Abstract

The invention discloses a quantum neural network-based comprehensive evaluation method for a multi-factor system. The method comprises the following steps of: 1) setting a plurality of feed-forward quantum nerve cells of the multi-factor system; 2) preparing a quantum register of n quantum bits; 3) taking l 0) or l 1) of the quantum register as the input of factor number of a user receiver, and taking l phi> as the output of the factor number, wherein l phi> is equal to the sum of costheta l 0) and sintheta l 1) ; 4) setting a parallel computing operator O which is used for the output quantum state of the comprehensive evaluation method for the multi-factor system and is updated and evolved; and 5) till the updated output quantum state and the change before update are in a permitted error range, namely the network state is stable, determining that a sending information sequence corresponding to the output quantum state is the detection result of the multi-factor system.

Description

technical field [0001] The invention relates to the field of comprehensive evaluation of complex systems, in particular to a comprehensive evaluation method for multi-factor systems. Background technique [0002] The comprehensive evaluation methods commonly used in domestic and foreign transportation system evaluation can be generally divided into: expert evaluation method, economic analysis method, operations research method and other mathematical methods. Due to its characteristics of large-scale parallel processing, fault tolerance, self-organization and self-adaptive ability and associative function, neural network has become a powerful tool for solving problems. It has played a significant role and is widely used in many scientific fields. According to its characteristics, researchers also discussed the application of neural network model in comprehensive evaluation. [0003] As an important part of artificial intelligence, the neural network method can avoid the sub...
