Rectifying Group Irregularities in Explanations for Distribution Shift

no code implementations25 May 2023 Adam Stein, Yinjun Wu, Eric Wong, Mayur Naik

It is well-known that real-world changes constituting distribution shift adversely affect model performance.

Do Machine Learning Models Learn Statistical Rules Inferred from Data?

1 code implementation2 Mar 2023 Aaditya Naik, Yinjun Wu, Mayur Naik, Eric Wong

Test-time adaptation reduces these violations by up to 68. 7% with relative performance improvement up to 32%.

Learning to Select Pivotal Samples for Meta Re-weighting

1 code implementation9 Feb 2023 Yinjun Wu, Adam Stein, Jacob Gardner, Mayur Naik

In this paper, we study how to learn to identify such a meta sample set from a large, imperfect training set, that is subsequently cleaned and used to optimize performance in the meta re-weighting setting.

CHEF: A Cheap and Fast Pipeline for Iteratively Cleaning Label Uncertainties (Technical Report)

1 code implementation19 Jul 2021 Yinjun Wu, James Weimer, Susan B. Davidson

First, to reduce the cost of human annotators, we use Infl, which prioritizes the most influential training samples for cleaning and provides cleaned labels to save the cost of one human annotator.

Dynamic Gaussian Mixture based Deep Generative Model For Robust Forecasting on Sparse Multivariate Time Series

1 code implementation3 Mar 2021 Yinjun Wu, Jingchao Ni, Wei Cheng, Bo Zong, Dongjin Song, Zhengzhang Chen, Yanchi Liu, Xuchao Zhang, Haifeng Chen, Susan Davidson

Forecasting on sparse multivariate time series (MTS) aims to model the predictors of future values of time series given their incomplete past, which is important for many emerging applications.

DeltaGrad: Rapid retraining of machine learning models

1 code implementation ICML 2020 Yinjun Wu, Edgar Dobriban, Susan B. Davidson

Machine learning models are not static and may need to be retrained on slightly changed datasets, for instance, with the addition or deletion of a set of data points.
