The model is presented below . 4 The Model This study employs feed-forward artificial neu-ral networks with a backpropagation algorithm as computational models for the analysis of un-accusative/unergative distinction in Turkish . 4.1 Artificial Neural Networks and Learn-ing Paradigms An artificial neural network ( ANN ) is a compu-tational model that can be used as a non-linear statistical data modeling tool . ANNs are gener-ally used for deriving a function from observa-tions , in applications where the data are com-plex and it is difficult to devise a relationship
