Abstract :
The limitations of backpropagation used as a function extrapolator were investigated. Four common functions were used to investigate the network´s extrapolation capability. The purpose of the experiment was to determine whether neural networks are capable of extrapolation and, if so, to determine the range for which networks can extrapolate. The authors show that neural networks cannot extrapolate and offer an explanation to support this result
