Low Latency, High Throughput, and Less Complex VLSI Architecture for 2D-DFT
: This paper proposes a pipelined, systolic architecture for two- dimensional discrete Fourier transform computation which is highly concurrent. The architecture consists of two, o...

A Bound on the Performance of LDA in Randomly Projected Data Spaces
We consider the problem of classification in nonadaptive dimensionality reduction. Specifically, we bound the increase in classification error of Fisher’s Linear Discriminant...

Image analysis with regularized Laplacian eigenmaps
Many classes of image data span a low dimensional nonlinear space embedded in the natural high dimensional image space. We adopt and generalize a recently proposed dimensionality ...
