Abstract: The knowledge-acquisition mechanism generated from rough set and granular computing is integrated into Mind Evolution Algorithm（MEA）.The evolution direction is guided by the knowledge discovered from the data produced in the evolution process.As a result，the mind evolution algorithm under the guide of knowledge is realized，which reflects the knowledge abstraction and usage during human beings’ mind activities.The result of weight-value optimization of the neural network in multi-sensor information fusion system shows that this method is able to effectively improve the study efficiency and precision for neural networks.
