摘要:

In machine learning-driven landslide prediction models, data quality directly determines the accuracy of landslide predictions. Currently, data preprocessing methods mainly involve fitting the data using moving averages or least squares methods. While these methods are effective and convenient for processing global data, they face limitations when dealing with local data during heavy rainfall events. The sharp increase in cumulative landslide displacement during significant rainfall makes it challenging for overall data preprocessing methods to effectively handle local data, leading to potential data loss and compromising data quality. To address this limitation, this paper proposes a segmented data processing approach. During periods of heavy rainfall, cubic spline interpolation is employed to interpolate missing data, providing a better representation of data variability. For smaller rainfall amounts, linear interpolation is utilized. Finally, the LOESS smoothing method is applied to further enhance data quality. These meticulous data processing steps aim to accurately capture the changing trends in rainfall-induced landslides. By providing more reliable inputs to machine learning prediction models, this approach seeks to improve the accuracy and reliability of landslide predictions. © 2024 IEEE.
