Performative Prediction with Bandit Feedback: Learning through Reparameterization

no code implementations1 May 2023 Yatong Chen, Wei Tang, Chien-Ju Ho, Yang Liu

Specifically, we develop a {\em reparameterization} framework that reparametrizes the performative prediction objective as a function of the induced data distribution.

Tier Balancing: Towards Dynamic Fairness over Underlying Causal Factors

1 code implementation21 Jan 2023 Zeyu Tang, Yatong Chen, Yang Liu, Kun Zhang

The pursuit of long-term fairness involves the interplay between decision-making and the underlying data generating process.

Metric-Fair Classifier Derandomization

no code implementations15 Jun 2022 Jimmy Wu, Yatong Chen, Yang Liu

We study the problem of classifier derandomization in machine learning: given a stochastic binary classifier $f: X \to [0, 1]$, sample a deterministic classifier $\hat{f}: X \to \{0, 1\}$ that approximates the output of $f$ in aggregate over any data distribution.

Fairness Transferability Subject to Bounded Distribution Shift

1 code implementation31 May 2022 Yatong Chen, Reilly Raab, Jialu Wang, Yang Liu

Given an algorithmic predictor that is "fair" on some source distribution, will it still be fair on an unknown target distribution that differs from the source within some bound?

Model Transferability With Responsive Decision Subjects

1 code implementation13 Jul 2021 Yatong Chen, Zeyu Tang, Kun Zhang, Yang Liu

We provide both upper bounds for the performance gap due to the induced domain shift, as well as lower bounds for the trade-offs that a classifier has to suffer on either the source training distribution or the induced target distribution.

Linear Classifiers that Encourage Constructive Adaptation

no code implementations31 Oct 2020 Yatong Chen, Jialu Wang, Yang Liu

Machine learning systems are often used in settings where individuals adapt their features to obtain a desired outcome.
