Artificial neural network and multiple linear regression modelling for prediction of moisture content of red beetroots during ultrasound assisted vacuum drying

Abstract

The present work aimed to evaluate the possibility of artificial neural networks (ANN) and multiple linear regression (MLR) to characterize the drying kinetics of red beetroot slices during ultrasound assisted vacuum drying. The ANN model was chosen due to impact of the hidden layer's neuron number and size. The best ANN model was obtained by three layers (5 inputs, 15 neurons in one hidden layer and 1 output) with RMSE of 0.0117, MAPE of 2.293 and R2 of 0.9996 for all data. The results showed that the ANN is a more effective predictive tool since it can yield better outcomes than MLR.

Ultrases destekli vakumlu kurutma sırasında kırmızı pancarların nem oranının tahmini için yapay sinir ağı ve çoklu doğrusal regresyon modellemesi

Abstract

Bu çalışma, yapay sinir ağları (ANN) ve çoklu doğrusal regresyon (MLR) yöntemlerinin, ultrason destekli vakumlu kurutma sırasında kırmızı pancar dilimlerinin kuruma kinetiğini karakterize etme olasılığını değerlendirmeyi amaçlamaktadır. YSA modeli, gizli katmanın nöron sayısı ve boyutunun etkisi göz önünde bulundurularak seçilmiştir. En iyi YSA modeli, tüm veriler için RMSE değeri 0,0117, MAPE değeri 2,293 ve R2 değeri 0,9996 olan üç katmandan (5 giriş, bir gizli katmanda 15 nöron ve 1 çıkış) elde edilmiştir. Sonuçlar, YSA'nın MLR’ den daha iyi sonuçlar verebildiği için daha etkili bir tahminleme aracı olduğunu göstermiştir.
