Derivation of BP neural network model and implementation of C language (reproduced)

bp neural network in BP for back propagation shorthand, the earliest it was by Rumelhart, McCelland and other scientists in 1986, Rumelhart and in nature published a very famous article "Learning R Epresentations by back-propagating errors ". With the migration of the Times, the theory of BP neural network has been improved and updated, which has undoubtedly beco

The AP and BP of a mobile phone can refer to both hardware and software in terms of context.1) Most phones contain two processors. Operating systems, user interfaces, and applications are performed on the application Processor (AP), with the AP generally using the arm chip's CPU. and the handset radio frequency communication control software, then runs on another separate CPU, this CPU is called baseband Processor (

A well-defined BP neural network explains, likes

Learning is one of the most important and compelling features of neural networks. In the development process of neural network, the study of learning algorithm has a very important position. At present, the neural network model proposed by people is corresponding to the learning algorithm. So, sometimes people don't ask for a strict definition or distinction between models and algorithms. Some models can have multiple algorithms. And some algorithms may be available for many models. However, som

Sybase accelerates the application development case of BP exploration

Working in a software environment that allows you to quickly create robust, flexible applications is the dream of every developer. SAIC, which runs the IT operations of BP Exploration, believes it has turned this dream into reality by combining Sybase's relational database management system with Sybase's PowerBuilder application development environment. Finding a suitable solution is a very difficult task. BP

BP neural Network--the realization of C language

Reprint: http://www.cnblogs.com/jzhlin/archive/2012/07/30/bp_c.html In the last article, we introduce the basic model of BP neural network, some terms in the model and the mathematical analysis of the model, and have a preliminary understanding of its principle. Then how to use the program language to specifically implement it, will be the next issue we need to discuss. This paper chooses the C language to realize a simple single hidden layer of
