科技日报北京11月7日电 (记者张佳欣)人工智能(AI)"读心术"可通过读取大脑活动,"看懂"人脑中 的画面——这听起来像科幻小说,如今却离现实更近一步。日本NTT通信科学实验室研究团队开发出一 种名为"心智字幕"的新技术,能利用AI模型,根据受试者大脑活动生成其所见或脑中想象画面的文字描 述,准确度非常高。研究成果发表于新一期《科学进展》杂志。 这一技术不仅揭示了人脑如何在语言形成前表征外部世界,还有望帮助因中风等原因导致语言障碍的患 者,通过脑机接口更顺畅地表达想法。 要解码大脑对复杂内容的理解,例如短视频或抽象形状,一直具有挑战性。此前研究大多只能提取出关 键词,难以还原完整语境,例如视频的主角是谁、发生了什么动作。 英国《自然》杂志评论称,这项基于非侵入式功能性磁共振成像的技术,未来有望推动脑机接口的发 展,使植入设备能更直接地将人的思维转化为文字或语音,从而帮助语言受损者恢复交流能力。 【总编辑圈点】 当脑机接口遇上人工智能,"心有灵犀"正从浪漫想象步入现实。其原理是,当我们看视频或画面时,大 脑会发出各种各样的神经信号,脑机接口技术负责捕捉这些信号,而人工智能模型则负责解码和重构这 些信号,一场科 ...
