Design for classification and recognition system of teenager mental health based on LM-BP algorithm

Abstract

In order to predict the psychological status of teenagers accurately and quickly and find their psychological problems in time, this paper proposes a BP neural network classification model based on LM algorithm. Compared with BP neural network of steepest descent algorithm, the LM algorithm has better convergence speed and accuracy in the inversion coefficient experiment. In the Chinese text sentiment analysis experiment, the Precision, Recall and F1 values of LM-BP were better than SD-BP. Based on LM-BP model, this paper presents a design scheme of teenagers mental health classification and recognition system. The scheme has good stability, availability and scalability, which lays a technical foundation for the implementation of the system.

SPCL: A Smart Access Control System That Supports Blockchain

“…This system utilizes blockchain to store addresses (instead of actual health data) to maintain privacy and efficiency, allowing nodes to securely access and share health data. More recently, Zhang et al [36] proposed a web3-based academic paper access control system for sharing papers. Due to the lack of blockchain support in current smart lock systems, SPCL provides a blockchain-enabled solution to provide safe and useful credentials for users using online hotel reservation systems.…”
