Online Algorithms with Limited Data Retention

no code implementations17 Apr 2024 Nicole Immorlica, Brendan Lucier, Markus Mobius, James Siderius

We also show a nearly matching lower bound on the retention required to guarantee error $\epsilon$.

Impact of Decentralized Learning on Player Utilities in Stackelberg Games

no code implementations29 Feb 2024 Kate Donahue, Nicole Immorlica, Meena Jagadeesan, Brendan Lucier, Aleksandrs Slivkins

To better understand such cases, we examine the learning dynamics of the two-agent system and the implications for each agent's objective.

Chatbot Recommendation Systems

Clickbait vs. Quality: How Engagement-Based Optimization Shapes the Content Landscape in Online Platforms

no code implementations18 Jan 2024 Nicole Immorlica, Meena Jagadeesan, Brendan Lucier

To understand the total impact on the content landscape, we study a game between content creators competing on the basis of engagement metrics and analyze the equilibrium decisions about investment in quality and gaming.

Algorithmic Persuasion Through Simulation

no code implementations29 Nov 2023 Keegan Harris, Nicole Immorlica, Brendan Lucier, Aleksandrs Slivkins

After a fixed number of queries, the sender commits to a messaging policy and the receiver takes the action that maximizes her expected utility given the message she receives.

Efficiency in Collective Decision-Making via Quadratic Transfers

no code implementations15 Jan 2023 Jon X. Eguia, Nicole Immorlica, Steven P. Lalley, Katrina Ligett, Glen Weyl, Dimitrios Xefteris

Consider the following collective choice problem: a group of budget constrained agents must choose one of several alternatives.

Decision Making

Content Filtering with Inattentive Information Consumers

no code implementations27 May 2022 Ian Ball, James Bono, Justin Grana, Nicole Immorlica, Brendan Lucier, Aleksandrs Slivkins

We develop a model of content filtering as a game between the filter and the content consumer, where the latter incurs information costs for examining the content.

Misinformation Recommendation Systems

Communicating with Anecdotes

no code implementations26 May 2022 Nika Haghtalab, Nicole Immorlica, Brendan Lucier, Markus Mobius, Divyarthi Mohan

We study a communication game between a sender and receiver where the sender has access to a set of informative signals about a state of the world.

Social Learning under Platform Influence: Consensus and Persistent Disagreement

no code implementations25 Feb 2022 Ozan Candogan, Nicole Immorlica, Bar Light, Jerry Anunrojwong

In this paper, we introduce an opinion dynamics model where agents are connected in a social network, and update their opinions based on their neighbors' opinions and on the content shown to them by the platform.

Stochastic Block Model

Making Auctions Robust to Aftermarkets

no code implementations13 Jul 2021 Moshe Babaioff, Nicole Immorlica, Yingkai Li, Brendan Lucier

We show that when using balanced prices, both these approaches ensure high equilibrium welfare in the combined market.

Dynamic Weighted Matching with Heterogeneous Arrival and Departure Rates

no code implementations1 Dec 2020 Natalie Collina, Nicole Immorlica, Kevin Leyton-Brown, Brendan Lucier, Neil Newman

The value of a match is determined by the types of the matched agents.

Maximizing Welfare with Incentive-Aware Evaluation Mechanisms

no code implementations3 Nov 2020 Nika Haghtalab, Nicole Immorlica, Brendan Lucier, Jack Z. Wang

The goal is to design an evaluation mechanism that maximizes the overall quality score, i. e., welfare, in the population, taking any strategic updating into account.

Bayesian Exploration with Heterogeneous Agents

no code implementations19 Feb 2019 Nicole Immorlica, Jieming Mao, Aleksandrs Slivkins, Zhiwei Steven Wu

We consider Bayesian Exploration: a simple model in which the recommendation system (the "principal") controls the information flow to the users (the "agents") and strives to incentivize exploration via information asymmetry.

Recommendation Systems

Adversarial Bandits with Knapsacks

no code implementations28 Nov 2018 Nicole Immorlica, Karthik Abinav Sankararaman, Robert Schapire, Aleksandrs Slivkins

We suggest a new algorithm for the stochastic version, which builds on the framework of regret minimization in repeated games and admits a substantially simpler analysis compared to prior work.

Multi-Armed Bandits Scheduling

The Disparate Effects of Strategic Manipulation

no code implementations27 Aug 2018 Lily Hu, Nicole Immorlica, Jennifer Wortman Vaughan

When consequential decisions are informed by algorithmic input, individuals may feel compelled to alter their behavior in order to gain a system's approval.

General Classification

Unleashing Linear Optimizers for Group-Fair Learning and Optimization

no code implementations11 Apr 2018 Daniel Alabi, Nicole Immorlica, Adam Tauman Kalai

Most systems and learning algorithms optimize average performance or average loss -- one reason being computational complexity.

Fairness

Decoupled classifiers for fair and efficient machine learning

no code implementations20 Jul 2017 Cynthia Dwork, Nicole Immorlica, Adam Tauman Kalai, Max Leiserson

When it is ethical and legal to use a sensitive attribute (such as gender or race) in machine learning systems, the question remains how to do so.
