On confidence intervals for precision matrices and the eigendecomposition of covariance matrices
Teodora Popordanoska, Aleksei Tiulpin, Wacha Bounliphone +1
The eigendecomposition of a matrix is the central procedure in probabilistic models based on matrix factorization, for instance principal component analysis and topic models. Quant…
Fast Non-Parametric Tests of Relative Dependency and Similarity
Wacha Bounliphone, Eugene Belilovsky, Arthur Tenenhaus +3
We introduce two novel non-parametric statistical hypothesis tests. The first test, called the relative test of dependency, enables us to determine whether one source variable is s…
A U-statistic Approach to Hypothesis Testing for Structure Discovery in Undirected Graphical Models
Wacha Bounliphone, Matthew Blaschko
Structure discovery in graphical models is the determination of the topology of a graph that encodes conditional independence properties of the joint distribution of all variables…
A Test of Relative Similarity For Model Selection in Generative Models
Wacha Bounliphone, Eugene Belilovsky, Matthew B. Blaschko +2
Probabilistic generative models provide a powerful framework for representing data that avoids the expense of manual annotation typically needed by discriminative approaches. Model…
A low variance consistent test of relative dependency
Wacha Bounliphone, Arthur Gretton, Arthur Tenenhaus +1
We describe a novel non-parametric statistical hypothesis test of relative dependence between a source variable and two candidate target variables. Such a test enables us to determ…
