The accurate prediction of air pollutants, particularly Particulate Matter (PM), is critical to support effective and persuasive air quality management. Numerous variables influence the prediction of PM, and it's crucial to combine the most relevant input variables to ensure the most dependable predictions. This study aims to address this issue by utilizing correlation coefficients to select the most pertinent input and output variables for an air pollution model. In this work, PM2.5 concentration is estimated by employing concentrations of sulfur dioxide, nitrogen dioxide, and PM10 found in the air through the application of Artificial Neural Networks (ANNs). The proposed approach involves the comparison of three ANN models: one trained with the Levenberg–Marquardt algorithm (LM-ANN), another with the Bayesian Regularization algorithm (BR-ANN), and a third with the Scaled Conjugate Gradient algorithm (SCG-ANN). The findings revealed that the LM-ANN model outperforms the other two models and even surpasses the Multiple Linear Regression method. The LM-ANN model yields a higher R2 value of 0.8164 and a lower RMSE value of 9.5223.

आज #वाराणसी #Varanasi का जन्मदिन है। आज ही शहर का आधिकारिक नाम 'वाराणसी' स्वीकृत किया गया था। इस शहर के नाम की देवी भी हैं जिनको "वाराणसी देवी" कहा जाता है। मंदिर त्रिलोचन घाट के त्रिलोचन मंदिर में स्थित है। @alaknanda_kashi @ShriVishwanath @Varanasi_DM @narendramodi @kashikirai https://t.co/YQUor5RMCm
