für 71.91€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book is mainly about the evaluation of adaptive recommender systems. Recommendation is the action, for an intelligent system, to supply a user of an app with personalized content so as to enhance what is referred to as `user experience` e.g. recommending a product on a merchant website or an article on a blog. Many applications that are of interest to us generate a huge amount of data through their millions of online users. Nevertheless, using this data to evaluate a new recommendation technique, and in particular one that learns online (adaptive) is far from trivial. Some approaches have been proposed but they were not studied thoroughly both from a theoretical point of view and from an empirical one. In this work we start by filling blanks within the theoretical analysis. Then we comment on the results of an experiment of unprecedented scale in this area: a public challenge we organized. This challenge along with some complementary experiments revealed an unexpected and tremendous source of bias: time acceleration. The rest of this work tackles this issue. We show that a bootstrap-based approach allows to significantly reduce this bias and more importantly to control it. ····· 103614763

Cependant, l`initialisation et l`observation d`un modèle de SES sont devenues difficiles à mettre en oeuvre. Toutefois, aucun cadre générique n`a été développé pour résoudre ce problème. L`objectif de cet ouvrage est de proposer un cadre générique de spécification de l`initialisation et de l`observation des modèles de SES afin d`engendrer facilement les indicateurs que les thématiciens veulent suivre pendant la simulation. Pour cela, nous proposons de reformuler l`initialisation et l`observation de modèle en un problème de transformation entre structures de données. Cette reformulation permet d`utiliser les concepts de l`ingénierie dirigée par les modèles (IDM) afin de mettre en oeuvre des langages dédiés (DSL). Ces derniers fournissent les concepts nécessaires permettant aux thématiciens de spécifier plus facilement l`initialisation et l`observation de modèles de SES. ····· 103614645

De telles exigences ont conduit au développement des systèmes décisionnels. On s`intéressera au contexte dans lequel sont apparus les systèmes décisionnels, ainsi qu`à l`architecture autour de laquelle ils sont construits, en détaillant chacun de ses composants. Cette architecture s`appuie sur un espace de stockage centralisé : l`entrepôt de données dont la mise en place peut se faire selon diverses approches (de haut en bas, de bas en haut ou hybride). L`entrepôt de données va être alimenté au travers d`un processus ETL pour finalement présenter des données prêtes à l`exploitation grâce aux outils dédiés. Nous présenterons les travaux de recherches liés aux entrepôts qui traitent notamment de la maintenance et de la configuration des vues matérialisées.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Gradient based methods are one of the most widely used error minimization methods used to train back propagation networks. The BP training algorithm is a supervised learning method for multi-layered feedforward neural networks. It is essentially a gradient descent local optimization technique which involves backward error correction of the network weights. It has many limitations of convergence , getting trapped in local minima and performance. To solve this there are different modifications like introducing momentum and bias terms, conjugate gradient are used. In the conjugate gradient algorithms a search is performed along conjugate directions, which produces generally faster convergence than steepest descent directions.Here, in this monograph we will consider parity bit checking problem with conventional backpropagation method and other methods. We have to construct suitable neural network and train it properly. The training dataset has to be used to train classification engine for solution purpose and then the trained network is used for testing its validation. ····· 103613833

It is transformed from static information to dynamic pages and the future of web is service oriented. Service providers started publishing services on the web and the service requestors are querying these services. Number of services published on the internet is increasing rapidly. Finding valuable and attractive web services are becoming difficult due to massive number of services. Requirement of web services mining like data mining is vital nowadays. In this paper we have presented a comparative study of web services compositions with mining concepts. We proposed a web services mining frame work based on fuzzy logic, fuzzy set theory and fuzzy matching algorithm. This framework helps us in finding valuable services and composing those services into composite web services. Mined services are further filtered in the constraint satisfaction and evaluation phases where specified constraints are matched. Framework is tested with different UDDI registries of large sizes and the results are compared with existing techniques. ····· 103613753
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Real time distributed systems (RTDS) operate in an environment that un- dergoes unpredictable changes causing certain system performance features to degrade. Such unpredictability can be the result of sudden machine failures, in- creases in system load, or errors caused by inaccurate initial estimation. These systems need robustness to guarantee limited degradation despite uctuations in the behavior of its component parts or environment. The robustness gives an idea of the stability of the solution with regards to another performance metric such as schedule length, load balance of an application, queue waiting time of batch scheduler, etc. Designing robust systems for such environments involves determining resource allocations that can account for uncertainty in estimated system parameters. Robustness of the system can be achieved with proper resource allocation. ····· 103613743
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Nowadays, digital images are used in many areas in everyday life, but they tend to be big. This increment of the amount of information leads us to the problem of image data storage. An important feature of image compression is that it can be lossy or lossless. A compressed image is acceptable provided these losses of image information are not perceived by the eye. It is possible to assume that a portion of this information is redundant. In lossy compression, current image compression schemes remove information considered irrelevant by using mathematical criteria. One of the problems of these schemes is that although the numerical quality of the compressed image is low, it shows a high visual image quality, e.g. it does not show a lot of visible artifacts. It is because these mathematical criteria, used to remove information, do not take into account if the viewed information is perceived by the Human Visual System. Therefore, the aim of the PHi-SET image compression scheme is for obtaining images that do not show artifacts although their numerical quality is low, eliminating information that is not vosible by the Human Visual System. ····· 103613687
für 69.21€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The idea of Software Product Line (SPL) approach is to manage a family of similar software products in a reuse-based way. Reuse avoids repetitions, which helps reduce development/maintenance effort, shorten time-to-market and improve overall quality of software. A number of open problems must be solved for SPL to have wide-spread impact on software practice. One of them is to understand and manage variability in software artefacts. To migrate from existing software products into SPL, one has to understand how they are similar and how they differ one from another. In this book, We propose higher level of automation, and a sandwich approach that consolidates feature knowledge from top-down domain analysis with bottom-up analysis of code similarities in subject software products. Our proposed method integrates model differencing, software clone detection, and information retrieval techniques, which can provide a systematic means to reengineer the legacy software products into SPL based on automatic variability analysis. Finally, the benefits and trade-offs involved in strategies of software variability management are discussed. ····· 103613649

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The wide usage of computers to keep records systematically has led to a number of different-specific databases to be developed, which is one of the persistent problems the database and information management communities have to deal with. These great number of databases created, has resulted into incompatibility among databases. Thus,this work proposes an approach in solving the problem of interoperability between heterogeneous databases through the alignment of heterogeneous databases. This can be accomplished by determining one to one mapping between database elements, and thereafter reformulates the query in such a way that will be compatible to different database platforms involved. In this regard, this work provides a framework for integrated heterogeneous database using schema matching as an approach, which can be used to reconcile heterogeneous database systems and further enhance automatic interoperability among database systems.The interoperability between databases will be supported without modifying the database or loosing their autonomy. ····· 103613586
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Acquisition of 3D model of real objects and scenes is indispensable and useful in many practical applications, such as digital archives, game and entertainment industries, engineering, advertisement. However, a single photograph, while records the color, the brightness of one scene, can not provide its 3D structure. Fortunately, with many photographs of the scene in different viewpoints, the 3D information can be revealed with a technique called multi-view stereo. This image-based technique is easier, cheaper, faster than the active range finding technique (laser-based technique), especially for large-scale outdoor scenes. Nevertheless, one disadvantage of the multi-view technique comparing to the laser-based technique is its lack of accuracy. In this work, we target the accuracy as well as scalability issues. We significantly improve some previous multi-view methods and combine them into a remarkably effective pipeline with GPU acceleration. We produce highly complete and accurate meshes that achieve best scores in many benchmarks. Then, we develop Divide and Conquer, mesh merging methods in order to build large 3D models from thousands of high-resolution images. ····· 103613537
