Model Approximation Using Cascade of Tree Decompositions
Navid Tafaghodi Khajavi, Anthony Kuh
In this paper, we present a general, multistage framework for graphical model approximation using a cascade of models such as trees. In particular, we look at the problem of covari…

Latent Tree Approximation in Linear Model
Navid Tafaghodi Khajavi
We consider the problem of learning underlying tree structure from noisy, mixed data obtained from a linear model. To achieve this, we use the expectation maximization algorithm co…

The Quality of the Covariance Selection Through Detection Problem and AUC Bounds
Navid Tafaghodi Khajavi, Anthony Kuh
We consider the problem of quantifying the quality of a model selection problem for a graphical model. We discuss this by formulating the problem as a detection problem. Model sele…
