Influence Maximization with Fairness at Scale (Extended Version)

no code implementations2 Jun 2023 Yuting Feng, Ankitkumar Patel, Bogdan Cautis, Hossein Vahabi

In this paper, we revisit the problem of influence maximization with fairness, which aims to select k influential nodes to maximise the spread of information in a network, while ensuring that selected sensitive user attributes are fairly affected, i. e., are proportionally similar between the original network and the affected users.

SunCast: Solar Irradiance Nowcasting from Geosynchronous Satellite Data

no code implementations17 Jan 2022 Dhileeban Kumaresan, Richard Wang, Ernesto Martinez, Richard Cziva, Alberto Todeschini, Colorado J Reed, Hossein Vahabi

Accurate short-term PV power prediction enables operators to maximize the amount of power obtained from PV panels and safely reduce the reserve energy needed from fossil fuel sources.

HyperionSolarNet: Solar Panel Detection from Aerial Images

1 code implementation6 Jan 2022 Poonam Parhar, Ryan Sawasaki, Alberto Todeschini, Colorado Reed, Hossein Vahabi, Nathan Nusaputra, Felipe Vergara

The energy sector is the single largest contributor to climate change and many efforts are focused on reducing dependence on carbon-emitting power plants and moving to renewable energy sources, such as solar power.

Revenue Maximization of Airbnb Marketplace using Search Results

no code implementations14 Nov 2019 Jiawei Wen, Hossein Vahabi, Mihajlo Grbovic

The initial output of the pricing strategy is a price vector for the top displayed items in one search event.

Hierarchical Modeling and Shrinkage for User Session Length Prediction in Media Streaming

no code implementations4 Mar 2018 Antoine Dedieu, Rahul Mazumder, Zhen Zhu, Hossein Vahabi

In this work we present a novel framework inspired by hierarchical Bayesian modeling to predict, at the moment of login, the amount of time a user will spend in the streaming service.

Predicting Audio Advertisement Quality

no code implementations9 Feb 2018 Samaneh Ebrahimi, Hossein Vahabi, Matthew Prockup, Oriol Nieto

In these platforms, which tend to host tens of thousands of unique audio advertisements (ads), providing high quality ads ensures a better user experience and results in longer user engagement.

Predicting Session Length in Media Streaming

no code implementations1 Aug 2017 Theodore Vasiloudis, Hossein Vahabi, Ross Kravitz, Valery Rashkov

Session length is a very important aspect in determining a user's satisfaction with a media streaming service.

Scheduling Survival Analysis

Sequential ranking under random semi-bandit feedback

no code implementations4 Mar 2016 Hossein Vahabi, Paul Lagrée, Claire Vernade, Olivier Cappé

In many web applications, a recommendation is not a single item suggested to a user but a list of possibly interesting contents that may be ranked in some contexts.

A Hierarchical Recurrent Encoder-Decoder For Generative Context-Aware Query Suggestion

4 code implementations8 Jul 2015 Alessandro Sordoni, Yoshua Bengio, Hossein Vahabi, Christina Lioma, Jakob G. Simonsen, Jian-Yun Nie

Our novel hierarchical recurrent encoder-decoder architecture allows the model to be sensitive to the order of queries in the context while avoiding data sparsity.
