A new research paper explores the phenomenon of "benign misfitting" in linear regression models, where a model that performs poorly on training data can still generalize well to new, unseen data. This occurs in a specific regime where the training set size is significantly larger than the number of dimensions but smaller than what's needed for direct interpolation. The study demonstrates that even with high empirical training error, methods like stochastic gradient descent (SGD) can achieve low test error in this "fourth quadrant" of prediction. AI
