A mahalanobis hyperellipsoidal learning machine class incremental learning algorithm
Qin, Yuping; Karimi, Hamid Reza; Li, Dan; Lun, Shuxian; Zhang, Aihua (Journal article; Peer reviewed, 2014)A Mahalanobis hyperellipsoidal learning machine class incremental learning algorithm is proposed. To each class sample, the hyperellipsoidal that encloses as many as possible and pushes the outlier samples away is trained ... -
A novel mathematical formula for retrieval algorithm
Qin, Yuping; Karimi, Hamid Reza; Zhang, Aihua; Leng, Qiangkui (Journal article; Peer reviewed, 2014)A method is proposed to retrieve mathematical formula in LaTeX documents. Firstly, we represent the retrieved mathematical formula by binary tree according to its LaTeX description, normalize the structure of the binary ... -
Development of La3+ Doped CeOthick film humidity sensors
Wang, Chunjie; Zhang, Aihua; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)The humidity sensitive characteristics of the sensor fabricated from 10 mol% Ladoped CeOnanopowders with particle size 17.26 nm synthesized via hydrothermal method were investigated at different frequencies. It was found ... -
Effects of surfactants on the performance of CeO2 humidity sensor
Wang, Chunjie; Zhang, Aihua; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)Nanosized CeO 2 powders were synthesized via hydrothermal method with different types of surfactants (polyethylene glycol (PEG), cetyltrimethylammonium bromide (CTAB), and sodium dodecylbenzenesulfonate (SDBS)). X-ray ... -
New strategy for analog circuit performance evaluation under disturbance and fault value
Zhang, Aihua; Wang, Yongchao; Chen, Chen; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)Focus on this issue of disturbance and fault value is inevitable in data collection about analog circuit. A novel strategy is developed for analog circuit online performance evaluation based on fuzzy learning and double ... -
Research on amplifier performance evaluation based on δ-support vector regression
Huo, Xing; Zhang, Aihua; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)Focusing on the amplifier performance evaluation demand, a novel evaluation strategy based on δ-support vector regression (δ-SVR) is proposed in this paper. Lower computer calculation demand is considered firstly. And this ... -
Robust control allocation for spacecraft attitude stabilization under actuator faults and uncertainty
Zhang, Aihua; Wang, Yongchao; Zhang, Zhiqiang; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)A robust control allocation scheme is developed for rigid spacecraft attitude stabilization in the presence of actuator partial loss fault, actuator failure, and actuator misalignment. First, a neural network fault detection ...
