AI总结:

针对降雨预测中存在的地域分布偏移与天气模式随时间变化的问题,提出一种自适应深度学习框架,可实现跨地点的泛化降雨预测,在三座城市的实验中均取得显著性能提升。

摘要:

降雨预测是一项具有挑战性的任务,因为它依赖于随地理位置不同而变化的天气与气象特征。因此,在某一地点表现良好的预测模型会因分布偏移而在其他地点表现不佳。此外,受全球变暖影响,天气模式正逐年快速变化,这导致即便在同一地点,这类模型也可能随着时间推移失效。在本研究中,我们提出了一种基于自适应深度学习的框架,以解决上述挑战。我们的方法能够让模型泛化至任意地点的降雨预测,而无自适应能力的方法在这类场景下会失效。在使用深度神经网络进行自适应调整后,我们的方法在巴黎、洛杉矶和东京的降雨预测任务中,性能分别提升了43.51%、5.09%和38.62%。

英文摘要:

Rain precipitation prediction is a challenging task as it depends on weather and meteorological features which vary from location to location. As a result, a prediction model that performs well at one location does not perform well at other locations due to the distribution shifts. In addition, due to global warming, the weather patterns are changing very rapidly year by year which creates the possibility of ineffectiveness of those models even at the same location as time passes. In our work, we have proposed an adaptive deep learning-based framework in order to provide a solution to the aforementioned challenges. Our method can generalize the model for the prediction of precipitation for any location where the methods without adaptation fail. Our method has shown 43.51%, 5.09%, and 38.62% improvement after adaptation using a deep neural network for predicting the precipitation of Paris, Los Angeles, and Tokyo, respectively.
