TCT: Convexifying Federated Learning using Bootstrapped Neural Tangent Kernels

1 code implementation13 Jul 2022 Yaodong Yu, Alexander Wei, Sai Praneeth Karimireddy, Yi Ma, Michael I. Jordan

Leveraging this observation, we propose a Train-Convexify-Train (TCT) procedure to sidestep this issue: first, learn features using off-the-shelf methods (e. g., FedAvg); then, optimize a convexified problem obtained from the network's empirical neural tangent kernel approximation.

More Than a Toy: Random Matrix Models Predict How Real-World Neural Representations Generalize

no code implementations11 Mar 2022 Alexander Wei, Wei Hu, Jacob Steinhardt

On the other hand, we find that the classical GCV estimator (Craven and Wahba, 1978) accurately predicts generalization risk even in such overparameterized settings.

Predicting Out-of-Distribution Error with the Projection Norm

1 code implementation11 Feb 2022 Yaodong Yu, Zitong Yang, Alexander Wei, Yi Ma, Jacob Steinhardt

Projection Norm first uses model predictions to pseudo-label test samples and then trains a new model on the pseudo-labels.

Learning Equilibria in Matching Markets from Bandit Feedback

no code implementations NeurIPS 2021 Meena Jagadeesan, Alexander Wei, Yixin Wang, Michael I. Jordan, Jacob Steinhardt

Large-scale, two-sided matching platforms must find market outcomes that align with user preferences while simultaneously learning these preferences from data.
