Multi-manifold clustering: A graph-constrained deep nonparametric method

作者:

Highlights:

• Two new nonparametric methods are proposed to extend the application scope of the conventional Dirichlet process mixture model.

• A deep learning based nonparametric algorithm is proposed for the image generation and clustering task, in which the cluster number will not be pre-specified but estimated by model.

• A new deep neural network architecture named Graph-VAE has been presented for the manifold and posterior probability approximation.

• A mean field variational inference algorithm is derived, which incorporates the learning procedure with the Graph-VAE to handle the non-conjugated parameter estimation.
