Prediction of 3‐month treatment outcome of IgG4‐DS based on BP artificial neural network

Abstract

Objective The study aimed to establish an effective back‐Propagation artificial neural network (BP‐ANN) model for automatic prediction of 3‐month treatment outcome of IgG4‐DS. Methods A total of 26 IgG4‐DS patients at Shanghai Ninth People's Hospital from January 2018 to December 2019 were involved in the study. They were all followed for >3 months. The primary outcome was reduction of serum IgG4 (sIgG4) after 3‐month treatment. The association between risk factors and reduction of sIgG4 was analyzed by Spearman's rank correlation test. According to the R values, we built a BP‐ANN model by MATLAB R2019b. Results The average reduction of sIgG4 was 5.55 ± 5.03. After Spearman's rank correlation test, ESR, sIgG4, and sIgG were independently associated with reduction of sIgG4 (p < .05) and were selected as input variables. Take into account these parameters, BP‐ANN model was developed and the coefficient of determination (R2) model was 0.95512. Conclusion The BP‐ANN model based on ESR, sIgG4, and sIgG could predict the 3‐month reduction of sIgG4 for IgG4‐DS patients. It showed potential clinical application value.

[Retracted] Sports Action Recognition Based on GB‐BP Neural Network and Big Data Analysis

“…On the other hand, the fuzzy controller can be used to approximate the control algorithm, so as to realize the automatic classification of actions. It is necessary to divide the wrestlers' daily sports training data information into multiple levels and effectively process it according to the intelligent algorithm [ 23 ]. According to different reference standards, we classify the classification rules of wrestlers' training action recognition and decision-making model.…”

Application of Improved BP Neural Network in the Optimization of Regional Economic Energy Consumption Structure

“…Although this method can effectively improve the utilization of differ-ent types of data, there are still many deficiencies. For example, it is unable to realize the best matching analysis of energy consumption related to different types of enterprises according to the requirements of regional economic energy consumption [4]. Based on this, this paper proposes an optimization analysis model of regional economic energy consumption structure based on the improved BP neural network algorithm.…”

Prevalence of depressive symptoms and associated factors during the COVID-19 pandemic: A national-based study

“…According to previous studies, BPNN has a better prediction function than multiple logistic regression models in complex model fitting and distribution approximation ( Kulkarni et al, 2021 ; Schmidhuber, 2015 ). BPNNs have been widely used in the fields of clinical medicine, computer science, engineering and so on ( Ning et al, 2021 ; Shao et al, 2021 ; Zheng, 2021 ). However, very few examples of the application of BPNN are available in previous research in the field of mental health ( Fan et al, 2021 ; J. Lv et al, 2022 ).…”
