Adam: A Method for Stochastic Optimization

arxiv.org

paper is on the optimization of stochastic objectives with high-dimensional parameters spaces. In these cases, higher-order optimization methods are ill-suited, and discussion in this paper will be restricted to rst-order methods. We propose Adam , a method for efcient stochastic optimization that only requires rst-order gra-

Stochastic Gradient Descent Tricks

proposed Lasso algorithm represents each weight as the di erence of two positive variables. Applying the stochastic gradient rule to these variables and enforcing their positivity leads to sparser solutions. 2.3 The Convergence of Stochastic Gradient Descent The convergence of stochastic gradient descent has been studied extensively

Stochastic Calculus: An Introduction with Applications

www.math.uchicago.edu

We have used di erent fonts for the Eof conditional expectation and the E of usual expectation in order to emphasize that the conditional expectation is a random variable. However, most authors use the same font for both leaving it up to the reader …
