Support vector machines have been extensively used in machine learning because of its efficiency and its theoretical background. This paper focuses on transductive support vector machines (TSVM) for classification and construct a new algorithm - unconstrained transductive support vector machines (UTSVM). After researching on the special construction of primal problem in TSVM, we transform it to an unconstrained problem and then smooth the derived problem in order to apply usual optimization methods.
