Classification of Intracellular Protein Patterns from Reactive Equilibria
Henrik Weyer, Ching Yee Leung, Erwin Frey
Self-organized spatial patterns are central to nonequilibrium physics and cell biology, yet locating instabilities in multi-component, reaction-diffusion networks remains challengi…
Regression Adjustments for Double Randomization in Two-Sided Marketplaces
Timothy Sudijono, Lihua Lei, Lorenzo Masoero +3
Multiple randomization designs (MRDs) are a class of experimental designs used to handle interference in two-sided marketplaces. We investigate regression adjustment strategies for…
Compound Selection Decisions: An Almost SURE Approach
Jiafeng Chen, Lihua Lei, Timothy Sudijono +2
This paper proposes methods for producing compound selection decisions in a Gaussian sequence model. Given unknown, fixed parameters and known with observati…
Neural Networks Generalize on Low Complexity Data
Sourav Chatterjee, Timothy Sudijono
We show that feedforward neural networks with ReLU activation generalize on low complexity data, suitably defined. Given i.i.d.~data generated from a simple programming language, t…
Non-identifiability distinguishes Neural Networks among Parametric Models
Sourav Chatterjee, Timothy Sudijono
One of the enduring problems surrounding neural networks is to identify the factors that differentiate them from traditional statistical models. We prove a pair of results which di…
Inference for Synthetic Controls via Refined Placebo Tests
Lihua Lei, Timothy Sudijono
The synthetic control method is often applied to problems with one treated unit and a small number of control units. A common inferential task in this setting is to test null hypot…
