Webbwhere x2Rdis a vector representing the parameters (model weights, features) of a model we wish to train, nis the number of training data points, and f i(x) represents the (smooth) loss of the model xon data point i. The goal of ERM is to train a model whose average loss on the training data is minimized. This abstraction allows to encode ... Webb1 juni 2014 · We study the statistical properties of stochastic gradient descent (SGD) using explicit and im-plicit updates for fitting generalized linear mod-els (GLMs). Initially, we …

WebbSpecifically, [46, 29] analyze the linear stability [1] of SGD, showing that a linearly stable minimum must be flat and uniform. Different from SDE-based analysis, this stability … WebbBassily et al. (2014) analyzed the theoretical properties of DP-SGD for DP-ERM, and derived matching utility lower bounds. Faster algorithms based on SVRG (Johnson and Zhang,2013; ... In this section, we evaluate the practical performance of DP-GCD on linear models using the logistic and http://cbmm.mit.edu/sites/default/files/publications/CBMM-Memo-067-v3.pdf safe measures log in virginia
