Heterogeneous Data Clustering Considering Multiple User-provided Constraints

Yue Huang
2019 International Journal of Computers Communications & Control  
Although numerous clustering methods have achieved remarkable success, current clustering methods for heterogeneous networks tend to consider only internal information of the dataset.  ...  Clustering on heterogeneous networks which consist of multi-typed objects and links has proved to be a useful technique in many scenarios.  ...  Huang In addition, relative to unsupervised clustering, semi-supervised clustering still has a small amount of useful sample information.  ...
