  This Paper represents a literature review of Swarm intelligence algorithm in
the area of semi-supervised classification. There are many research papers for
applying swarm intelligence algorithms in the area of machine learning. Some
algorithms of SI are applied in the area of ML either solely or hybrid with
other ML algorithms. SI algorithms are also used for tuning parameters of ML
algorithm, or as a backbone for ML algorithms. This paper introduces a brief
literature review for applying swarm intelligence algorithms in the field of
semi-supervised learning
