Diverse areas of scientific research and everyday life, such as healthcare, biomedicine and finance, are now deluged with high-dimensional data and big data. There is a need of data mining and prediction techniques for finding patterns and discovering knowledge from such data. In this talk I will present our feature selection and learning methods for handling such data effectively and efficiently. The feature selection methods integrate intrinsic discriminative information and exploit global optimization techniques on Markov random fields, giving rise to a closed-form solution of linear complexity. The learning methods are built within our minimax pattern learning framework, extending lasso-type sparse representation and possessing efficient complexity and fast convergence. I will present both supervised and unsupervised models that exploit jointly representation and learning, with mathematical modeling emphasized. It is expected that these methods will have potentially a significant impact on various fields such as medicine and science.
