艾力克斯·格雷夫斯 (計算機科學家)

艾力克斯·格雷夫斯英語:)是一名計算機科學家。在DeepMind擔任研究科學家之前,他在愛丁堡大學獲得理論物理學學士學位,並在IDSIA于爾根·施密德胡伯指導下獲得了人工智慧博士學位[1]。他還曾在慕尼黑工業大學的施密德胡伯和多倫多大學杰弗里·辛顿手下做過博士後[2]

在IDSIA,格雷夫斯通過一種稱為連接主義時間分類(CTC)的新方法訓練長短期記憶神經網路[3]。這種方法在某些應用中的表現優於傳統的語音識別模型[4]。2009年,他的CTC訓練的LSTM是第一個贏得模式識別比賽的循環神經網路,並贏得連接手寫識別方面的幾個比賽[5][6]。這種方法已經變得非常流行。Google在智慧型手機上使用CTC訓練的LSTM進行語音識別[7][8]

格雷夫斯也是神經圖靈機[9]和密切相關的可微分神經計算機的創造者[10][11]
