Understanding Adam Requires Better Rotation Dependent Assumptions

Tianyue H. Zhang, Lucas Maes, Alan Milligan +5

Despite its widespread adoption, Adam's advantage over Stochastic Gradient Descent (SGD) lacks a comprehensive theoretical explanation. This paper investigates Adam's sensitivity t…

An Empirical Study of Pre-trained Model Selection for Out-of-Distribution Generalization and Calibration

Hiroki Naganuma, Ryuichiro Hataya, Kotaro Yoshida +1

In the field of computer vision, fine-tuning pre-trained models has become a prevalent strategy for out-of-distribution (OOD) generalization tasks. Different from most prior work t…

Performative Prediction with Neural Networks

Mehrnaz Mofakhami, Ioannis Mitliagkas, Gauthier Gidel

Performative prediction is a framework for learning models that influence the data they intend to predict. We focus on finding classifiers that are performatively stable, i.e. opti…

Towards efficient representation identification in supervised learning

Kartik Ahuja, Divyat Mahajan, Vasilis Syrgkanis +1

Humans have a remarkable ability to disentangle complex sensory inputs (e.g., image, text) into simple factors of variation (e.g., shape, color) without much supervision. This abil…

Expecting The Unexpected: Towards Broad Out-Of-Distribution Detection

Charles Guille-Escuret, Pierre-André Noël, Ioannis Mitliagkas +2

Improving the reliability of deployed machine learning systems often involves developing methods to detect out-of-distribution (OOD) inputs. However, existing research often narrow…
