Peek-a-Boo: What (More) is Disguised in a Randomly Weighted Neural Network, and How to Find It Efficiently

no code implementations ICLR 2022 Xiaohan Chen, Jason Zhang, Zhangyang Wang

In this work, we define an extended class of subnetworks in randomly initialized NNs called disguised subnetworks, which are not only "hidden" in the random networks but also "disguised" -- hence can only be "unmasked" with certain transformations on weights.

Machine Learning With Feature Selection Using Principal Component Analysis for Malware Detection: A Case Study

no code implementations10 Feb 2019 Jason Zhang

In this paper, we have proposed a novel approach by extending our recently suggested artificial neural network (ANN) based model with feature selection using the principal component analysis (PCA) technique for malware detection.

MLPdf: An Effective Machine Learning Based Approach for PDF Malware Detection

no code implementations21 Aug 2018 Jason Zhang

Due to the popularity of portable document format (PDF) and increasing number of vulnerabilities in major PDF viewer applications, malware writers continue to use it to deliver malware via web downloads, email attachments and other methods in both targeted and non-targeted attacks.
