Learning from Viral Content

no code implementations3 Oct 2022 Krishna Dasaratha, Kevin He

We study learning on social media with an equilibrium model of users interacting with shared news stories.

KL-divergence Based Deep Learning for Discrete Time Model

no code implementations10 Aug 2022 Li Liu, Xiangeng Fang, Di Wang, Weijing Tang, Kevin He

Neural Network (Deep Learning) is a modern model in Artificial Intelligence and it has been exploited in Survival Analysis.

Observability, Dominance, and Induction in Learning Models

no code implementations3 Jan 2022 Daniel Clark, Drew Fudenberg, Kevin He

Learning models do not in general imply that weakly dominated strategies are irrelevant or justify the related concept of "forward induction," because rational agents may use dominated strategies as experiments to learn how opponents play, and may not have enough data to rule out a strategy that opponents never use.

Private Private Information

no code implementations29 Dec 2021 Kevin He, Fedor Sandomirskiy, Omer Tamuz

A private private information structure delivers information about an unknown state while preserving privacy: An agent's signal contains information about the state but remains independent of others' sensitive or private information.

Screening $p$-Hackers: Dissemination Noise as Bait

no code implementations16 Mar 2021 Federico Echenique, Kevin He

Uninformed $p$-hackers, who are fully ignorant of the true mechanism and engage in data mining, often fall for baits.

Evolutionarily Stable (Mis)specifications: Theory and Applications

no code implementations30 Dec 2020 Kevin He, Jonathan Libgober

Toward explaining the persistence of biased inferences, we propose a framework to evaluate competing (mis)specifications in strategic settings.

Aggregative Efficiency of Bayesian Learning in Networks

no code implementations22 Nov 2019 Krishna Dasaratha, Kevin He

In a class of networks where agents move in generations and observe the previous generation, we quantify the information loss with an aggregative efficiency index.

An Experiment on Network Density and Sequential Learning

no code implementations5 Sep 2019 Krishna Dasaratha, Kevin He

A network determines the observable predecessors, and we compare subjects' accuracy on sparse and dense networks.

Dynamic Information Design with Diminishing Sensitivity Over News

no code implementations31 Jul 2019 Jetlir Duraj, Kevin He

Diminishing sensitivity induces a preference over news skewness: gradual bad news, one-shot good news is worse than one-shot resolution, which is in turn worse than gradual good news, one-shot bad news.

Covariance-Insured Screening

no code implementations17 May 2018 Kevin He, Jian Kang, Hyokyoung Grace Hong, Ji Zhu, Yanming Li, Huazhen Lin, Han Xu, Yi Li

Modern bio-technologies have produced a vast amount of high-throughput data with the number of predictors far greater than the sample size.

Mislearning from Censored Data: The Gambler's Fallacy and Other Correlational Mistakes in Optimal-Stopping Problems

no code implementations21 Mar 2018 Kevin He

When agents wrongly expect systematic reversals (the "gambler's fallacy"), they understate the likelihood of consecutive below-average draws, converge to over-pessimistic beliefs about the distribution's mean, and stop too early.

Classification with Ultrahigh-Dimensional Features

no code implementations4 Nov 2016 Yanming Li, Hyokyoung Hong, Jian Kang, Kevin He, Ji Zhu, Yi Li

Although much progress has been made in classification with high-dimensional features \citep{Fan_Fan:2008, JGuo:2010, CaiSun:2014, PRXu:2014}, classification with ultrahigh-dimensional features, wherein the features much outnumber the sample size, defies most existing work.
