Webb10 aug. 2024 · However, vanilla SGD suffers from slow convergence, and its performance is sensitive to the learning rate—which is tricky to tune. Many techniques have been introduced to improve the convergence speed and robustness of SGD, such as variance reduction . defazio2014saga; johnson2013accelerating; nguyen2024sarah, adaptive … Webb1 feb. 2024 · Abstract: This paper provides sharp rates of convergence of the gradient descent (GD) method for deep linear neural networks with different random initialization. This study touches upon one major open theoretical problem in machine learning: why deep neural networks trained with GD methods are efficient in many practical applications.

Furthermore, for (ii), we show that elastic-net MKL can outperform block-ℓ 1 MKL and block-ℓ 2 MKL depending on the sparsity of the truth and the condition of the problem.
