Copyright © 2019 Tech Science Press The defense techniques for machine learning are critical yet challenging due to the number and type of attacks for widely applied machine learning algorithms are significantly increasing. Among these attacks, the poisoning attack, which disturbs machine learning algorithms by injecting poisoning samples, is an attack with the greatest threat. In this paper, we focus on analyzing the characteristics of positioning samples and propose a novel sample evaluation method to defend against the poisoning attack catering for the characteristics of poisoning samples. To capture the intrinsic data characteristics from heterogeneous aspects, we first evaluate training data by multiple criteria, each of which is reformulated from a spectral clustering. Then, we integrate the multiple evaluation scores generated by the multiple criteria through the proposed multiple spectral clustering aggregation (MSCA) method. Finally, we use the unified score as the indicator of poisoning attack samples. Experimental results on intrusion detection data sets show that MSCA significantly outperforms the K-means outlier detection in terms of data legality evaluation and poisoning attack detection.
