hij-1188	Gao, Zhenyu; Gong, Yaoben	Using PID-BP Digital Virtual Reality for Non-Heritage Protection: Recognition and Assessment	2025	15	.pdf	application/pdf	5828	327	40	To achieve this, we propose an improved method for the identification and assessment of non-heritage digital protection by optimizing the BP neural network using the PID search algorithm. The PID search algorithm is employed to optimize the BP neural network, which helps in establishing a mapping relationship between the feature vectors and the assessment values of non-heritage digital protection.	cache/hij-1188.pdf	txt/hij-1188.txt
