    千亿参数大模型时代,QQ浏览器团队十亿级小模型「摩天」登顶CLUE,极致压榨网络性能

    机器之心专栏 作者:Joshua 今年以来,中文 NLP 圈陆续出现了百亿、千亿甚至万亿参数的预训练语言模型,炼大模型再次延续了「暴力美学」。但 QQ 浏览器搜索团队选择构建十亿级别参数量的「小」模型,提出的预训练模型「摩天」登顶了 CLUE 总排行榜以及下游四个分榜。 2021 年,自然语言处理(NLP)领域技术关注者一定听说过预训练的大名。随着以 BERT 为代表的一系列优秀预训练模型的推出,先基于预训练,再到下游任务的微调训练范式也已经成为一种主流,甚者对于产业界来说,某种意义上打破了之前语义理解的技

    Google Earth Engine ——全球资源管理系统火灾信息(FIRMS)1公里数据集

    The Earth Engine version of the Fire Information for Resource Management System (FIRMS) dataset contains the LANCE fire detection product in rasterized form. The near real-time (NRT) active fire locations are processed by LANCE using the standard MODIS MOD14/MYD14 Fire and Thermal Anomalies product. Each active fire location represents the centroid of a 1km pixel that is flagged by the algorithm as containing one or more fires within the pixel. The data are rasterized as follows: for each FIRMS active fire point, a 1km bounding box (BB) is defined; pixels in the MODIS sinusoidal projection that intersect the FIRMS BB are identified; if multiple FIRMS BBs intersect the same pixel, the one with higher confidence is retained; in case of a tie, the brighter one is retained.
