Data Dependency Graph

Spark is a cluster computing platform that originated at the University of California, Berkeley Amplab. It is based on memory calculation, from many iterations of batch processing, eclectic data warehouse, flow processing and graph calculation and other computational paradigm, is a rare all-round player. Spark has formally applied to join the Apache incubator, from the "Spark" of the laboratory "" EDM into a large data technology platform for the emergence of the new sharp. This article mainly narrates the design thought of Spark. Spark, as its name shows, is an uncommon "flash" of large data. The specific characteristics are summarized as "light, fast ...

Baidu and the Drug Administration recently reached a strategic cooperation, Baidu will make the Drug Administration of drugs data for people to provide drug-related inquiries. The price that Baidu paid for the data was not mentioned. The world does not have a free lunch, although the FDA is for the benefit of the people, but this batch of data is clearly not for nothing. That means the time has come for search engines to pay for the data. I would like to talk today about the search and data relationship of some views. 　　Note that the big data is too far away from us and this is not about big data. 360 and immediately before the strategic cooperation to jointly operate food safety and Exposure column column, and 36 ...

Information graphic Design (inforgraphic-design), a branch of information design (information-design), is a new type of visual design that arose at the end of the 20th century when information technology was involved in a variety of graphic design processes. Infographic is a composite system of readable visualization, which combines images, words and numbers to communicate information more efficiently. It helps people to better transform words through the visual element system of specific text content, notably, clearly, simply, directly, coherently and comprehensively.

Before introducing the microblogging recommendation algorithm, let's talk about recommendation systems and recommended algorithms. There are some questions: what scenarios does the recommendation system apply to? What are the problems and what value are they used to solve? How is the effect measured? The recommendation system was born very early, but was really valued by everyone, originated from the "Facebook" as the representative of the rise of social networks and "Taobao" as the representative of the prosperity of the electric business, "choice" of the era has come, information and items of great wealth, so that users such as the vast universe of small points, at a loss. The recommendation system ushered in an outbreak of opportunity to become closer to the user: fast ...

Spark is a rare all-round player, starting from multiple iterations, eclectic data Warehouse, stream processing and graph calculation. Spar ...

In January 2014, Aliyun opened up its ODPS service to open beta. In April 2014, all contestants of the Alibaba big data contest will commission and test the algorithm on the ODPS platform. In the same month, ODPS will also open more advanced functions into the open beta. InfoQ Chinese Station recently conducted an interview with Xu Changliang, the technical leader of the ODPS platform, and exchanged such topics as the vision, technology implementation and implementation difficulties of ODPS. InfoQ: Let's talk about the current situation of ODPS. What can this product do? Xu Changliang: ODPS is officially in 2011 ...

In the past few years, the innovative development of the open source world has elevated the productivity of Java™ developers to one level. Free tools, frameworks and solutions make up for once-scarce vacancies. The Apache CouchDB, which some people think is a WEB 2.0 database, is very promising. It's not difficult to master CouchDB, it's as simple as using a Web browser. This issue of Java open ...

Learning methods depending on the type of data, there are different ways to model a problem. In the field of machine learning or artificial intelligence, people first consider the way of learning algorithms. In the field of machine learning, there are several main ways of learning. 　　It is a good idea to classify the algorithm according to the learning style, so that people can choose the most suitable algorithm according to the input data to get the best results when modeling and algorithm selection. Supervised learning: Under supervised learning, input data is called "training data", each group training number ...

Machine learning algorithm spicy, for small white I, the scissors are still messy, and I sort out some of the pictures that help me quickly understand. Machine Learning algorithm Subdivision-1. Many algorithms are a class of algorithms, and some algorithms are extended from other algorithms-2. From two aspects-2.1 learning methods supervised learning Common application scenarios such as classification problems and regression problems common algorithms include logistic regression (logistic regression) and reverse-transmission neural networks (back propagation neural netw ...
