Learning Sparse Deep Feedforward Networks via Tree Skeleton Expansion
Zhourong Chen, Xiaopeng Li, Nevin L. Zhang
Despite the popularity of deep learning, structure learning for deep models remains a relatively under-explored area. In contrast, structure learning has been studied extensively f…
Building Sparse Deep Feedforward Networks using Tree Receptive Fields
Xiaopeng Li, Zhourong Chen, Nevin L. Zhang
Sparse connectivity is an important factor behind the success of convolutional neural networks and recurrent neural networks. In this paper, we consider the problem of learning spa…
Learning Latent Superstructures in Variational Autoencoders for Deep Multidimensional Clustering
Xiaopeng Li, Zhourong Chen, Leonard K. M. Poon +1
We investigate a variant of variational autoencoders where there is a superstructure of discrete latent variables on top of the latent features. In general, our superstructure is a…
