چکیده
Because of the impact extreme heat waves and domes on society biodiversity, their study is a key challenge. We specifically long-lasting waves, which are among most important for climate impacts. Physics driven weather forecast systems or models can be used to occurrence predict probability. The present work explores use deep learning architectures, trained using outputs model, as an alternative strategy heatwave. This new approach will useful several scientific goals include model statistics, building quantitative proxy resampling rare events in models, change, should eventually forecasting. Fulfilling these implies addressing issues such class-size imbalance that intrinsically associated with event prediction, assessing potential benefits transfer address nested nature (naturally included less ones). train Convolutional Neural Network, 1,000 years outputs, large-class undersampling learning. From observed snapshots surface temperature 500 hPa geopotential height fields, network achieves significant performance forecasting heatwaves. able them at three different levels intensity, early 15 days ahead start (30 end event).

Deep Forecast: Deep Learning-based Spatio-Temporal Forecasting
The paper presents a spatio-temporal wind speed forecasting algorithm using Deep Learning (DL) and in particular, Recurrent Neural Networks (RNNs). Motivated by recent advances in renewable energy integration and smart grids, we apply our proposed algorithm for wind speed forecasting. Renewable energy resources (wind and solar) are random in nature and, thus, their integration is facilitated wi...
متن کاملDeep Extreme Multi-label Learning
Extreme multi-label learning (XML) or classification has been a practical and important problem since the boom of big data. The main challenge lies in the exponential label space which involves 2 possible label sets when the label dimension L is very large, e.g., in millions for Wikipedia labels. This paper is motivated to better explore the label space by building and modeling an explicit labe...
