Two approaches to solving the problem of clustering with gaps for a specified number of clusters are considered. The first approach is based on restoring the values of unknown attributes and solving the problem of clustering of calculated complete data. The second approach is based on solving a finite set of tasks of clustering of corresponding to incomplete data complete sample descriptions and the construction of collective decision. For both approaches, the clustering quality criteria have been proposed as functions of incomplete descriptions. Results of practical experiments are considered.
