Many modern scientific investigations require the analysis of high dimensional data. Examples include genomic and proteomic data, spatial-temporal data, network data, and many others. Simultaneous variable selection and parameter estimation play a central role in such investigations. There is now an immense literature on variable selection, and penalized regression methods are becoming increasingly popular. Much new development has been published in recent years by leading statistical journals.

The application of linear regression models for high-dimensional data analysis is a challenging task. Regularization techniques, such as adaptive penalized least-squares, have attracted much attention in the literature. Penalized regression is a technique for mitigating difficulties arising from collinearity and high-dimensionality. This approach necessarily incurs an estimation bias, while reducing the variance of the estimator. A tuning parameter is needed to adjust the effect of the penalization so that a desirable balance between model parsimony and goodness-of-fit can be achieved. Different forms of penalty functions have been studied intensively over the last 10-15 years. Examples include the LASSO and its many variants (such as adaptive LASSO, group LASSO, relaxed LASSO, and so on), the SCAD, the Dantzig selector, and the elastic net, to name just a few. More recently, some of these penalization/regularization techniques have been extended to deal with the estimation of large covariance matrices, and the analysis of complex dependence structures such as networks and graphs.

The purpose of this workshop is to stimulate research in an informal setting, and to foster the interaction of researchers in the area of high-dimensional data analysis. It will provide a venue for participants to meet leading researches of this field in an intimate setting, providing maximal chance for interaction and discussion. The objectives include:

(1) to highlight and expand the breadth of existing methods in high-dimensional data analysis and their potential for the advance of both mathematical and statistical sciences;

(2) to identify important directions for future research in the theory of regularization methods, in algorithmic development, and in methodology for different application areas;

(3) to facilitate collaboration between theoretical and subject-area researchers; and

(4) to provide opportunities for highly qualified personnel to meet and interact with leading researchers from countries around the world.

The workshop is being jointly held as a satellite meeting ahead of the 39th Annual Meeting of the Statistical Society of Canada.
