Backward-Forward Least Angle Shrinkage for Sparse Quadratic Optimization

Zhou Tianyi; Tao Dacheng (Springer, 2010)

In compressed sensing and statistical society, dozens of algorithms have been developed to solve â¿¿1 penalized least square regression, but constrained sparse quadratic optimization (SQO) is still an open problem. In this ...
An Exponential Family Extension to Principal Component Analysis

Li Jun; Tao Dacheng (Springer, 2010)

In this paper, we present a unified probabilistic model for constrained factorisation models, which employs exponential family distributions to represent the constrained factors. Our main objective is to provide a versatile ...
Random Projection Tree and Multiview Embedding for Large-scale Image Retrieval

Xie Bo; Song Mingli; Mu Yang; Tao Dacheng (Springer, 2010)

Image retrieval on large-scale datasets is challenging. Current indexing schemes, such as k-d tree, suffer from the â¿¿curse of dimensionalityâ¿ . In addition, there is no principled approach to integrate various features ...
