Evaluation of SEO based on neural network-Introduction of neural network (1)

The basic concept of neural network &http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;"

The development of artificial Neural networks (Ann) can be traced back to a century ago. In recent years, it has developed into a very popular interdisciplinary. It involves the disciplines of biology, electronics, computer, mathematics and physics, using physically achievable devices or existing computers to simulate certain structures and functions of neural networks in organisms, and to make them available in engineering or other fields. The focus of the artificial neural network is not to use physical devices to replicate the neural network in the organism, but to adopt its available parts to overcome problems that cannot or cannot be solved by computers or other systems, such as automatic learning, pattern recognition, intelligent control, and expert system. With the development of biology and cognitive science, people's understanding of the structure of human brain and understanding of the process of further in-depth, artificial neural network technology development and application will have a broader prospect.

In the Internet application, artificial neural network also has a more successful application, especially for some difficult to describe the logic relationship between information, and in the absence of expert experience, Ann can often find a more satisfactory answer. But generally speaking, the application of Ann is still in the initial stage, in order to really enter the use stage, there is still a lot of work to do.

For a long time, humans have sought to understand the function of the human brain, to imitate the human brain with a physical and achievable system, to accomplish a task similar to that of the human brain. From the structure of the human brain, the human brain is a combination of a large number of nerve cells, each cell to complete a certain two basic functions, but at the same time these cells with each other to complete the brain complex thinking, memory and other functions.

Neural network applications in the Internet is not much, just started, no one has been applied to the SEO.
