Trade-off Between Dependence and Complexity for Nonparametric Learning -- an Empirical Process Approach

no code implementations17 Jan 2024 Nabarun Deb, Debarghya Mukherjee

Our main result shows that a non-trivial trade-off between the complexity of the underlying function class and the dependence among the observations characterizes the learning rate in a large class of nonparametric problems.

Deep Neural Networks for Nonparametric Interaction Models with Diverging Dimension

no code implementations12 Feb 2023 Sohom Bhattacharya, Jianqing Fan, Debarghya Mukherjee

We show that under certain standard assumptions, debiased deep neural networks achieve a minimax optimal rate both in terms of $(n, d)$.

Predictor-corrector algorithms for stochastic optimization under gradual distribution shift

1 code implementation26 May 2022 Subha Maity, Debarghya Mukherjee, Moulinath Banerjee, Yuekai Sun

Time-varying stochastic optimization problems frequently arise in machine learning practice (e. g. gradual domain shift, object tracking, strategic classification).

Domain Adaptation meets Individual Fairness. And they get along

no code implementations1 May 2022 Debarghya Mukherjee, Felix Petersen, Mikhail Yurochkin, Yuekai Sun

In this paper, we leverage this connection between algorithmic fairness and distribution shifts to show that algorithmic fairness interventions can help ML models overcome distribution shifts, and that domain adaptation methods (for overcoming distribution shifts) can mitigate algorithmic biases.

Estimation of a score-explained non-randomized treatment effect in fixed and high dimensions

no code implementations22 Feb 2021 Debarghya Mukherjee, Moulinath Banerjee, Ya'acov Ritov

In this paper, we present a new model coined SCENTS: Score Explained Non-Randomized Treatment Systems, and a corresponding method that allows estimation of the treatment effect at $\sqrt{n}$ rate in the presence of fairly general forms of confoundedness, when the `score' variable on whose basis treatment is assigned can be explained via certain feature measurements of the individuals under study.

There is no trade-off: enforcing fairness can improve accuracy

no code implementations28 Sep 2020 Subha Maity, Debarghya Mukherjee, Mikhail Yurochkin, Yuekai Sun

If the algorithmic biases in an ML model are due to sampling biases in the training data, then enforcing algorithmic fairness may improve the performance of the ML model on unbiased test data.

Two Simple Ways to Learn Individual Fairness Metrics from Data

no code implementations19 Jun 2020 Debarghya Mukherjee, Mikhail Yurochkin, Moulinath Banerjee, Yuekai Sun

Individual fairness is an intuitive definition of algorithmic fairness that addresses some of the drawbacks of group fairness.
