| Researchers at Purdue University have developed an algorithm that subtly changes input data to induce misclassification to improve linear discriminant analysis of data. Linear analyses complement deep neural networks by providing straightforward statistically tractable avenues for mining high-dimensional data. The algorithm developed by Purdue researchers can remove "over-fitting" numerical instabilities inherent in common linear discriminant analysis methods. The algorithm was used to produce subtle spectral changes that were undetectable to the human eye to misclassify Raman spectra, in turn leading to major improvements in the statistical confidence with which spectra were assigned to different chemical species. This algorithm is compatible with broad classes of data analysis challenges, in which linear analysis methods play a primary or supporting role. Advantages: -Undetectable data misclassification -Identification of stronger classifiers Potential Applications: -Data Mining /Classification -Military/Defense -Spectroscopy/Measurement Science |
