Scalable Generalized Stochastic Graphical Models – While recent literature has addressed the problem of graph-based optimization of hierarchical networks, the most relevant applications typically involve optimization of a stochastic optimization problem on a small set of clusters. The problem is often assumed to be intractable and has attracted considerable attention in the past decade. In this work, we investigate the problem of constructing a Markov algorithm that performs sparse linear regression on a large dataset of graphs with a number of nodes that differ only by a small degree. Our algorithm first constructs a partition that is similar if not identical, then splits the partition into a set of nodes that are similar to the same set of nodes. We then use the partition to form a hierarchical structure that is a Gaussian mixture whose structure is the model’s latent space. We use the hierarchical structure as a test that characterizes the expected search space, and show that our algorithm is optimal on a wide set of examples ranging in size from large to small.

We present an in-depth comparison of two commonly used text classification methods. The first is a method which relies on a word-level feature dictionary for classification. The second is a combination of two word-level features, namely word similarity and classifier weight. For each of these two feature, we propose a novel method to learn the discriminant information of the corresponding word for training and compare to the corresponding model trained using two different word similarity metrics. We show that the proposed methods lead to significant improvements of accuracy and efficiency in terms of learning word levels, both for image classification and recognition tasks.
