艾力克斯·格雷夫斯 (计算机科学家)
艾力克斯·格雷夫斯(英语:Alex Graves)是一名计算机科学家。在DeepMind担任研究科学家之前,他在爱丁堡大学获得理论物理学学士学位,并在IDSIA的于尔根·施密德胡伯指导下获得了人工智慧博士学位[1]。他还曾在慕尼黑工业大学的施密德胡伯和多伦多大学的杰弗里·辛顿手下做过博士后[2]。

在IDSIA,格雷夫斯通过一种称为连接主义时间分类(CTC)的新方法训练长短期记忆神经网路[3]。这种方法在某些应用中的表现优于传统的语音识别模型[4]。2009年,他的CTC训练的LSTM是第一个赢得模式识别比赛的循环神经网路,并赢得连接手写识别方面的几个比赛[5][6]。这种方法已经变得非常流行。Google在智慧型手机上使用CTC训练的LSTM进行语音识别[7][8]。
