                            <p>In this study, we constructed the models to predict gold prices through neural network by using some variables that are assumed to affect gold prices such as silver prices, Brent prices, USD/EUR parity, EuroNext 100 index, Dow Jones Index, 13-weeks the US bond interest rates, CPI in the US. The estimation results of these artificial neural network models are compared with real values by using calculated performance criteria such as R2, RMSE, MAE and MAPE  %  values. The findings suggest that artificial neural networks can be successfully used to estimate the gold prices. According to the results of sensitivity analysis, the major factors that affect the gold prices are silver and oil prices</p></trans-abstract>

Yapay sinir ağları ile kurulan modellerden elde edilen tahmin sonuçları, gerçek değerler ile R2, RMSE, MAE ve MAPE  %  gibi performans kriterleri hesaplanarak karşılaştırılmıştır. Elde edilen bulgular yapay sinir ağlarının altın fiyatlarının tahmininde başarı ile kullanılabileceğini göstermektedir. Yapılan duyarlılık analizinin sonuçları değerlendirildiğinde altın fiyatlarını etkileyen faktörlerin başında gümüş ve petrol fiyatlarının geldiği tespit edilmiştir.</p></abstract>
