Survey of active learning for networked data
Xinlei Wang, Bo Yang, Jing Huang
Classification in networked data is a popular research of complex network. Because of the large scale of networked data and the shortage of training data, active learning, which is an effective classification method for sparse data in machine learning, is often applied to networked data classification...

An Algorithm of the Time-delay Alignment Based on Iterative Estimation
Yang Li, Xiao-yi Zhang, Yun-peng Hu, Zhi-xiang Shen, Biao Zhao
A novel algorithm aligning the time-delay of each signal received by a uniform antenna array is presented. In order to solve the problem that time-delay alignment performance is poor at the low signal-to-noise ratio (SNR) value, the proposed algorithm makes use of iterative estimation. Then we analyze...
