How a General-Purpose Commonsense Ontology can Improve Performance of Learning-Based Image Retrieval
The knowledge representation community has built general-purpose ontologies
which contain large amounts of commonsense knowledge over relevant aspects of
the world, including useful visual information, e.g.: "a ball is used by a
football player", "a tennis player is located at a tennis court". Current
state-of-the-art approaches for visual recognition do not exploit these
rule-based knowledge sources. Instead, they learn recognition models directly
from training examples. In this paper, we study how general-purpose
ontologies---specifically, MIT's ConceptNet ontology---can improve the
performance of state-of-the-art vision systems. As a testbed, we tackle the
problem of sentence-based image retrieval. Our retrieval approach incorporates
knowledge from ConceptNet on top of a large pool of object detectors derived
from a deep learning technique. In our experiments, we show that ConceptNet can
improve performance on a common benchmark dataset. Key to our performance is
the use of the ESPGAME dataset to select visually relevant relations from
ConceptNet. Consequently, a main conclusion of this work is that
general-purpose commonsense ontologies improve performance on visual reasoning
tasks when properly filtered to select meaningful visual relations.Comment: Accepted in IJCAI-1
Programming distributed and adaptable autonomous components--the GCM/ProActive framework
International audienceComponent-oriented software has become a useful tool to build larger and more complex systems by describing the application in terms of encapsulated, loosely coupled entities called components. At the same time, asynchronous programming patterns allow for the development of efficient distributed applications. While several component models and frameworks have been proposed, most of them tightly integrate the component model with the middleware they run upon. This intertwining is generally implicit and not discussed, leading to entangled, hard to maintain code. This article describes our efforts in the development of the GCM/ProActive framework for providing distributed and adaptable autonomous components. GCM/ProActive integrates a component model designed for execution on large-scale environments, with a programming model based on active objects allowing a high degree of distribution and concurrency. This new integrated model provides a more powerful development, composition, and execution environment than other distributed component frameworks. We illustrate that GCM/ProActive is particularly adapted to the programming of autonomic component systems, and to the integration into a service-oriented environment
Towards Grid Monitoring and deployment in Jade, using ProActive
This document describes our current effort to gridify Jade, a java-based
environment for the autonomic management of clustered J2EE application servers,
developed in the INRIA SARDES research team. Towards this objective, we use the
java ProActive grid technology. We first present some of the challenges to turn
such an autonomic management system initially dedicated to distributed
applications running on clusters of machines, into one that can provide
self-management capabilities to large-scale systems, i.e. deployed on grid
infrastructures. This leads us to a brief state of the art on grid monitoring
systems. Then, we recall the architecture of Jade, and consequently propose to
reorganize it in a potentially more scalable way. Practical experiments pertain
to the use of the grid deployment feature offered by ProActive to easily
conduct the deployment of the Jade system or its revised version on any sort of
grid
Flexible adaptation loop for component-based soa applications
Best paperInternational audienceThe Service Oriented Architecture (SOA) modelfosters dynamic interactions of heteregeneous and loosely-coupled service providers and consumers. Specifications likethe Service Component Architecture (SCA) have been used totackle the complexity of developing such dynamic applications;however, concerns like runtime management and adaptationare often left as platform specific matters. At the same time,runtime QoS requirements stated in Service Level Agreements(SLA) may also evolve at runtime, and not only the appli-cation needs to adapt to them, but also the monitoring andmanagement tasks. This work presents a component basedframework that provides flexible monitoring and managementtasks and allows to introduce adaptivity to component-basedSOA applications. The framework implements each phase ofthe autonomic control loop as a separate component, and allowsmultiple implementations on each phase, giving enough run-time flexibility to support evolving non functional requirementson the application. We present an illustrative scenario thatis dynamically augmented with components to tackle non-functional concerns and support adaptation as it is needed.We use an SCA compliant platform that allows distributionand architectural reconfiguration of component
Management of service composition based on self-controlled components
International audienceCloud computing and Future Internet promise a new ecosystem where everything is "as a service", reachable and connectable anywhere and anytime, everyone succeeding to get a service composition that meets his needs. But do we have the structure and the appropriate properties to design the service components and do we have the means to manage, at run-time, the personalised compositions corresponding to Service Level Agreement? In this article we introduce an entity of service composition called Self-Controlled Component (SCC), including, since the design step, functional and non-functional specifications. SCCs benefit both from the strong structure, explicit composition, and autonomic management of component-oriented programming, from the highly dynamic composition, and from the discovery capacities of service-oriented computing. Self-control mechanisms are then attached automatically to SCCs to enable autonomic application management during execution. The objective of this new concept is to provide strong Quality of Service (QoS) guarantees of composed applications. We illustrate the approach using an example called Springoo, to how in the context of a legacy application the contributions and benefits of our solution. For the management of the service composition we propose the concept of Virtual Private Service Network (VPSN) and Virtual Service Community (VSC) that allows us to model the personalised Service Level Agreement (SLA) where user requirements and provider offers converge on a QoS contract

Luego de la realización de un análisis FODA en la Escuela Carlos Spano de Talca detectamos un alto porcentaje de estudiantes con Necesidades Educativas Especiales (de ahora en adelante también llamadas NEE), por lo que decidimos investigar acerca de las metodologías de inclusión utilizadas en el 6to año básico B dado que este curso integrado por 18 estudiantes presenta un alto número de estudiantes con NEE. La Escuela Carlos Spano cuenta con un Programa de Integración Escolar (de ahora en adelante también mencionado como PIE) que se rige bajo la Ley de Inclusión Escolar de Chile n°20.845, la que decreta un número de 7 estudiantes por curso acogidos por éste, 2 en modalidad permanente y 5 en transitoria. El objetivo principal de esta investigación es identificar las metodologías de inclusión utilizadas en el 6to año básico B de la Escuela Carlos Spano de Talca, estos mismos forman parte de la comunidad estudiada, además de los docentes del área de matemáticas, lenguaje y música. Los instrumentos de investigación aplicados para obtener los datos a analizar durante este trabajo de grado fueron: entrevistas a profesores ya antes mencionados, entrevistas a funcionarias del PIE, listas de observación de clases y encuestas a los estudiantes pertenecientes al curso observado. En las conclusiones podremos ver el resultado de la implementación de metodologías utilizadas en el 6to año básico B de la Escuela Carlos Spano de Talca, tanto por el PIE como por el establecimiento, viéndose reflejado en el sentir de los/as estudiantes en el ámbito escolar
Case report: Efficacy of immunotherapy as conversion therapy in dMMR/MSI-H colorectal cancer: a case series and review of the literature
Immunotherapy has demonstrated a role in the therapeutic landscape of a small subset of patients with colorectal carcinoma (CRC) that harbor a microsatellite instability (MSI-H) status due to a deficient DNA mismatch repair (dMMR) system. The remarkable responses to immune checkpoint inhibitors (ICIs) are now being tested in the neoadjuvant setting in localized CRC, where the dMMR/MSI-H status can be found in up to 15% of patients, with remarkable results obtained in NICHE2 and 3 trials, among others. This case series aims to report our experience at a tertiary center and provide a comprehensive analysis of the possible questions and challenges to overcome if ICIs were established as standard of care in a neoadjuvant setting, as well as the potential role they may have as conversion therapy not only in locoregional advanced CRC but also in oligometastatic disease
First results of the CAST-RADES haloscope search for axions at 34.67 μeV
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67μeV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. An exclusion limit with a 95% credibility level on the axion-photon coupling constant of gaγ & 4 × 10−13 GeV−1 over a mass range of 34.6738μeV < ma < 34.6771μeV is set. This constitutes a significant improvement over the current strongest limit set by CAST at this mass and is at the same time one of the most sensitive direct searches for an axion dark matter candidate above the mass of 25μeV. The results also demonstrate the feasibility of exploring a wider mass range around the value probed by CAST-RADES in this work using similar coherent resonant cavitiesWe wish to thank our colleagues at CERN, in particular Marc Thiebert from the coating lab, as well as the whole team of the CERN Central Cryogenic Laboratory for their support and advice in speci c aspects of the project.
