In response to the problem of neglecting periodic and global characteristics sequence data when predicting PM2.5 concentrations via machine learning models, a prediction model based on feature space reconstruction multihead self-attention gated recurrent unit (FSR-MSAGRU) is proposed in this study. First, raw are subjected frequency spectrum analysis determine period value data. Subsequently, seasonal trend decomposition procedure loess (STL) employed capture periodicity information Then, reconstructed using data, decomposed components, residual components. Finally, input into (MSAGRU) with ability predict concentrations. Favorable results were attained by FSR-MSAGRU across 6 distinct experimental datasets, PCC exceeding 0.98 decrease accuracy metric SMAPE at least 68% compared that GRU model. Comparative 13 reference models demonstrate exhibits better performances stronger generalization abilities.
