The content of this article is PHP serialize serialized data and JSON formatted data analysis. if you need it, refer to PHP serialize to serialize variables, return a string expression with variable types and structures, while JSON is a lighter and more friendly format for interface (AJAX, REST, etc.) data exchange. In

processing programs, the requirements on the operating system are also important. Generally, servers must be used, in addition, the requirements for system security and stability are also relatively high. Especially for the operating system's own cache mechanism, temporary space processing and other issues need to be comprehensively considered. 15th, OLAP must be taken into account when using data warehou

Massive Data processing and analysis In my practical work, Dai ziliang, Beijing myisch Technology Co., Ltd., was lucky to have access to the massive data processing problem. It was an arduous and complex task to deal with it. The reasons are as follows: 1. If the data volume is too large, there may be any situation in

Course IntroductionR is a language and operating environment for statistical analysis, mapping, a free, free, open source software for the GNU system, an excellent tool for statistical computing and statistical mapping.The R language grammar is easy to understand and can easily learn and master the grammar of language. And after learning, we can develop our own functions to extend the existing language. Thi

computational performance cannot be used to solve the problem of specific data analysis. But by now, the different algorithms designed for specific business needs have been extremely rich and have greatly improved in performance and effectiveness. Computational Power -computing power is the last link in the era of big data, which can be said to be the last straw

Http://blog.csdn.net/DaiZiLiang/archive/2006/12/06/1432193.aspxIn my practical work, I have the honor to be exposed to the massive data processing problems. It is an arduous and complex task to process them. The reasons are as follows: 1. If the data volume is too large, there may be any situation in the data. If there are 10 pieces of

classified by one or two dimensions (ChiSquare1D. php and ChiSquare2D. php. My discussion will be limited to explaining how the ChiSquare1D. php class works and how to apply it to one-dimensional Web polls. Before proceeding, it should be noted that data is classified by two dimensions (for example, beer preferences are classified by gender ), you can start to describe your results by looking for system relationships or conditional probabilities in

describes how to call a web service. But as a series, considering that each person's focus is different, in order to make an overall introduction, we will also detail each step of the operation here. Through the third article, you can see how to use a client program to access the service interface and perform mining, prediction, and query to implement the product recommendation function. The fourth article is independent of the first three articles. It mainly introduces how to use Excel

. Before proceeding, it should be noted that data is classified by two dimensions (for example, beer preferences are classified by gender ), you can start to describe your results by looking for system relationships or conditional probabilities in a join table unit. Although many of the discussions below will help you understand the working principles of the ChiSquare2D. php software, other lab,

current scope. This is why big data is defined in 4 ways: Volume (volume), Variety (variety), Velocity (efficiency), and veracity (value), or 4V of big data. The following outlines each feature and the challenges it faces: 1. Volume Volume is talking about the amount of data a business has to capture, store, and access, producing 90% of all the world's

Data mining and analysis can be said to be the fastest-growing technology in the field of information, many different fields of experts have gained the space for development, making data mining become a hot topic of discussion in the business community.With the development of information technology, people collect data

First, prefaceBig Data technology has been going on for more than 10 years, from birth to the present. The market has long been a company or institutions, to the vast number of financial practitioners, "brainwashing" big data the future of good prospects and trends. With the user's deep understanding of big data concepts and technologies, people have begun to mov

many reconstruction methods, such as Voxel-based, 2D contour reconstruction methods, and so on, it is important to maintain the anatomical topological structure of the cortex.Brodmann's division is now widely used in the localization of the brain functional area, due to the specificity of the cortical structure, in addition to the primary motor and sensory cortex region is more constant, other functional areas and anatomical relationship between the variation is common, unless the nerve anatomy

The python language has been increasingly liked and used by program stakeholders in recent years, as it is not only easy to learn and master, but also has a wealth of third-party libraries and appropriate management tools; from the command line script to the GUI program, from B/S to C, from graphic technology to scientific computing, Software development to automated testing, from cloud computing to virtualization, all these areas have python, Python

The enterprise collects several terabytes of security-related data on a regular basis (such as network events, software application events, and personnel activity events) for compliance and postmortem forensics. It is estimated that the daily events of large enterprises of different sizes are between billions and billions. These values continue to grow as the enterprise enables more and more event logging s

mining algorithms, data modeling, and so on, as long as it is more than m of data, R is very difficult to do, But Python is basically competent. Add: Python has a dedicated data analysis package Pandas for SQL-like functions. However, Pandas loads all data into the memory.
