The Impact of Neural Network Overparameterization on Gradient Confusion and Stochastic Gradient Descent
2019 · arXiv (Cornell University)
This paper studies how neural network architecture affects the speed of training. We introduce a simple concept called gradient confusion to help formally analyze this. When gradient confusion is high, stochastic gradients produced by different …

Robust Identifiability in Linear Structural Equation Models of Causal Inference
2020 · arXiv (Cornell University)
In this work, we consider the problem of robust parameter estimation from observational data in the context of linear structural equation models (LSEMs). LSEMs are a popular and well-studied class of models for inferring causality …
