On Optimal Set Estimation for Partially Identified Binary Choice Models

no code implementations3 Oct 2023 Shakeeb Khan, Tatiana Komarova, Denis Nekipelov

We illustrate the general problem in the context of a semiparametric binary choice model with discrete covariates as an example of a model which is partially identified as shown in, e. g. Bierens and Hartog (1988).

How Bad is Top-$K$ Recommendation under Competing Content Creators?

no code implementations3 Feb 2023 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

Content creators compete for exposure on recommendation platforms, and such strategic behavior leads to a dynamic shift over the content distribution.

Learning from a Learning User for Optimal Recommendations

no code implementations3 Feb 2022 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

In real-world recommendation problems, especially those with a formidably large item space, users have to gradually learn to estimate the utility of any fresh recommendations from their experience about previously consumed items.

Learning the Optimal Recommendation from Explorative Users

no code implementations6 Oct 2021 Fan Yao, Chuanhao Li, Denis Nekipelov, Hongning Wang, Haifeng Xu

We propose a new problem setting to study the sequential interactions between a recommender system and a user.

Identification and Formal Privacy Guarantees

no code implementations25 Jun 2020 Tatiana Komarova, Denis Nekipelov

We show that identification becomes possible if the target parameter can be deterministically located within the random set.

Global Concavity and Optimization in a Class of Dynamic Discrete Choice Models

no code implementations ICML 2020 Yiding Feng, Ekaterina Khmelnitskaya, Denis Nekipelov

Discrete choice models with unobserved heterogeneity are commonly used Econometric models for dynamic Economic behavior which have been adopted in practice to predict behavior of individuals and firms from schooling and job choices to strategic decisions in market competition.

Regularized Orthogonal Machine Learning for Nonlinear Semiparametric Models

3 code implementations13 Jun 2018 Denis Nekipelov, Vira Semenova, Vasilis Syrgkanis

This paper proposes a Lasso-type estimator for a high-dimensional sparse parameter identified by a single index conditional moment restriction (CMR).

Welfare Guarantees from Data

no code implementations NeurIPS 2017 Darrell Hoy, Denis Nekipelov, Vasilis Syrgkanis

The notion of the price of anarchy takes a worst-case stance to efficiency analysis, considering instance independent guarantees of efficiency.
