Sparse modeling: some unifying theory and "topic-imaging"

Sparse modeling: some unifying theory and "topic-imaging"

This video was recorded at 14th International Conference on Artificial Intelligence and Statistics (AISTATS), Ft. Lauderdale 2011. Information technology has enabled collection of massive amounts of data in science, engineering, social science, finance and beyond. Extracting useful information from massive and high-dimensional data is the focus of today's statistical research and practice. After broad success of statistical machine learning on prediction through regularization, interpretability is gaining attention and sparsity is being used as its proxy. With the virtues of both regularization and sparsity, sparse modeling methods (e.g., Lasso) has attracted much attention for theoretial research and for data modeling.
