Estimating Rationally Inattentive Utility Functions with Deep Clustering for Framing - Applications in YouTube Engagement Dynamics
William Hoiles, Vikram Krishnamurthy
We consider a framework involving behavioral economics and machine learning. Rationally inattentive Bayesian agents make decisions based on their posterior distribution, utility fu…
Information Diffusion in Social Networks: Friendship Paradox based Models and Statistical Inference
Vikram Krishnamurthy, Buddhika Nettasinghe
Dynamic models and statistical inference for the diffusion of information in social networks is an area which has witnessed remarkable progress in the last decade due to the prolif…
Contagions in Social Networks: Effects of Monophilic Contagion, Friendship Paradox and Reactive Networks
Buddhika Nettasinghe, Vikram Krishnamurthy, Kristina Lerman
We consider SIS contagion processes over networks where, a classical assumption is that individuals' decisions to adopt a contagion are based on their immediate neighbors. However,…
Adaptive Polling in Hierarchical Social Networks using Blackwell Dominance
Sujay Bhatt, Vikram Krishnamurthy
Consider a population of individuals that observe an underlying state of nature that evolves over time. The population is classified into different levels depending on the hierarch…
New Sufficient Conditions for Lower Bounding the Optimal Policy of a POMDP using Lehmann Precision
Vikram Krishnamurthy
This paper provides new sufficient conditions so that the optimal policy of a partially observed Markov decision process (POMDP) can be lower bounded by a myopic policy. The two ne…
What Do Your Friends Think? Efficient Polling Methods for Networks Using Friendship Paradox
Buddhika Nettasinghe, Vikram Krishnamurthy
This paper deals with randomized polling of a social network. In the case of forecasting the outcome of an election between two candidates A and B, classical intent polling asks ra…
