Recent rapid developments in information technology have enabled the collection of high-dimensional complex data including in engineering, economics, finance, biology, and health sciences. High-dimensional means that the number of features is very large and often far higher than the number of collected data samples. Additionally, data sets are increasingly complex and messy, making it even more challenging to identify the subset of features that predict well one or more outcome variable.

Several optimization and search methods have been proposed in the literature to tackle the problem of identifying the set of important predictors, including forward stepwise, Lasso, and mixed-integer optimization. Despite their success, modern applications in areas like genomics are challenging the existing methods by pushing the dimensionality of the data to ultra-high dimensionality, where p can be exponentially larger than n. For such ultra-high dimensional problems, the existing methods can be extremely slow or can have high prediction errors or both, making them impractical to use.

The proposed project aims at developing new methods that improve simultaneously computational performance, prediction accuracy and interpretability of sound statistical models for ultra-high dimensional complex data.
