English(EN) Deficit-Driven Stratified Acquisition for Building STRATA-S12: An Open SAR-Optical Corpus for Self-Supervised Learning

新算法改进了用于地球观测的SAR-光学语料库创建

研究人员开发了一种名为赤字驱动分层采集(DDSA)的新算法,以应对构建用于自监督地球观测的共配准SAR-光学语料库所面临的挑战。与机会性数据收集不同,DDSA将语料库构建视为一个约束最大覆盖问题,通过多阶段流程和人工干预修复阶段来确保时间配对和质量控制。该方法成功地从初始预算中填充了所有层级,并通过其修复循环恢复了相当一部分配对,从而发布了STRATA-S12语料库,该语料库已被证实适用于自监督预训练。 AI

影响 增强了地球观测的数据采集策略,可能改进该领域的自监督学习模型。

    面向STRATA-S12构建的赤字驱动分层采集:一个用于自监督学习的开放SAR-光学语料库

    Building a co-registered SAR-optical corpus for self-supervised Earth Observation is above all an acquisition problem, yet the main multi-modal datasets are collected opportunistically, with no per-stratum quota control and no mechanism against the geographic dropout that non-uni…
