To “ Multi - Way Blockmodels for Analyzing Coordinated High - Dimensional Responses ”
To carry out parameter estimation in the proposed multi-way blockmodel, we developed a variational EM algorithm in a similar fashion to (Airoldi, 2007; Jordan et al., 1999) with inference detailed as follows. N 1 and 1 ≤ k ≤ N 2. The latent variables X are assumed to follow distribution q(X). By Jensen's inequality, we obtain the following lower bound on the observed data log-likelihood: (A.1) ...
متن کاملMulti-way Blockmodels for Analyzing Coordinated High-dimensional Responses.
We consider the problem of quantifying temporal coordination between multiple high-dimensional responses. We introduce a family of multi-way stochastic blockmodels suited for this problem, which avoids pre-processing steps such as binning and thresholding commonly adopted for this type of problems, in biology. We develop two inference procedures based on collapsed Gibbs sampling and variational...

متن کاملAnalyzing high-dimensional multispectral data
In this paper, through a series of specific examples, we illustrate some characteristics encountered in analyzing high dimensional multispectral data. The increased importance of the second order statistics in analyzing high dimensional data is illustrated, as is the shortcoming of classifiers such as the minimum distance classifier which rely on first order variations alone. We also illustrate...
متن کاملAnalyzing and Debugging Hierarchies of Multi-way Local Propagation Constraints
Multi-way local propagation constraints are a powerful and exible tool for implementing applications such as graphical user interfaces. We have built constraint solvers that maintain sets of preferential multiway constraints, and integrated them into user interface development environments. These solvers are based on the formal theory of constraint hierarchies, leaving weaker constraints unsati...
