Parallel Implementation of Distributed Global Optimization (DGO)
Homayoun Valafar, Okan K. Ersoy, Farmaraz Valafar
Parallel implementations of distributed global optimization (DGO) [13] on MP-1 and NCUBE parallel computers revealed an approximate O(n) increase in the performance of this algorit…
Reduction in the complexity of 1D 1H-NMR spectra by the use of Frequency to Information Transformation
Homayoun Valafar, Faramarz Valafar
Analysis of 1H-NMR spectra is often hindered by large variations that occur during the collection of these spectra. Large solvent and standard peaks, base line drift and negative p…
Distributed Global Optimization (DGO)
Homayoun Valafar, Okan K. Ersoy, Faramarz Valafar
A new technique of global optimization and its applications in particular to neural networks are presented. The algorithm is also compared to other global optimization algorithms s…
TALI: Protein Structure Alignment Using Backbone Torsion Angles
Xijiang Miao, Michael G. Bryson, Homayoun Valafar
This article introduces a novel protein structure alignment method (named TALI) based on the protein backbone torsion angle instead of the more traditional distance matrix. Because…
An Investigation in Optimal Encoding of Protein Primary Sequence for Structure Prediction by Artificial Neural Networks
Aaron Hein, Casey Cole, Homayoun Valafar
Machine learning and the use of neural networks has increased precipitously over the past few years primarily due to the ever-increasing accessibility to data and the growth of com…
A Comparative study of Artificial Neural Networks Using Reinforcement learning and Multidimensional Bayesian Classification Using Parzen Density Estimation for Identification of GC-EIMS Spectra of Partially Methylated Alditol Acetates
Faramarz Valafar, Homayoun Valafar
This study reports the development of a pattern recognition search engine for a World Wide Web-based database of gas chromatography-electron impact mass spectra (GC-EIMS) of partia…
