Upgrade your programming language to more effectively handle high-frequency data Machine Learning and Big Data with KDB+/Q offers quants, programmers and algorithmic traders a practical entry into the powerful but non-intuitive kdb+ database and q programming language. Ideally designed to handle the speed and volume of high-frequency financial data at sell- and buy-side institutions, these tools have become the de facto standard; this book provides the foundational knowledge practitioners need to work effectively with this rapidly-evolving approach to analytical trading. The discussion follows the natural progression of working strategy development to allow hands-on learning in a familiar sphere, illustrating the contrast of efficiency and capability between the q language and other programming approaches. Rather than an all-encompassing “bible”-type reference, this book is designed with a focus on real-world practicality ­to help you quickly get up to speed and become productive with the language. Understand why kdb+/q is the ideal solution for high-frequency data Delve into “meat” of q programming to solve practical economic problems Perform everyday operations including basic regressions, cointegration, volatility estimation, modelling and more Learn advanced techniques from market impact and microstructure analyses to machine learning techniques including neural networks The kdb+ database and its underlying programming language q offer unprecedented speed and capability. As trading algorithms and financial models grow ever more complex against the markets they seek to predict, they encompass an ever-larger swath of data ­– more variables, more metrics, more responsiveness and altogether more “moving parts.” Traditional programming languages are increasingly failing to accommodate the growing speed and volume of data, and lack the necessary flexibility that cutting-edge financial modelling demands. Machine Learning and Big Data with KDB+/Q opens up the technology and flattens the learning curve to help you quickly adopt a more effective set of tools.

Beim Verarbeiten großer Datenmengen (Big Data) ist der Zeitfaktor entscheidend. Durch das Tuning der Abläufe können diese extrem verkürzt werden. Herkömmliche Methoden liefern dabei schon gute Ergebnisse. Die hier zusätzlich dargestellten, innovativen Methoden haben Anwendern bereits hohe Kosten eingespart. Die Methoden sind an Oracle Datenbanken beispielhaft durchgeführt, können aber auf alle anderen Datenbankprogramme übertragen werden.

You have a mound of data front of you and a suite of computation tools at your disposal. Which parts of the data actually matter? Where is the insight hiding? If you're a data scientist trying to navigate the murky space between data and insight, this practical book shows you how to make sense of your data through high-level questions, well-defined data analysis tasks, and visualizations to clarify understanding and gain insights along the way.When incorporated into the process early and often, iterative visualization can help you refine the questions you ask of your data. Authors Danyel Fisher and Miriah Meyer provide detailed case studies that demonstrate how this process can evolve in the real world.You'll learn:The data counseling process for moving from general to more precise questions about your data, and arriving at a working visualizationThe role that visual representations play in data discoveryCommon visualization types by the tasks they fulfill and the data they useVisualization techniques that use multiple views and interaction to support analysis of large, complex data sets

Este é um livro sobre bancos de dados (BD)para todos os tipos de leitores: desde o leigo total em processamento de dados que tem curiosidade em saber o que são BD, o usuário que sabe usar um editor de textos e a internet e gostaria de conhecer os conceitos e as práticas de BD, até o projetista de BD que quer melhorar sua técnica, e o especialista em BD que gostaria de aprender os conceitos de sua área ou aprofundar seus conhecimentos sobre vários tópicos da mesma. É indicado também àquele que aprendeu a implementar BD'fazendo', pois poderá finalmente conhecer e compreender os conceitos envolvidos em sua atividade, provavelmente melhorando seus produtos. Pode servir de texto para cursos de BD tanto de nível técnico, como de graduação e de pós-graduação; objetivando essa finalidade, foram introduzidos inúmeros exercícios para os quais, propositadamente, não será disponibilizada a solução, pois isso prejudicaria o esforço pessoal e aprendizado dos alunos. Obviamente, os exercícios servem para o autodidata fazer algo com os conhecimentos adquiridos e testá-los.

Ces dernières années, les besoins relatifs au traitement des données ont évolué à un rythme soutenu. Les sites web aux millions d'utilisateurs (réseaux sociaux, plates-formes de diffusion de contenus) sont à l'origine de l'essor de la plus dynamique des familles de moteurs de données : le NoSQL. Une base de données optimisée pour le big data Parmi les bases de données NoSQL, celles orientées'graphes'connaissent un succès fulgurant du fait de leur souplesse et de leur évolutivité extrême. Ne reposant sur aucun schéma, un graphe peut accepter de nouveaux flux de données sans nécessiter d'interventions lourdes. A l'heure où les sociétés ont compris que la fusion de leurs silos de données (CRM, ERP, Web, etc.) est une condition sine qua non pour créer de la valeur (solutions d'intelligence prédictive, moteurs de recommandation), cette propriété du graphe se révèle essentielle. En considérant les relations entre objets comme des données de premier ordre, de nouvelles perspectives d'exploration et d'analyse apparaissent et favorisent la découverte d'informations inédites. L'absence de barrières logiques ouvre également la porte à des modalités d'exploitation de la donnée en profondeur, sans nuire aux performances. Installés depuis de nombreuses années au coeur des infrastructures des géants du Web (Google, Facebook, Linkedln), les graphes sont désormais accessibles au plus grand nombre grâce à l'émergence des moteurs de graphes et notamment au leader du domaine : Neo4j. Un ouvrage de référence sur Neo4j Le présent ouvrage s'adresse à tous les publics confrontés au volet data d'un projet informatique : développeurs, DSI, directeurs techniques, chefs de projets, data miners et data scientists. Son objectif majeur est de vous aider à identifier les projets informatiques qui gagneront à mettre en oeuvre un graphe. Après une introduction au concept de graphe et une présentation de Neo4j et de son langage de requête (Cypher), le présent ouvrage illustre à l'aide d'exemples concrets la puissance des graphes pour traiter des problèmes aussi pointus que la recommandation et l'analyse de réseaux sociaux. Les grandes étapes d'un projet data-driven reposant sur le graphe sont illustrées de la conception à la mise en place de modèles prédictifs, en passant par l'ingestion des données et l'analyse. À qui s'adresse cet ouvrage? Aux administrateurs de bases NoSQL de type graphe. Aux développeurs et architectes, pour mettre en pratique les concepts avec Neo4j. Aux data scientists qui trouveront avec les graphes un outil complémentaire pour concevoir leurs modèles.

Episodes in the history of data, from early modern math problems to today's inescapable “dataveillance,” that demonstrate the dependence of data on culture.We live in the era of Big Data, with storage and transmission capacity measured not just in terabytes but in petabytes (where peta- denotes a quadrillion, or a thousand trillion). Data collection is constant and even insidious, with every click and every “like” stored somewhere for something. This book reminds us that data is anything but “raw,” that we shouldn't think of data as a natural resource but as a cultural one that needs to be generated, protected, and interpreted. The book's essays describe eight episodes in the history of data from the predigital to the digital. Together they address such issues as the ways that different kinds of data and different domains of inquiry are mutually defining; how data are variously “cooked” in the processes of their collection and use; and conflicts over what can—or can't—be “reduced” to data. Contributors discuss the intellectual history of data as a concept; describe early financial modeling and some unusual sources for astronomical data; discover the prehistory of the database in newspaper clippings and index cards; and consider contemporary “dataveillance” of our online habits as well as the complexity of scientific data curation.
