PlumeCityNet: Multi-Resolution Air Quality Forecasting

no code implementations6 Oct 2021 Thibaut Cassard, Grégoire Jauvion, Antoine Alléon, Boris Quennehen, David Lissmyr

Then, the engine is based on a U-Net architecture built with several of those blocks, giving it the ability to process inputs and to output predictions at different resolutions.

High-Resolution Air Quality Prediction Using Low-Cost Sensors

no code implementations22 Jun 2020 Thibaut Cassard, Grégoire Jauvion, David Lissmyr

An other strong conclusion is that in some areas with a high density of low-cost sensors, the engine performs better when fed with low-cost sensors' measurements only than when fed with official monitoring stations' measurements only: this suggests that an air quality monitoring network composed of low-cost sensors is effective in monitoring air quality.

PlumeNet: Large-Scale Air Quality Forecasting Using A Convolutional LSTM Network

no code implementations14 Jun 2020 Antoine Alléon, Grégoire Jauvion, Boris Quennehen, David Lissmyr

This paper presents an engine able to forecast jointly the concentrations of the main pollutants harming people's health: nitrogen dioxyde (NO2), ozone (O3) and particulate matter (PM2. 5 and PM10, which are respectively the particles whose diameters are below 2. 5 um and 10 um respectively).

Real-Time Optimization Of Web Publisher RTB Revenues

no code implementations12 Jun 2020 Pedro Chahuara, Nicolas Grislain, Grégoire Jauvion, Jean-Michel Renders

The real-world challenges we had to tackle consist mainly of tracking the dependencies on both the user and placement in an highly non-stationary environment and of dealing with censored bid observations.

Optimal Allocation of Real-Time-Bidding and Direct Campaigns

no code implementations12 Jun 2020 Grégoire Jauvion, Nicolas Grislain

The optimal strategy gives a formula to determine the publisher bid as well as a way to choose the direct campaign being delivered if the publisher bidder wins the auction, depending on the impression characteristics.

DeepPlume: Very High Resolution Real-Time Air Quality Mapping

no code implementations14 Feb 2020 Grégoire Jauvion, Thibaut Cassard, Boris Quennehen, David Lissmyr

Plume Labs has deployed a similar prediction engine to build several products aiming at providing air quality data to individuals and businesses.

Optimization of a SSP's Header Bidding Strategy using Thompson Sampling

no code implementations9 Jul 2018 Grégoire Jauvion, Nicolas Grislain, Pascal Sielenou Dkengne, Aurélien Garivier, Sébastien Gerchinovitz

The SSP acts as an intermediary between an advertiser wanting to buy ad spaces and a web publisher wanting to sell its ad spaces, and needs to define a bidding strategy to be able to deliver to the advertisers as many ads as possible while spending as little as possible.
