Learning Spatio-Temporal Correlations from Dynamic and Sparse Data
The amount of spatio-temporal measurements around Earth, its atmosphere, in human-made urban settings, and in its oceans increases with affordable and smaller sensor technologies. Improved communication technologies allow sensors to be not geostationary, changing their positions and measurement …

The spectral characteristics of wind-farm power output
… holistic, physics-based approach to modeling the spatio-temporal structures of the atmospheric boundary layer, and the ways in which these structures impart themselves in wind-power variability. The following primary findings are presented. Field and laboratory experiments were performed to unravel …

Energy Efficient Deep Spiking Recurrent Neural Networks: A Reservoir Computing-Based Approach
… pattern recognition and exploring the underlying spatio-temporal correlation. However, due to the vanishing/exploding gradient problem, training a fully connected RNN in many cases is very difficult or even impossible. The difficulties of training traditional RNNs, led us to reservoir computing …
