Psychology what is pattern recognition?

Pattern recognition is to study the automatic processing and interpretation of patterns by computers with mathematical techniques, and to collectively refer to environment and objects as "patterns". With the development of computer technology, it is possible for human beings to study the complex information processing process, and an important form of this process is the recognition of the environment and objects by organisms.

Pattern recognition focuses on image processing and computer vision, speech and language information processing, brain network group, brain-like intelligence and so on. And the mechanism and effective calculation method of human pattern recognition are studied.

Extended data:

The choice of pattern recognition method depends on the nature of the problem. If the recognized object is extremely complex and contains rich structural information, syntactic method is generally adopted; The recognized object is not very complex or contains no obvious structural information, so the decision theory method is generally adopted.

These two methods cannot be completely separated. In the syntactic method, the source language itself is extracted by decision theory. In application, combining these two methods and applying them to different levels can often get better results.

The rules of primitive combination pattern are specified by so-called grammar. Once the source language is recognized, the recognition process can be carried out through syntactic analysis, that is, whether a given pattern sentence conforms to the prescribed grammar or not, and those that conform to a certain grammar are classified into this category.
