Forecasting emissions through Kaya identity using Neural Ordinary Differential Equations

no code implementations7 Jan 2022 Pierre Browne, Aranildo Lima, Rossella Arcucci, César Quilodrán-Casas

Starting from the Kaya identity, we used a Neural ODE model to predict the evolution of several indicators related to carbon emissions, on a country-level: population, GDP per capita, energy intensity of GDP, carbon intensity of energy.

Adversarial autoencoders and adversarial LSTM for improved forecasts of urban air pollution simulations

1 code implementation13 Apr 2021 César Quilodrán-Casas, Rossella Arcucci, Laetitia Mottet, Yike Guo, Christopher Pain

Our two-step method integrates a Principal Components Analysis (PCA) based adversarial autoencoder (PC-AAE) with adversarial Long short-term memory (LSTM) networks.
