Abstract	Ovaj rad fokusira se na unapređenje predikcije dnevnih koncentracija čestica u zraku na urbanim mjernim mjestima korištenjem konvolucijskih neuronskih mreža (CNN). Predviđeno je da 1D CNN, u usporedbi s algoritmima poput Random Forests, ima veću moć predviđanja. Podaci za predikciju oblikovani su kao vremenske multivarijatne vremenske serije. Analiza podataka provodila se korištenjem Pythona i MATLAB-a, dok je testiranje parametara modela izvedeno u Pythonu kako bi se identificirali optimalni parametri i stvorio što precizniji model. Rezultati pokazuju da je CNN model nadmašio performanse drugih modela, izraženo kroz koeficijente determinacije i apsolutne pogreške. Prikazuje se kako se predviđanja CNN modela usklađuju s stvarnim podacima, a svi modeli ukazuju na mogućnosti dodatne optimizacije. Daljnja analiza koncentracije ozona (O3) ilustrira sezonske varijacije i ukazuje na važnost praćenja koncentracija štetnih tvari u zraku. Iako su rezultati obećavajući, naglašava se potreba za nastavkom praćenja i smanjenjem emisija kako bi se očuvala kvaliteta zraka, posebno u urbanim područjima. Ovo istraživanje ukazuje na uspješnost 1D CNN u predviđanju koncentracija čestica u zraku, pridonoseći novim saznanjima i potičući daljnja istraživanja na polju kvalitete zraka.
Abstract (english)	This study focuses on improving the prediction of daily air particle concentrations at urban monitoring sites using 1D convolutional neural networks (CNN). It is hypothesized that 1D CNN, compared to algorithms like Random Forests, possesses greater predictive power. The prediction data is structured as multivariate time series. Data analysis was conducted using Python and MATLAB, and model parameter testing was performed in Python to identify optimal parameters and create the most efficient model. Results indicate that the CNN model outperformed other models, as evidenced by coefficients of determination and absolute errors. The predictions of the CNN model align with actual data, with all models suggesting potential for further optimization. Further analysis of ozone (O3) concentrations illustrates seasonal variations and underscores the importance of monitoring harmful air pollutant concentrations. While the results are promising, there is a need for ongoing monitoring and emission reduction efforts to preserve air quality, especially in urban areas. This research highlights the success of 1D CNN in predicting air particle concentrations, contributing new insights and encouraging further research in the field of air quality.
