A Space-Time Transformer for Precipitation Forecasting

Accurate precipitation forecasting is increasingly crucial due to climate change. Recent machine learning approaches have emerged as alternatives to traditional methods like numerical weather prediction. However, many of these methods still use standard loss functions, which may not perform well during prolonged dry spells when precipitation is below the threshold. To overcome this issue, a new advanced torrential (AT) loss function is introduced, formulated as a quadratic unconstrained binary optimization (QUBO), which aims to enhance forecasting accuracy.
