Paper Abstract
The range of applications of Raman-based classification has expanded significantly, including applications in
bacterial identification. The first stage in the classification of Raman spectra is commonly some form of preprocessing.
This pre-processing greatly affects the accuracy of the results and introduces user bias and over-fitting
effects. In this paper, we propose the use of Support Vector Machines with a novel correlation kernel. Results,
obtained from the analysis of Raman spectra of bacteria, illustrate that the correlation kernel is "self-normalizing"
and produces superior classification performance with minimal pre-processing, even on highly-noisy data obtained
using inexpensive equipment. In addition, the performance does not degrade when applied to distinct test sets,
a key feature of a clinically viable diagnostic application of Raman Spectroscopy.
