Examining the effect of imperfect transmit antenna selection (TAS) caused by the feedback link errors on the performance of hybrid TAS/space-time block co ding (STBC) with selection combining (SC) (i....
Discriminative Sparse Coding on Multi-Manifold for Data Representation and Classification
Discriminative Sparse Coding Multi-Manifold for Data Representation Classification
2012/9/18
Sparse coding has been popularly used as an effective data represen-tation method in various applications, such as computer vision, medical imaging and bioinformatics, etc. However, the conventional s...
Introduction of the so called K-means features caused significant discussion in the deep learning community. Despite their simplicity, these features have achieved state of the art performance on seve...
Closed-Form EM for Sparse Coding and Its Application to Source Separation
Closed-Form EM Sparse Coding Source Separation
2011/6/17
We define and discuss the first sparse coding algorithm based on closed-form EM
updates and continuous latent variables. The underlying generativemodel consists
of a flexibly parameterized ‘spike-an...
K-Dimensional Coding Schemes in Hilbert Spaces
Empirical risk minimization estimation bounds K-means clus-tering and vector quantization statistical learning
2010/3/10
This paper presents a general coding method where data in
a Hilbert space are represented by finite dimensional coding vectors. The
method is based on empirical risk minimization within a certain cl...

Algebraic statistics Complex coding Mixed-level designs Regularfraction Orthogonal arrays
2010/4/27
In a general fractional factorial design, the n-levels of a factor are coded by the n-th
roots of the unity. This device allows a full generalization to mixed-level designs of
the theory of the poly...
