We congratulate the authors for their interesting papers on boosting and related topics. Jiangdeals with the asymptotic consistency of Adaboost. Lugosi and Vayatis study the convex optimization of los...
DISCUSSION:THE DANTZIG SELECTOR:STATISTICAL ESTIMATION WHEN p IS MUCH LARGER THAN n
DANTZIG SELECTOR STATISTICAL ESTIMATION p IS MUCH LARGER THAN n
2015/8/21
This is a fascinating paper on an important topic: the choice of predictor variables in large-scale linear models. A previous paper in these pages attacked the same problem using the “LARS” algorithm ...
Discussion of: \Sequential Quasi-Monte-Carlo Sampling" by Mathieu Gerber and Nicolas Chopin
Mathieu Gerber Nicolas Chopin
2015/8/21
We congratulate Gerber and Chopin for a very interesting paper with much
promise for applications. SQMC is similar to array-RQMC (L'Ecuyer et al.,
2008), in using T sets of N points in [0;1]d
inste...
Discussion of ‘Maximum likelihood estimation of a multi-dimensional log-concave density’ by M. Cule, R. Samworth and M. Stewart
likelihood estimation multi-dimensional log-concave density

I started looking at log-concave distributions when I was searching for an appropriate model
for subpopulations of multivariate flow cytometry data about ten years ago. The use of log-concave

Discussion of “Latent Variable Graphical Model Selection via Convex Optimization”
Latent Variable Graphical Model Selection Convex Optimization
2015/6/17
We wish to congratulate the authors for their innovative contribution, which is bound to inspire much further research. We find latent variable model selection to be a fantastic application of matrix ...
A Discussion on the Different Notions of Symmetry of Differential Equations
Discussion Different Notions of Symmetry of Differential Equations
2011/1/19
A discussion is presented, within a simple unifying scheme, about dif-ferent types of symmetry of PDE’s, with the introduction and a precise characterization of the notions of “standard” and “weak” co...
Discussion on Lechicki and Spakowski's counterexample
Lechicki Spakowski's counterexample
2010/11/29
It is well-known that intersection of continuous correspondences can lost the continuity
property. Lechicki and Spakowski’s theorem says that intersection of H-lsc functions remains
H-lsc if the int...
