Model-based co-clustering can be seen as a particularly valuable extension of model-based clustering for three main reasons: (1) while allowing parsimoniously a drastic reduction of both the number of lines/individuals and columns/variables of a data set, (2) it also allows interpretability of such a resulting reduced data set since initial individuals and features meaning is preserved in this latter; (3) moreover it benefits from the powerful mathematical statistics theory for both estimation and model selection. Hence, many authors produced new advances on this topic in the recent years, and this paper offers a general update of the related literature. In addition, it is the opportunity to pass two messages, supported by specific research materials: (1) co-clustering still requires some new and motivating researches for fixing some well-identified estimation issues, (2) co-clustering is probably one of the most promising clustering approach to be addressed in the (very) high dimension setting, which corresponds to the global trend on modern data sets
