The paper develops a combined modeling framework for forecasting future CO2 emissions in China, the United States, the European Union, India, and Japan using a background value optimized Nonlinear Grey Bernoulli model integrated with a BP neural network. It optimizes PSO via an Artificial Fish Swarm Algorithm idea, dynamically tunes the ONGBM(1,1) background value, derives a time response function via model linearization, and determines the combination weight and background value coefficient using the improved PSO. Using observed data from 2010–2021 from the Emissions Database for Global Atmospheric Research 2022, it forecasts 2022–2026 and reports that the new BP-ONGBM(1,1) model performs significantly better than several competitive models, though the abstract does not specify quantitative metrics or modeling assumptions beyond the stated approach. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

A new Nonlinear Grey Bernoulli and BP neural network combined model (BP-ONGBM (1,1) model) has been proposed to study the CO 2 emissions of China, the United States, the European Union, India and Japan. Firstly, the Particle Swarm Optimization (PSO) algorithm is optimized by using the idea of Artificial Fish Swarm Algorithm (AFSA), and then the background value of ONGBM (1,1) model is dynamically optimized. Based on the linearization of the model, the time response function is derived. Then, the ONGBM (1,1) model is combined with the BP neural network model. The combination weight and the background value coefficient are determined by improved PSO algorithm. Finally, according to the observation data from 2010 to 2021 in the Emissions Database for Global Atmospheric Research 2022, the model is established to calculate the CO 2 emissions of the selected countries from 2022 to 2026, and compared with the prediction results provided by multiple competitive models. The empirical application shows that the newly proposed BP-ONGBM (1,1) model is significantly better than other competitive models.
