提出GMG模型,提升气象视频预测中长距离依赖与非刚性运动的捕捉能力。

GMG: A Video Prediction Method Based on Global Focus and Motion Guided

  • 引入全局聚焦模块扩大感受野,增强长程依赖建模
  • 设计运动引导模块适应非刚性体的形变演化过程
  • 在复杂气象任务中表现优异,适合高动态时空数据预测

近年来,气象预报受到广泛关注。然而,由于气象数据变化迅速且存在潜在遥相关,准确预测仍具挑战。现有时空预测模型主要依赖卷积或滑动窗口进行特征提取,受限于卷积核或窗口大小,难以捕捉气象数据中的潜在遥相关特征。此外,气象数据常涉及非刚性体,其运动伴随不可预测的形变,进一步增加预测难度。本文提出GMG模型,解决上述两大核心问题。其中,全局聚焦模块扩展了全局感受野;运动引导模块则能适应非刚性体的增长或消散过程。通过大量实验验证,该方法在多种复杂任务中表现出色,为提升复杂时空数据预测精度提供了新思路。

原文摘要 · Abstract (English)

Recent years, weather forecasting has gained significant attention. However, accurately predicting weather remains a challenge due to the rapid variability of meteorological data and potential teleconnections. Current spatiotemporal forecasting models primarily rely on convolution operations or sliding windows for feature extraction. These methods are limited by the size of the convolutional kernel or sliding window, making it difficult to capture and identify potential teleconnection features in meteorological data. Additionally, weather data often involve non-rigid bodies, whose motion processes are accompanied by unpredictable deformations, further complicating the forecasting task. In this paper, we propose the GMG model to address these two core challenges. The Global Focus Module, a key component of our model, enhances the global receptive field, while the Motion Guided Module adapts to the growth or dissipation processes of non-rigid bodies. Through extensive evaluations, our method demonstrates competitive performance across various complex tasks, providing a novel approach to improving the predictive accuracy of complex spatiotemporal data.
