Background Practitioners and researchers often found the intrinsic representations of high-dimensional problems has much fewer independent variables. However such intrinsic structure may not be easily discovered due to noises and other factors.A supervised transformation scheme RST is proposed to transform features into lower dimensional spaces for classification tasks. The proposed algorithm recursively...
Commercial anti-virus software traditionally memorizes specific byte sequences (known as “signatures”) in the file contents of previously encountered malware. However, malware authors can evade signature-based detection in many ways; for instance, by using obfuscation techniques such as “packing” (encryption or compression) to hide snippets of malicious code; by writing metamorphic malware; or by...
For very large datasets, random projections (RP) have become the tool of choice for dimensionality reduction. This is due to the computational complexity of principal component analysis. However, the recent development of randomized principal component analysis (RPCA) has opened up the possibility of obtaining approximate principal components on very large datasets. In this paper, we compare the performance...
