A Deep Dive into Dataset Imbalance and Bias in Face Identification

no code implementations15 Mar 2022 Valeriia Cherepanova, Steven Reich, Samuel Dooley, Hossein Souri, Micah Goldblum, Tom Goldstein

This is an unfortunate omission, as 'imbalance' is a more complex matter in identification; imbalance may arise in not only the training data, but also the testing data, and furthermore may affect the proportion of identities belonging to each demographic group or the number of images belonging to each identity.

Plug-In Inversion: Model-Agnostic Inversion for Vision with Data Augmentations

1 code implementation31 Jan 2022 Amin Ghiasi, Hamid Kazemi, Steven Reich, Chen Zhu, Micah Goldblum, Tom Goldstein

Existing techniques for model inversion typically rely on hard-to-tune regularizers, such as total variation or feature regularization, which must be individually calibrated for each network in order to produce adequate images.

Ensemble Distillation for Structured Prediction: Calibrated, Accurate, Fast-Choose Three

no code implementations EMNLP 2020 Steven Reich, David Mueller, Nicholas Andrews

However, extending these methods to structured prediction is not always straightforward or effective; furthermore, a held-out calibration set may not always be available.
