DDoS attack is hard to detect in backbone network,for the reason that attack flows are distributed in multiple links and prone to be masked by tremendous amounts of background traffic.To solve this problem,a detection method based on global abnormal correlation analysis is proposed.The change of correlation between traffic caused by attack flows is exploited for attack detection,the correlation between potentially anomalous traffic is extracted by principle component analysis,and its change degree is used as an indicator of attack.Evaluation shows its effectiveness and proves that it overcomes the difficulties in detecting relatively low volume of DDoS attack transiting in backbone network.Comparing with existing network-wide detection method,it achieves higher detection rate.

Developing a machine's ability to recognize emotion states is one of the hallmarks of emotional intelligence and important prerequisite for high-level human computer interaction（HCI）.Recording and recognizing physiological signals of emotion has become an increasingly important field of research in affective computing and HCI.For the problem of feature redundancy of physiological signals-based emotion recognition and low efficiency of traditional feature reduction algorithms on great sample data,a hybrid intelligent optimization algorithm based on the simulated annealing algorithm and particle swarm optimization algorithm（SA-PSO）was proposed to solve the problem of emotion feature selection.Then a weighted discrete-KNN classifier（WD-KNN）was presented to classify features by making full use of emotion sample information.The recognition rate and efficiency was increased and the algorithm's validity was verified through the analysis of experimental simulation data and the comparison of several recognition methods.
