Risk Comparisons in Linear Regression: Implicit Regularization Dominates Explicit Regularization
A new research paper published on arXiv analyzes the performance of gradient descent (GD) compared to ridge regression and online stochastic gradient descent (SGD) in linear regression tasks. The study finds that GD consistently outperforms ridge regression, offering comparable or superior risk profiles. However, GD and SGD show incomparable performance, with each algorithm excelling in different problem types. AI
