Investigation of neural networks’ ability to identify RNA promoters

In my final study project at HTX Hillerod I tried to solve the biotechnological problem of finding genes in a DNA string using an artificial neural network. I wrote the neural network in C++ and trained it using specific sequences found at the beginning of genes, called RNA promoters. In an experiment where the neural network was trained with backprogration using a constant training rate, an error rate of 30% was reached on the test set. I found that further improvements could be made by making the training rate a function of the error rate. An error rate of 22% on the test set was reached using this method. I therefore concluded that the developed neural network to some degree was capable of identifying promoters.
