陨石登陆地球数据
该数据集《Meteorite Landings on Earth Data》主要用于多分类任务，数据形态以文本为主，应用场景偏向天文科学。 题目说明：Detailed records of 34,500+ meteorite landings worldwide. 任务类型：文本多分类。 建议流程：先做文本清洗与分词，再比较 TF - IDF+线性模型 与 预训练语言模型。 评估建议：使用分层切分或交叉验证，优先关注 F1、Recall、AUC 等分类指标。 可用文件：Meteorite_Landings.csv。 This dataset provides a comprehensive collection of meteorite landings worldwide, compiled by The Meteoritical Society and made available through NASA’s Open Data Portal. It includes 34,513 recorded meteorites with key details such as location, type, mass, fall status (whether the meteorite was observed falling or found later), and geographical coordinates. The data has been updated to reflect new meteorite discoveries and includes fields like: Name & Type: Meteorite classification Mass (grams): Weight of the meteorite Fell or Found: Whether it was seen falling or later discovered Year: The year of discovery or fall Location Data: Latitude, longitude, and geo - coordinates Source: Original Data Provider: The Meteoritical Society
