<Xi Luo> develops <biostatistics> and <machine learning> methods for biomedical data. His institutional profile identifies applications in <neuroscience>, <genomics> and disease research.https://sph.uth.edu/faculty/index.htm?fac=pghNVLVTa9HXjk5wwNYG3A%3D%3D[Official Xi Luo research profile]{ref}
With <Tony Cai> and <Weidong Liu>, he developed CLIME for sparse <precision matrix> estimation. The method constrains the error of an approximate inverse of the sample <covariance matrix> and minimizes an entrywise absolute-value objective. Its computation separates into columnwise <linear programs>.<A Constrained L1 Minimization Approach to Sparse Precision Matrix Estimation by Tony Cai and others>[Section2, original formulation and columnwise decomposition]{ref}
