Implicit Regularization and Convergence for Weight Normalization

Xiaoxia Wu, Edgar Dobriban, Tongzheng Ren +5

Normalization methods such as batch [Ioffe and Szegedy, 2015], weight [Salimansand Kingma, 2016], instance [Ulyanov et al., 2016], and layer normalization [Baet al., 2016] have bee…

Linear Convergence of Adaptive Stochastic Gradient Descent

Yuege Xie, Xiaoxia Wu, Rachel Ward

We prove that the norm version of the adaptive stochastic gradient method (AdaGrad-Norm) achieves a linear convergence rate for a subset of either strongly convex functions or non-…

AdaOja: Adaptive Learning Rates for Streaming PCA

Amelia Henriksen, Rachel Ward

Oja's algorithm has been the cornerstone of streaming methods in Principal Component Analysis (PCA) since it was first proposed in 1982. However, Oja's algorithm does not have a st…
