摘要:

弹性网络是最广泛使用的正则化算法之一,通常与通过惩罚极大似然的监督广义线性模型估计问题相关联。它的优良特性源自于$\ell_1$和$\ell_2$范数的组合,这赋予了该方法考虑变量之间的相关性来选择变量的能力。在过去的几年里,半监督方法,使用标记和未标记的数据,已成为统计研究的一个重要组成部分。然而,尽管有这种兴趣,很少有研究调查半监督弹性网络扩展。本文介绍了一种新的解决方案,稀疏特征的半监督学习的背景下,广义线性模型估计:广义半监督弹性网络(s2网),它扩展了监督弹性网络方法,具有一般的数学公式,涵盖,但不限于,回归和分类问题。我们在R中开发了一个灵活而快速的s2net实现,并使用真实和合成数据集来说明其优势。

英文摘要:

The elastic-net is among the most widely used types of regularization algorithms, commonly associated with the problem of supervised generalized linear model estimation via penalized maximum likelihood. Its nice properties originate from a combination of $\ell_1$ and $\ell_2$ norms, which endow this method with the ability to select variables taking into account the correlations between them. In the last few years, semi-supervised approaches, that use both labeled and unlabeled data, have become an important component in the statistical research. Despite this interest, however, few researches have investigated semi-supervised elastic-net extensions. This paper introduces a novel solution for semi-supervised learning of sparse features in the context of generalized linear model estimation: the generalized semi-supervised elastic-net (s2net), which extends the supervised elastic-net method, with a general mathematical formulation that covers, but is not limited to, both regression and classification problems. We develop a flexible and fast implementation for s2net in R, and its advantages are illustrated using both real and synthetic data sets.
