When the pressure sensor is used, temperature changes bring about actual measurement errors . A suitable temperature compensation algorithm can be selected to reduce the additive errors and improve the accuracy of measurement. Support vector machine (SVM) is based on the principle of minimum structural risk, and has high precision. Least squares support vector regression (LS-SVR) is adopted to adjust...
The technique of orthogonal frequency division multiplexing (OFDM) channel estimation is an important topic being studied in the fourth generation mobile communications. It is significant in increasing the capacity of the system and the efficiency of the frequency spectrum. The traditional channel estimation algorithms have the disadvantages of performance worsening and they are all hard to obtain...
The pre-diagnosis to type 2 diabetes, and the effective prophylaxis and treatment of its complication is to be worthy paying attention to. So an intelligent diagnosis based on quantum particle swarm optimization (QPSO) algorithm and weighted least squares support vector machines (WLS-SVM) is presented, which can overcome the disadvantage of large sample data, slow model-building and rather large deviation...
