Prediction of protein secondary structure at high accuracy using a combination of many neural networks |
Abstract | ||
|---|---|---|
A protein secondary structure prediction protocol involving up to 800 neural network predictions has been developed by SBI-AT. An overall performance of 80% is obtained for three-state (helix, strand, coil) DSSP categories. Input to primary-layer neural networks includes sequence profiles, relative residue position, relative chain length, and amino-acid composition. Secondary structure predictions axe made for three consecutive residues simultaneously - a technique which we describe as 'output expansion' - which boosts the performance of second-layer structure-to-structure networks. Independent network predictions arise from 10-fold cross validated training and testing of 1032 protein sequences at both primary and secondary network layers. Network output activities axe converted to probabilities. Finally, 800 different predictions axe combined using a novel balloting procedure. |
