier de Ken Jacobs ("Tom, Tom, the Piper’s Son", 1969), refilme des fragments de pellicule en mouvement et libère l’image seconde des contraintes imposées par le dispositif de projection, la mettant en situation de discourir muettement sur les propriétés physiques du film qui l’expose.

The aim of this study is to judge the effectiveness of the new treatment of varicoceles, introduced in 1987 by Tauber: the antegradal scrotal sclerotherapy of varicoceles. From february 1996 to april 1998, we have realised 150 antegrade embolisations of varicoceles. The study is lead on 75 patients with mean time follow-up of 12 months. Patient's mean age is 20 years. 85% of patients had a grade 3 left varicocele and 15% a grade 2 left varicocele. The criterium of success rests on the lack of veinous flow-back during clinical examination, which is than confirmed by doppler-ultrasound. Clinical success is obtained in 87% of the cases and the doppler control is normal in 80% of the cases. We have 9% of minor complications, and no major complication. The number of failures in our study is higher than in Tauber' study, but is the same as those described in the other procedures of treatment of varicocele. On the other hand the surgical procedure is simple and the morbidity is low. [less ▲]

To regain the SPF status of a contaminated but genetically valuable rabbit breeding unit, embryos from the contaminated does were transferred into SPF recipient females. Embryos were collected on day 3 of gestation by flushing uterine horns. All usable embryos were frozen, part of them were not transferred and kept in liquid nitrogen forming a stock of highly valuable genotypes. Thirty-two stimulated does produced 893 embryos, among which 821 (92%) had an intact zona pellucida and were cryopreserved. From this stock, 478 embryos were thawed, 466 were recovered (97.5%) and 417 were of good quality (87.2%). In 30 does, 10 to 18 embryos were surgically transferred per recipient doe and 24.9% (104/417) of them developed to term after transfer. This corresponds to an average number of 3.47 (104/30) live newborns per recipient. Health screenings performed on sanitized rabbits confirmed the disappearance of pathogenic agents. [less ▲]

In oil-storing Brassica napus (rape) seeds, starch deposition occurs only transiently in the early stages of development, and starch is absent from mature seeds. This work investigates the influence of a reduction of ADP-Glc pyrophosphorylase (AGPase) on storage metabolism in these seeds. To manipulate the activity of AGPase in a seed-specific manner, a cDNA encoding the small subunit of AGPase was expressed in the sense or antisense orientation under the control of an embryo-specific thioesterase promoter. Lines were selected showing an embryo-specific decrease in AGPase due to antisense and cosuppression at different stages of development. At early developmental stages (25 days after flowering), a 50% decrease in AGPase activity was accompanied by similar decreases in starch content and the rate of starch synthesis measured by injecting (14)C-Suc into seeds in planta. In parallel to inhibition of starch synthesis, the level of ADP-Glc decreased, whereas Glc 1-phosphate levels increased, providing biochemical evidence that inhibition of starch synthesis was due to repression of AGPase. At 25 days after flowering, repression of starch synthesis also led to a decrease in the rate of (14)C-Suc degradation and its further metabolism via other metabolic pathways. This was not accompanied by an increase in the levels of soluble sugars, indicating that Suc import was inhibited in parallel. Flux through glycolysis, the activities of hexokinase, and inorganic pyrophosphate-dependent phosphofructokinase, and the adenylate energy state (ATP to ADP ratio) of the transgenic seeds decreased, indicating inhibition of glycolysis and respiration compared to wild type. This was accompanied by a marked decrease in the rate of storage lipid (triacylglycerol) synthesis and in the fatty acid content of seeds. In mature seeds, glycolytic enzyme activities, metabolite levels, and ATP levels remained unchanged, and the fatty acid content was only marginally lower compared to wild type, indicating that the influence of AGPase on carbon metabolism and oil accumulation was largely compensated for in the later stages of seed development. Results indicate that AGPase exerts high control over starch synthesis at early stages of seed development where it is involved in establishing the sink activity of the embryo and the onset of oil accumulation.
