新的人工智能系统将想法转化为文字,以帮助无法说话的人
Scientists have developed a noninvasive AI system focused on translating a person’s brain activity into a stream of text.
科学家已开发出一种无创人工智能系统,致力于将人的大脑活动转化为文本流。
noninvasive [ˌnɒnɪn'veɪsɪv] adj 非侵害的;无创的
focus on 专注于;聚焦于
translate sth into 将某物转化为
The system, called a semantic decoder, could benefit patients who have lost their ability to physically communicate after suffering from a stroke, paralysis or other diseases.
这个被称为语义解码器的系统最终可能会使那些因中风、瘫痪或其他疾病而失去肢体交流能力的患者受益。
semantic [sɪ'mæntɪk] adj 语义的
decoder [ˌdiː'kəʊdə(r)] n [C] 解码器
suffer from(尤指长期)罹患
stroke [strəʊk] n [C] 中风
paralysis [pə'ræləsɪs] n [U] 瘫痪;麻痹
Researchers at the University of Texas at Austin developed the system in part by using a transformer model, which is similar to those that support chatbot ChatGPT.
德克萨斯大学奥斯汀分校的研究人员在一定程度上使用了一个转换器模型来开发这个系统,这个模型类似于支持聊天机器人ChatGPT的那种模型。
transformer [træns'fɔːmə(r)] n [C] 变压器
be similar to 和……相似
The study’s participants trained the decoder by listening to several hours of podcasts within an fMRI scanner, which is a large piece of machinery that measures brain activity. The system requires no surgical implants.
这项研究的参与者通过在功能磁共振成像扫描仪上听几个小时的播客来训练解码器,这是一种测量大脑活动的大型机器,该系统不需要手术植入。
scanner ['skænə(r)] n [C] 扫描仪
surgical ['sɜːdʒɪkl] adj 外科的
implant ['ɪmplɑːnt] n [C](通过手术被移植进入人体的)植入物
Once the AI system is trained, it can generate a stream of text when the participant is listening to or imagines telling a new story. The resultant text is not an exact transcript, rather the researchers designed it with the intent of capturing general thoughts or ideas. The trained system produces text that closely or precisely matches the intended meaning of the participant’s original words around half of the time.
一旦人工智能系统经过训练,当参与者正在听或想象讲述一个新故事时,它可以生成一串文本。最终的文本并不是一个精确的文本,研究人员设计它的目的是捕捉大致的想法或观点。
经过训练的系统产生的文本在大约一半的时间里与参与者的原话的意思非常接近或精确匹配。
generate ['dʒenəreɪt] vt 产生
resultant [rɪ'zʌltənt] adj 因而发生的
transcript ['trænskrɪpt] n [C] 抄本;转录本
intent [ɪn'tent] n [U] 目的;意向
general ['
