Image Clustering without Ground Truth [article]

Abhisek Dash, Sujoy Chatterjee, Tripti Prasad, Malay Bhattacharyya
2016 arXiv   pre-print
In this paper, we introduce a crowd-powered model to collect solutions of image clustering from the general crowd and pose it as a clustering ensemble problem with variable number of clusters.  ...  Given multiple such clustering solutions, it is a challenging task to obtain an ensemble of these solutions.  ...  All the authors would like to thank the crowd contributors involved in this work.  ...
