通过去除不相关和多余的特征，特征选择旨在找到具有良好泛化能力的原始特征的紧凑表示。 随着无标签数据的普及，无监督特征选择已显示出可有效减轻维数的诅咒，对于全面分析和理解无标签高维数据的无数至关重要，这是由于子空间聚类中低秩表示法的成功所致，我们提出了一种用于无监督特征选择的正则化自我表示（RSR）模型，其中每个特征都可以表示为其相关特征的线性组合。 通过使用L-2，L-1-范数来表征表示系数矩阵和表示残差矩阵，RSR有效地选择了代表性特征并确保了对异常值的鲁棒性。 如果某个特征很重要，则它将参与大多数其他特征的表示，从而导致出现大量的表示系数，反之亦然。 对合成数据和现实世界数据进行的实验分析表明，该方法可以有效地识别代表性特征，在聚类精度，冗余减少和分类精度方面优于许多最新的无监督特征选择方法。

Grammar learning has been a bottleneck problem for a long time. In this paper, we propose a method of semantic separator learning, a special case of grammar learning. The method is based on the hypothesis that some classes of words, called semantic separators, split a sentence into several constituents. The semantic separators are represented by words together with their part-of-speech tags and other information so that rich semantic information can be involved. In the method, we first identify t
