摘要:

特征选择是机器学习中的一个重要步骤,因为它可以提高预测精度,同时降低高维数据的维数灾难。神经网络在解决许多非线性学习问题方面取得了巨大的成功。在这里,我们提出了新的基于神经网络的特征选择方法,该方法引入了两个约束,满足这两个约束会导致稀疏FS层。我们已经进行了广泛的实验,合成和真实世界的数据,以评估性能的建议FS。在实验中,我们专注于高维,低样本量的数据,因为这些代表了特征选择的主要挑战。实验结果表明,提出的基于规范化约束稀疏神经网络层的特征选择方法(SNEL-FS)能够有效地选择重要特征,并且与其他传统的FS方法相比具有更好的性能。

英文摘要:

Feature selection is important step in machine learning since it has shown to improve prediction accuracy while depressing the curse of dimensionality of high dimensional data. The neural networks have experienced tremendous success in solving many nonlinear learning problems. Here, we propose new neural-network based feature selection approach that introduces two constrains, the satisfying of which leads to sparse FS layer. We have performed extensive experiments on synthetic and real world data to evaluate performance of the proposed FS. In experiments we focus on the high dimension, low sample size data since those represent the main challenge for feature selection. The results confirm that proposed Feature Selection Based on Sparse Neural Network Layer with Normalizing Constraints (SNEL-FS) is able to select the important features and yields superior performance compared to other conventional FS methods.
