Abstract: This paper first describes the basic principles of neutron spectrum unfolding. Subsequently, the application practice of intelligent algorithms in the field of neutron spectrum unfolding was discussed, covering two major directions: neural network algorithms and intelligent optimization algorithms. The former focuses on sorting out its evolutionary trajectory, gradually iterating from the early simple three-layer architecture to BP neural networks, generalized regression neural networks, and then to deep learning techniques; The latter introduces typical methods represented by genetic algorithm and particle swarm optimization algorithm. Furthermore, a brief introduction was given to the evaluation system and methods for the spectral performance of intelligent algorithms; Finally, combining the unique advantages of intelligent algorithms, the future development direction and potential in the field of neutron spectrum unfolding were discussed. The article aims to provide reference and inspiration for the in-depth research and practical application of intelligent spectral analysis methods.This paper first introduces the basic principles of neutron spectrum unfolding. Subsequently, the application of intelligent algorithms in this field is discussed, covering two major categories: neural network algorithms and intelligent optimization algorithms. For neural networks, the evolutionary trajectory is sorted out, which has gradually iterated from early simple three-layer architectures to Back Propagation (BP) neural networks, Generalized Regression Neural Networks (GRNN), and then to deep learning techniques. For intelligent optimization algorithms, typical methods represented by Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are introduced. Furthermore, the evaluation system and methods for the performance of intelligent algorithms are briefly summarized. Finally, based on the unique advantages of intelligent algorithms, this paper prospects the future development trends and potential in the field of neutron spectrum unfolding. This paper aims to provide references for the in-depth research and practical application of intelligent spectral analysis methods.
