Long Short-Term Memory dramatically improves Google Voice etc – now available to a billion users

A type of “Recurrent neural networks” architecture initially developed in Juergen Schmidhuber’s research groups at the Swiss AI Lab IDSIA and TU Munich greatly improved Google Voice (by 49%) and are now available to a billion users. You can find the recent Google Research Blog on this, by Haşim Sak, Andrew Senior, Kanishka Rao, Françoise Beaufays and Johan Schalkwyk:


This is a speech recognition application of “Long Short-Term Memory (LSTM)” Recurrent Neural Networks (since 1997) [1] with “forget gates” (since 1999) [2] and “Connectionist Temporal Classification (CTC)” (since 2006) [3].

Google is using the LSTMs also for numerous other applications such as state-of-the-art machine translation [4], image caption generation [5], natural language processing, etc.

  • so excited that you’ve made this happen! looking forward to reading and seeing all your prt.aessgohrnk you so much for the lovely buntings! so sweet and special delivery too!!!Holly

  • Alright alright alright that’s exactly what I needed!

  • Lesutopies > Pendant le téléchargement (sur Emule ou ailleurs) tu rends ton fichier disponible au partage des autres utilisateurs. Même si la copie privée est autorisée, tu deviens donc un méchant pirate (même si tout le monde ne fait que de la copie privée ?)

  • You can certainly see your enthusiasm in the work you write. The world hopes for even more passionate writers like you who are not afraid to say how they believe. Always go after your heart.

  • was actually very logical.However, what about this? suppose you wrote a catchier title?I ain’t suggesting your information is not good, but suppose you added a title that grabbed people’s attention?I mean The WORST predictions you
