RAP-Net: Region Attention Predictive Network for precipitation nowcasting

چکیده

Abstract. Natural disasters caused by heavy rainfall often cause huge loss of life and property. Hence, the task precipitation nowcasting is great importance. To solve this problem, several deep learning methods have been proposed to forecast future radar echo images, then predicted maps are converted distribution rainfall. The prevailing spatiotemporal sequence prediction apply a ConvRNN structure, which combines convolution recurrent neural network. Although achieve remarkable success, they do not capture both local global spatial features simultaneously, degrades in regions address issue, we propose Region Attention Block (RAB) embed it into enhance forecasting areas with Besides, models find hard memorize longer historical representations limited parameters. end, Recall Mechanism (RAM) improve prediction. By preserving temporal information, RAM contributes forecasting, especially moderate intensity. experiments show that model, Predictive Network (RAP-Net), significantly outperforms state-of-the-art methods.

Convolutional LSTM Network: A Machine Learning Approach for Precipitation Nowcasting

The goal of precipitation nowcasting is to predict the future rainfall intensity in a local region over a relatively short period of time. Very few previous studies have examined this crucial and challenging weather forecasting problem from the machine learning perspective. In this paper, we formulate precipitation nowcasting as a spatiotemporal sequence forecasting problem in which both the in...

Artificial neural-network technique for precipitation nowcasting from satellite imagery

The term nowcasting reflects the need of timely and accurate predictions of risky situations related to the development of severe meteorological events. In this work the objective is the very short term prediction of the rainfall field from geostationary satellite imagery entirely based on neural network approach. The very short-time prediction (or nowcasting) process consists of two steps: fir...

Characterizing Attention with Predictive Network Models.

Recent work shows that models based on functional connectivity in large-scale brain networks can predict individuals' attentional abilities. While being some of the first generalizable neuromarkers of cognitive function, these models also inform our basic understanding of attention, providing empirical evidence that: (i) attention is a network property of brain computation; (ii) the functional ...
