Imaging genetics is an effective … WebJul 11, 2016 · Recently, sparse unmixing (SU) of hyperspectral data has received particular attention for analyzing remote sensing images. However, most SU methods are based on the commonly admitted linear mixing model (LMM), which ignores the possible nonlinear effects (i.e., nonlinearity). In this paper, we propose a new method named robust …

WebOur approach relies on the use of Time-Varying Group Sparse Additive Models (TV-GroupSpAM) for high-dimensional, functional regression. This new model detects a sparse set of genomic loci that are associated with trait dynamics, and demonstrates increased statistical power over existing methods.

New sparse shrunk additive models To improve the sparsity of SALSA, we propose a new al-gorithm, named as sparse shrunk additve models (SSAM). Some sparse methods (e.g., Lasso (Tibshirani,1996) and kernelized Lasso (Roth,2004)) can be considered as the spe-cial cases of our new model.
