LS-SVM Based Self-Learning Tremor Controller for Microsurgery
One of the main problems for effective control of a minimally invasive surgery (MIS) is the imprecision that caused by hand tremor. In this paper, a novel adaptive filter, the least squares support vector machines adaptive filter (LS-SVMAF), is proposed to overcome this problem. Compared with traditional methods like multi-layer perceptron (MLP), LS-SVM shows a superior performance of nonlinear modeling with small scale of data set or high dimensional input space. Simulation results demonstrate the effectiveness of the proposed filter and its superior performance over its competing rivals.
