IBM、NASA與Hugging Face開源地理空間基礎模型

基於美國NASA衛星資料以及IBM基礎模型技術而成的IBM NASA Geospatial模型,透過機器學習模型分享平臺Hugging Face對外開放存取

IBM本周宣布,已於Hugging Face上開源基於美國國家航空及太空總署(NASA)衛星資料的watsonx.ai地理空間基礎模型,為全球首個與NASA合作的AI基礎模型。

IBM與NASA是在今年2月宣布結盟,當時IBM即打算要利用NASA的地球觀測衛星資料來打造各種基礎模型,以供全球的研究人員更容易應用NASA的資料,其中一項專案是利用Harmonized Landsat Sentinel-2(HLS)的衛星資料(下圖)來訓練IBM的地理空間情報基礎模型,整合來自美國地質調查局(USGS)的Landsat,以及由歐洲太空總署(European Space Agency,ESA)主導的Sentinel-2衛星資料,來提供一致且連貫的衛星影像。

此一名為IBM NASA Geospatial的開源模型使用了包含HLS專案在內的大量衛星及遙測數據,使用者可透過機器學習模型分享平臺Hugging Face存取。

IBM解釋,IBM NASA Geospatial是由IBM與NASA共同於HLS上展開為期一年的訓練,已根據洪水及大火的標記資料進行微調,僅使用一半的標記資料便改善了15%的效能,再藉由其它的微調將可重新部署基礎模型來執行追蹤森林砍伐、預測農作物產業,或是監控溫室氣體等任務。

此外,該模型也借助了IBM的基礎模型技術,IBM甫於今年7月發表商業性的AI平臺 watsonx,也計畫於今年透過IBM Environmental Intelligence Suite推出商業化的地理空間模型。
