Fidalgo, André Filipe dos Santos Pinto. "IPTV data reduction strategy to measure real users’ behaviours". Master's thesis, Faculdade de Ciências e Tecnologia, 2012. http://hdl.handle.net/10362/8448.
Pełny tekst źródłaThe digital IPTV service has evolved in terms of features, technology and accessibility of their contents. However, the rapid evolution of features and services has brought a more complex offering to customers, which often are not enjoyed or even perceived. Therefore, it is important to measure the real advantage of those features and understand how they are used by customers. In this work, we present a strategy that deals directly with the real IPTV data, which result from the interaction actions with the set-top boxes by customers. But this data has a very low granularity level, which is complex and difficult to interpret. The approach is to transform the clicking actions to a more conceptual and representative level of the running activities. Furthermore, there is a significant reduction in the data cardinality, enhanced in terms of information quality. More than a transformation, this approach aims to be iterative, where at each level, we achieve a more accurate information, in order to characterize a particular behaviour. As experimental results, we present some application areas regarding the main offered features in this digital service. In particular, is made a study about zapping behaviour, and also an evaluation about DVR service usage. It is also discussed the possibility to integrate the strategy devised in a particular carrier, aiming to analyse the consumption rate of their services, in order to adjust them to customer real usage profile, and also to study the feasibility of new services introduction.

Pełny tekst źródłaAn artificial neural network (ANN) for use in real time data reduction and analysis will be presented. The use and advantage of hardware and software implementations of neural networks will be considered. The ability of neural networks to learn and store associations between different sets of data can be used to create custom algorithms for some of the data analysis done during missions. Once trained, the ANN can distill the signals from several sensors into a single output, such as safe/unsafe. Used on a neural chip, the trained ANN can eliminate the need for A/D conversions and multiplexing for processing of combined parameters and the massively parallel nature of the network allows the processing time to remain independent of the number of parameters. As a software routine, the advantages of using an ANN over conventional algorithms include the ease of use for engineers, and the ability to handle nonlinear, noisy and imperfect data. This paper will apply the ANN to performance data from a T-38 aircraft.

Pełny tekst źródłaData acquisition for flight test is typically handled by dedicated hardware which performs specific functions and targets specific interfaces and buses. Through the use of an FPGA state machine based design approach, performance and robustness can be guaranteed. Up to now sufficient flexibility has been provided by allowing the user to configure the hardware depending on the particular application. However by allowing custom algorithms to be run on the data acquisition hardware, far greater control and flexibility can be offered to the flight test engineer. As the volume of the acquired data increases, this extra control can be used to vastly reduce the amount of data to be recorded or telemetered. Also real-time analysis of test points can now be done where post processing would previously have been required. This paper examines examples of data acquisition, recording and processing and investigates where data reduction and time savings can be achieved by enabling the flight test engineer to run his own algorithms on the hardware.

Pełny tekst źródłaEsta tesis establece las bases de FADRA: Framework for Astronomical Data Reduction and Analysis. El framework FADRA fue diseñado para ser eficiente, simple de usar, modular, expandible, y open source. Hoy en día, la astronomía es inseparable de la computación, pero algunos de los software más usados en la actualidad fueron desarrollados tres décadas atrás y no están diseñados para enfrentar los actuales paradigmas de big data. El mundo del software astronómico debe evolucionar no solo hacia prácticas que comprendan y adopten la era del big data, sino también que estén enfocadas en el trabajo colaborativo de la comunidad. El trabajo desarollado consistió en el diseño e implementación de los algoritmos básicos para el análisis de datos astronómicos, dando inicio al desarrollo del framework. Esto consideró la implementación de estructuras de datos eficientes al trabajar con un gran número de imágenes, la implementación de algoritmos para el proceso de calibración o reducción de imágenes astronómicas, y el diseño y desarrollo de algoritmos para el cálculo de fotometría y la obtención de curvas de luz. Tanto los algoritmos de reducción como de obtención de curvas de luz fueron implementados en versiones CPU y GPU. Para las implementaciones en GPU, se diseñaron algoritmos que minimizan la cantidad de datos a ser procesados de manera de reducir la transferencia de datos entre CPU y GPU, proceso lento que muchas veces eclipsa las ganancias en tiempo de ejecución que se pueden obtener gracias a la paralelización. A pesar de que FADRA fue diseñado con la idea de utilizar sus algoritmos dentro de scripts, un módulo wrapper para interactuar a través de interfaces gráficas también fue implementado. Una de las principales metas de esta tesis consistió en la validación de los resultados obtenidos con FADRA. Para esto, resultados de la reducción y curvas de luz fueron comparados con resultados de AstroPy, paquete de Python con distintas utilidades para astrónomos. Los experimentos se realizaron sobre seis datasets de imágenes astronómicas reales. En el caso de reducción de imágenes astronómicas, el Normalized Root Mean Squared Error (NRMSE) fue utilizado como métrica de similaridad entre las imágenes. Para las curvas de luz, se probó que las formas de las curvas eran iguales a través de la determinación de offsets constantes entre los valores numéricos de cada uno de los puntos pertenecientes a las distintas curvas. En términos de la validez de los resultados, tanto la reducción como la obtención de curvas de luz, en sus implementaciones CPU y GPU, generaron resultados correctos al ser comparados con los de AstroPy, lo que significa que los desarrollos y aproximaciones diseñados para FADRA otorgan resultados que pueden ser utilizados con seguridad para el análisis científico de imágenes astronómicas. En términos de tiempos de ejecución, la naturaleza intensiva en uso de datos propia del proceso de reducción hace que la versión GPU sea incluso más lenta que la versión CPU. Sin embargo, en el caso de la obtención de curvas de luz, el algoritmo GPU presenta una disminución importante en tiempo de ejecución comparado con su contraparte en CPU.

Pełny tekst źródłaL'objectif principal de ce projet de doctorat est d'analyser la dépendance temporelle de l’ADF. Cette dépendance se produit, par exemple, si les données sont constituées à partir d'un processus en temps continu qui a été découpé en segments, les jours par exemple. Nous sommes alors dans le cadre des séries temporelles fonctionnelles.
La première partie de la thèse concerne la régression linéaire fonctionnelle, une extension de la régression multivariée. Nous avons découvert une méthode, basé sur les données, pour choisir la dimension de l’estimateur. Contrairement aux résultats existants, cette méthode n’exige pas d'assomptions invérifiables.
Dans la deuxième partie, on analyse les modèles linéaires fonctionnels dynamiques (MLFD), afin d'étendre les modèles linéaires, déjà reconnu, dans un cadre de la dépendance temporelle. Nous obtenons des estimateurs et des tests statistiques par des méthodes d’analyse harmonique. Nous nous inspirons par des idées de Brillinger qui a étudié ces models dans un contexte d’espaces vectoriels.
