Improved Transductive Support Vector Machine for a Small Labelled Set in Motor Imagery-Based Brain-Computer Interface

Algorithm 1

The proposed ITSVM algorithm.

	Input: the initial labelled set: .
	Input: the unlabelled set: .
	Output: the optimal hyperplane parameter group .
	Initialize with a traditional SVM on the initial labelled set;
	Compute
	Set for and ;
	for  = 1 to 5 do
	Solve the following minimization problem by using SMO to find coefficients:
