A Nonparametric Bayesian Approach to Sparse Estimation of Gaussian Graphical Models


A Nonparametric Bayesian Approach to Sparse Estimation of Gaussian Graphical Models – Convolutional neural networks (CNN) are a powerful model of structure in the visual world. This paper shows how a CNN can be used to efficiently learn a sparse representation of an unknown network structure from images. The proposed approach is based on an adversarial network that pretends that a random number generator is playing any trick that generates the network structure (i.e., a certain number of CNNs). As a consequence, CNNs trained on the network structure learn to make decisions based on certain network features. This formulation leads to a generalization of the CNN which is important in CNNs. We show that this model is applicable to a large variety of visual content types that may be useful for learning and generating data for future research.

The performance of neural network models used to classify images is studied. Given a set of images, a model learns to classify or generate hypotheses that explain the training statistics; i.e., the information in the image is encoded in a sequence-to-sequence model. A novel feature of this model is that it predicts the predictions directly, while being computationally efficient. In this work, we aim to develop a method that learns to predict the posterior distribution of an image from a sequence of images from which the model predicts the posterior distribution. We show that the model learns to correctly classify images generated from the posterior distribution, and derive a new algorithm to extract the model’s posterior from the sequential model.
