Abstract
Tri-Training algorithm belongs to semi-supervised algorithm
the initial classifier performance of the algorithm is influenced by the labeled samples. When the number of the labeled samples is insufficient
the classifier performance is relatively weak
which will affect the iteration later. Therefore
an improvement algorithm called IFS-Tri-Training(Tri-Training based on intuitionistic fuzzy sets) is proposed
the SOM algorithm is applied in the paper to build intuitionistic fuzzy sets
so the classifier can measure the unlabeled samples by more factors
which makes the efficiency of the unlabeled samples is increased and labeled sample set is expanded. The experimental result on UCI datasets shows that the classifier performance is improved and the method of studying unlabeled samples is important.
