Recent advances in medical imaging technologies generate a high volume of imaging data. Classification of cognitive outcome and disease status based on brain images is one of the most important tasks in neuroimaging studies. However it poses great challenge to the current classification methods due to the extremely high dimensionality and low signal to noise ratio in brain image data. In this article...
Malicious modification of integrated circuits, namely Hardware Trojan, has emerged as a major security threat. Since it is extremely difficult to detect the presence of such small Trojan circuits using only logic test or side-channel analysis, this paper presents a novel test method combining logic test and side-channel test together. An 18-bit CORDIC IP core is adopted as a golden circuit, while...
Using the kernel trick idea and the kernels-as-features idea, we can construct two kinds of nonlinear feature spaces, where linear feature extraction algorithms can be employed to extract nonlinear features. In this correspondence, we study the relationship between the two kernel ideas applied to certain feature extraction algorithms such as linear discriminant analysis, principal component analysis,...
