Counterbalancing Teacher: Regularizing Batch Normalized Models for Robustness

no code implementations29 Sep 2021 Saeid Asgari, Fereshte Khani, Ali Gholami, Kristy Choi, Linh Tran, Ran Zhang

Batch normalization (BN) is a ubiquitous technique for training deep neural networks that accelerates their convergence to reach higher accuracy.

AI is undergoing a paradigm shift with the rise of models (e. g., BERT, DALL-E, GPT-3) that are trained on broad data at scale and are adaptable to a wide range of downstream tasks.

In-N-Out: Pre-Training and Self-Training using Auxiliary Information for Out-of-Distribution Robustness

1 code implementation ICLR 2021 Sang Michael Xie, Ananya Kumar, Robbie Jones, Fereshte Khani, Tengyu Ma, Percy Liang

To get the best of both worlds, we introduce In-N-Out, which first trains a model with auxiliary inputs and uses it to pseudolabel all the in-distribution inputs, then pre-trains a model on OOD auxiliary outputs and fine-tunes this model with the pseudolabels (self-training).

Removing Spurious Features can Hurt Accuracy and Affect Groups Disproportionately

1 code implementation7 Dec 2020 Fereshte Khani, Percy Liang

The presence of spurious features interferes with the goal of obtaining robust models that perform well across many groups within the population.

Feature Noise Induces Loss Discrepancy Across Groups

1 code implementation ICML 2020 Fereshte Khani, Percy Liang

Our main result is that even when there is no information deficiency specific to one group (e. g., both groups have infinite data), adding the same amount of feature noise to all individuals leads to loss discrepancy.

Maximum Weighted Loss Discrepancy

1 code implementation8 Jun 2019 Fereshte Khani, aditi raghunathan, Percy Liang

To capture this inequality, we introduce and study a notion we call maximum weighted loss discrepancy (MWLD), the maximum (weighted) difference between the loss of a group and the loss of the population.

Planning, Inference and Pragmatics in Sequential Language Games

1 code implementation TACL 2018 Fereshte Khani, Noah D. Goodman, Percy Liang

We study sequential language games in which two players, each with private information, communicate to achieve a common goal.

Unanimous Prediction for 100% Precision with Application to Learning Semantic Mappings

1 code implementation20 Jun 2016 Fereshte Khani, Martin Rinard, Percy Liang

Specifically, we introduce the unanimity principle: only predict when all models consistent with the training data predict the same output.
