Sparse Linear Regression

Sparse linear regression aims to identify a small subset of relevant features from a high-dimensional dataset to predict a response variable, prioritizing both accuracy and interpretability. Current research emphasizes developing computationally efficient algorithms, such as those based on iterative reweighted least squares, LASSO variations (including contextual and rescaled versions), and techniques leveraging singular value decomposition or other matrix factorization methods, to handle high-dimensionality, correlated features, and outliers. These advancements are crucial for various applications, including model discovery in dynamical systems, biomedical data analysis, and improving the efficiency and robustness of machine learning models. The field also actively explores theoretical limits and computational-statistical tradeoffs, seeking to understand the fundamental barriers to efficient sparse regression.
