编辑|张倩 导 读:近日,位于中关村的深度机智全球首次使用全新范式——人类学习, 在多个国际 Benchmark 上取得 SOTA ,史无前例地使用全新架构( 仅使用 人类 第一 视角数据、零真机数据 )击败 Physical Intelligence 和英伟达等头部巨头 二十多个百分点 , 并在两会开幕首日被央视报道 。而这一全新架构的诞生,得益于团队 在人类学习路线上一年多的全力积累。无独有偶,近期英伟达也发布了人类学习的初步尝试。 当国内具身智能领域还在争论真机数据和仿真数据哪个更有效时,硅谷却在悄悄达成另一项共识。 农历新年刚过,英伟达就发布了一项重磅成果 ——EgoScale。这是一个将人类灵巧操作直接「传授」给机器人的全新框架。 研究人员给大模型喂了超过 2 万小时的人类第一视角视频。结果证明:只要不断增加人类的示范数据,机器人的操作能力就能稳步提升。论文的第一作者更是直 接点破了这层窗户纸:「 提升机器人灵巧性的关键,在于堆更多的人类数据,而不是机器人真机数据。 」 这不禁让人想起英伟达年前的另一项王炸 ——DreamDojo。那个 用 4.4 万小时人类第一视角视频训练出来的模型 ,展现出了极 ...
