The ACLPSO algorithm, based on dimension specification intervals, adaptively tunes maximum velocity, inertia weight, acceleration coefficient, and learning probability for each dimension. It has demonstrated excellent performance in benchmark function tests involving both single-modal and multi-modal functions. However, to obtain the global optimal or approximate optimal solutions for all executed benchmark functions, it is necessary to manually set appropriate values for the maximum velocity coefficient s and the learning probability coefficient v during the operation of the ACLPSO algorithm. This study introduces an automatic approach to assign values to s and v, relying on function iteration count and test function fitness convergence. This enhancement enables the improved ACLPSO algorithm to directly derive the global optimal or approximate optimal solutions for all benchmark functions, eliminating the need for manual parameter tuning.

Along with the progress of social civilization, human demand for production and life is also increasing. As a factor that affects people’s health all the time, the air environment has caused extensive research by scholars on the prediction of air environment quality. However, due to the different correlations of various factors affecting the prediction, the prediction results are affected. Thus, this study uses statistical methods to analyze the correlation of different factors in the prediction and uses the long-short-term memory network on basis of the attention mechanism to make predictions. Finally, we tested with the air data in Beijing and calculated that the accuracy of the model was 87.7%. The results show that the long-short-term memory network with the attention mechanism can accurately predict PM2.5, helping us to monitor and control air pollution better in cities.

In this paper, a design of air pollutant monitoring system with six modules based on Semi-supervised learning (SSL) is designed. More specifically, the data acquisition module, data pre-processing module, data classifier module, comprehensive analysis module, auxiliary sorting module, computer terminal module respectively realize data collection, dimension reduction pre-processing, classification, comprehensive analysis, sorting, observation and monitoring. After system operation, it perfectly realized the real-time monitoring and timely warning of haze pollution, and provided data support for the precision of urban air pollution prevention. The application of modern science and technology in air pollution monitoring has been realized, and the ability and level of air pollution prevention and control supervision have been improved. The experimental results show that the proposed system has higher accuracy monitoring of classification.
