Maximum Joint Probability With Multiple Representations for Clustering
Rui Zhang, Hongyuan Zhang, Xuelong Li · IEEE Transactions on Neural Networks and Learning Systems · 2021
Classical generative models in unsupervised learning intend to maximize p(X) . In practice, samples may have multiple representations caused by various transformations, measurements, and so on. Therefore, it is crucial to integrate information from different representations, and lots of models have been developed. However, most of them fail to incorporate the prior information about data distribution p(X) to distinguish representations. In this article, we propose a novel clustering framework that attempts to maximize the joint probability of data and parameters. Under this framework, the prior distribution can be employed to measure the rationality of diverse representations. K -means is a special case of the proposed framework. Meanwhile, a specific clustering model considering both multiple kernels and multiple views is derived to verify the validity of the designed framework and model.
