AutoFT: Learning an Objective for Robust Fine-Tuning

no code implementations18 Jan 2024 Caroline Choi, Yoonho Lee, Annie Chen, Allan Zhou, aditi raghunathan, Chelsea Finn

Given a task, AutoFT searches for a fine-tuning procedure that enhances out-of-distribution (OOD) generalization.

Conservative Prediction via Data-Driven Confidence Minimization

1 code implementation8 Jun 2023 Caroline Choi, Fahim Tajwar, Yoonho Lee, Huaxiu Yao, Ananya Kumar, Chelsea Finn

Taking inspiration from this result, we present data-driven confidence minimization (DCM), which minimizes confidence on an uncertainty dataset containing examples that the model is likely to misclassify at test time.

Wild-Time: A Benchmark of in-the-Wild Distribution Shift over Time

1 code implementation25 Nov 2022 Huaxiu Yao, Caroline Choi, Bochuan Cao, Yoonho Lee, Pang Wei Koh, Chelsea Finn

Temporal shifts -- distribution shifts arising from the passage of time -- often occur gradually and have the additional structure of timestamp metadata.
