Cheap Bootstrap for Fast Uncertainty Quantification of Stochastic Gradient Descent

Apr 1, 2026arXiv Statistics — Machine Learning

Event Summary

arXiv:2310.11065v2 Announce Type: replace Abstract: Stochastic gradient descent (SGD) or stochastic approximation has been widely used in model training and stochastic optimization. While there is a huge literature on analyzing its convergence, inference on the obtained solutions from SGD has only b
