This paper presents a novel approach for remaining useful life (RUL) prediction of rotating machinery using hierarchical deep neural networks (DNN). The different health stages are classified by a DNN-based health stage classifier trained by segmented degradation signal. This method builds several RUL predictors based on the health stages of the degradation process. Instead of modeling the entire...
Aiming at automated security test on communication protocols, this paper proposes an automated manipulation mechanism of testing procedure based on FSM (Finite State Machine), and designs an automated packet generation mechanism based on a protocol template library. The practical experiments and applications show that the automated security testing platform of communication protocols based on this...
Neural networks approach is an advanced methodology used for intrusion detection. As a type of neural network, Self-organizing Maps (SOM) is getting more attention in the field of intrusion detection. In this paper, some improvements on SOM algorithm are made in order to increase detection rate and improve the stability of intrusion detection, include: (1) Modify the strategy of ldquowinner-take-allrdquo...
