The Support Vector Machines (SVM) has been an important classification technique in both machine learning and statistics communities. The robust SVM is an improved version of the SVM so that the resulting classifier can be less sensitive to...

We consider the problem of performing unsupervised learning in the presence of outliers - that is, observations that do not come from the same distribution as the rest of the data. It is known that in this setting, standard approaches for u...

In recent years, developments in molecular biotechnology have led to the increased promise of detecting and validating biomarkers, or molecular markers that relate to various biological or medical outcomes. Proteomics, the direct study of p...
Determination of proportionality in two-part models and analysis of Multi-Ethnic Study of Atherosclerosis (MESA) [0.03%]
两部分模型中的比例性判定及动脉粥样硬化多种族研究(MESA)数据分析

Anna Liu et al.
In MESA (Multi-Ethnic Study of Atherosclerosis), it is of interest to model the development and progression of CAC (coronary artery calcium). With about half of the CAC scores equal to zero and the rest continuously distributed, semiparamet...

This paper considers the problem of optimal false discovery rate control when the test statistics are dependent. An optimal joint oracle procedure, which minimizes the false non-discovery rate subject to a constraint on the false discovery ...
Cosine series representation of 3D curves and its application to white matter fiber bundles in diffusion tensor imaging [0.03%]
余弦级数表示的三维曲线及其在扩散张量成像中白质纤维束中的应用研究
