Standard LASSO

Standard LASSO (Least Absolute Shrinkage and Selection Operator) is a regression technique that performs variable selection and regularization by shrinking coefficients towards zero using an L1 penalty. Current research focuses on improving LASSO's efficiency and robustness, including developing faster algorithms (like those based on block-coordinate descent), addressing challenges posed by high dimensionality and correlated covariates (through techniques such as rescaling and latent variable modeling), and enhancing its applicability in various contexts such as multi-omics data analysis and causal inference (e.g., estimating conditional average treatment effects). The widespread use of LASSO across diverse fields, from genomics to imaging, highlights its significance in extracting meaningful insights from high-dimensional data and improving the accuracy and interpretability of predictive models.
