基于深度感知增量式联想记忆神经网络的信息融合系统研究

Information fusion of multi-sensing channels is one of the basic functions of the human brain. The integration of many basic sensing channels such as vision and hearing through the brain's synesthetic area can increase the accuracy of perception. The information fusion technologies simulating this ability of human brain have a wide range of applications in many fields such as artificial intelligence, medical treatment and military weaponry. This project will simulate the human brain's information fusion mechanism and construct an information fusion intelligent system. In view of the shortcomings of current information fusion systems such as multi-channel deep perception, the fusion of abstractive patterns in heterogeneous channels, incremental learning of new targets, and incremental expansion of new perceptual channels, this project will study the multi-channel associative memory neural network and apply it to the information fusion system. The information fusion system designed by this project will be capable of acquiring and expressing multi-channel perceptive information, adapting to dynamic environments and incremental learning, associative memorizing multi-channel information, recognizing and understanding targets in environments. The research results of this project would promote the development of theories and technologies in the fields of brain-like computing and neural networks. This project is also important for understanding the human brain mechanism, the development of artificial intelligence and various types of AI applications.
