In recent years, machine learning-based cardinality estimation methods are replacing traditional methods.

Scaling Private Deep Learning with Low-Rank and Sparse Gradients

no code implementations6 Jul 2022 Ryuichi Ito, Seng Pei Liew, Tsubasa Takahashi, Yuya Sasaki, Makoto Onizuka

Applying Differentially Private Stochastic Gradient Descent (DPSGD) to training modern, large-scale neural networks such as transformer-based models is a challenging task, as the magnitude of noise added to the gradients at each iteration scales with model dimension, hindering the learning capability significantly.
