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. Webberties for the exact solution of the considered problem, strong convergence analysis with sharp convergence rates for the proposed fully discrete scheme is rigorously established.

Webb6 feb. 2015 · With country fixed effects, the estimated convergence rate is misleadingly high. With data starting in 1870, country fixed effects are reasonable and the estimated convergence rate is 2.6%. Combining the two estimates suggests conditional convergence close to the ‘iron-law’ rate of 2%. Webb24 okt. 2008 · Rate of convergence in the law of large numbers in banach spaces.
