演讲简介

Deep learning has been pervasively applied in various domains and gained tremendous success. However, its adoption in the area of cyber security is still limited, due to the lack of interpretability. In this talk, I will present our work, LEMNA, a high-fidelity explanation method dedicated to the application of deep learning in reverse engineering. The core idea of LEMNA is to approximate a local area of the complex deep learning decision boundary using an interpretable model, which essentially captures the set of key features to classify an input sample. The local interpretable model is specially designed to accommodate two requirements of explaining deep learning in reverse engineering: (1) handling feature dependency (2) handling nonlinear local boundaries. In this talk, I will also demonstrate the use of LEMNA to help machine learning developers validate model behavior, troubleshoot classification errors, and automatically patch the errors of the target models.
