[人人能懂AI前沿] 回忆的瓶颈,思考的深度与语言的曲率

from AI可可AI生活

你有没有想过,AI的大脑里到底是什么样子的?当它答不上来问题时,究竟是知识库里没有,还是只是暂时“丢了钥匙”?当它写出一长串思考过程时,我们又该如何分辨它是在“深度思考”,还是在“无效瞎忙”?本期节目,我们将通过五篇最新的论文,一起窥探AI的心智世界:从给语言做一次“CT扫描”,看懂语义的弯曲,到发现AI竟能凭语言统计“画”出世界地图,再到用“金发姑娘”策略为它匹配“刚刚好”的练习题。准备好,让我们一起出发,探索AI思考的奇妙运作机制!00:00:40 大模型知道答案,为什么就是不说?00:05:48 你的努力,是“真忙”还是“瞎忙”?00:11:04 给语言做个CT扫描,文本里的弯曲与折叠00:18:28 大模型“脑”中的世界地图,原来是这样画出来的00:24:03 AI刷题的“天花板”在哪?本期介绍的几篇论文:[CL] Empty Shelves or Lost Keys?
