Geometry-Aware InSAR Feedback Purification Sampling for Negative Sample Selection in Landslide Susceptibility Assessment: A Case Study in the Shigatse Region

This repository contains the supplementary data and reproducibility materials for the GIFPS study on negative-sample selection in landslide susceptibility assessment. It includes the analysis code, experimental settings, derived geospatial data, representative candidate-pool raster, numerical results, and the following supplementary tables: Table S1. Hyperparameter search ranges. Table S2. Performance comparison of BCS, DOLIS, and GIFPS under different buffer distances. Values are means (standard deviations) across 30 independent repetitions. Table S3. Sensitivity of GIFPS to alternative low-deformation threshold definitions at the 1000 m buffer distance. Values are means (standard deviations) across 30 independent repetitions.
