Guide language: The United States " even the line " magazine network edition is written today civil say, although nerve network technology is early,going up 80 time had become the century popular domain, but become silent gradually however later. However, as the development of the emerge in large numbers of new pattern and GPU, the attention of the tycoon of science and technology such as song of together with cereal, Microsoft and IBM, this one domain once more hot.

Nerve network
When Gu Ge develops operating system of shift of newest generation Android, this network tycoon unscrambled the means that speech dictates to make a few heavy major key rectify to this system. It installed with " nerve network " the speech recognition system that is a foundation, namely the computer study system of head of an imitate person.
Look in a lot of users, result clearly, fanhao of Vinson spy · overcomes the Gu Ge's researcher that includes to participate in this project among them (Vincent Vanhoucke) . "Just undertook adjustment can achieving so good result to the model, surprising really. " he says.
Fan Haoke expresses, system of new edition Android (jelly beans) speech mistake is led than going up generation system dropped about 25% , the user satisfaction that promoted speech the instruction is spent. He expresses, the user is willing to use more natural language when giving out speech to dictate more. In other words, their be the most popular t mobile prepaid cards havior already not so resembling is to be in spoke with the robot. "This changed the behavior way of people really. " the most popular memory card digital cameras he says.
Nerve network algorithm changed operation pattern of science and technology and us to use the pattern of science and technology greatly, and speech instruction is an among them example only. Although took the place of early to had made one of the most popular research fields 1980, nerve network becomes silent gradually however in recent years. Nevertheless, contend for photograph exploration as Gu Ge, Microsoft and IBM the economic value of this one technology, this domain once more hot.
modern dining chairsSpeech analysis
When you and software of Android speech recognition speak, your sound spectrum can be broken up, deliver 8 computer in sending Gu Ge giant server network next, fanhao overcomes recycle and the logarithm of nerve network model of his group development is free memory card digital cameras handled according to undertaking. Gu Ge is very apropos be good at breaking up huge computational job to process data quickly. And to study specific method, gu Ge gave Jeff · task allocation enlighten favour (Jeff Dean) and his engineer group, the contribution with this the famousest group is heavy model the working mode of contemporary data center.
Nerve network overcame such researcher to offer a kind of way for Fanhao, help its study varied pattern -- in jelly beans, the sound spectrum that is user speech pursues -- forecast next may appear why to be planted brand-new configuration. This kind of analogy results from biology, the nerve inside airframe yuan formed a network with other cell, make can process signal with special kind. In the nerve network that uses in jelly beans, gu Ge may analyse the voluminous data in real world, the working way that makes a variety of models describe a language thereby -- for example, among them a kind of speech that can handle English to give out searchs a request.
"Believe before p free scooby costume eople early -- the part results from the content that you see in cerebrum -- should acquire excellent perceptive system, use many functions layer with respect to need. " Xin Du of · of benefit of Qiao Fu of professor of science of Toronto university computer (Geoffrey Hinton) says, "But the problem depends on, how to learn these content efficiently. How to learn these content efficiently..
The image that Android films next speech dictate above all, model of its nerve network is used to analyse the content that user place says by Gu Ge later.
Gu Ge's software can try to understand every independent part in speech above all -- the different vowel that comprises a word namely and consonant. This is a layer of nerve network. Subsequently these information spread out reuse to guess complexly, every are thorough one, the result that its guess can be close to the true semantics of the user more.
Nerve network algorithm still can be used at analysing a picture. "You hope to search segment of a few constructions in resembling element, for example, a brim in the picture. You own detector of a feature probably layer, can explore little margin such thing. Should explore after finishing, still can have another feature detector layer, can explore the combination free canon ef 15mm of the brim, for example horn of a few edges. Once finish, still can come to again, go down continuously repeatedly so. " Xin Du says.
The technology progresses
It is so-called and OK that nerve network took the place of early 1980 the function with similar implementation, but it is very difficult however to should accomplish the pattern of this kind of analysis that Xin Du describes.
But appeared however 2006 two big significant change. Above all, xin Du and his group found a kind of better way to plan deep-seated nerve network -- this kind of network can have many different connection layer. Next, city of low GPU face makes academic orgnaization had more cheap and quick way to handle computation billions of times. "This brought tremendous change, because our computational speed promoted 30 times between one night. " Xin Du says.
Nowadays, nerve network algorithm is permeating speech recognition and graphical software stage by stage most popular selling t mobile prepaid cards in, dan Xin thinks suddenly, this kind of technology can be used at any need to have the field that forecast. Last year in November, a group of Toronto university uses element of medicaments of nerve network dope possible in real world effect way.
Enlighten favour express, gu Ge is now in many paragraph product use nerve network is algorithmic -- some just try, some are not -- but progress not as good as the speech recognition software of jelly beans. "Picture search domain also has apparently use value. " he says, "What you hope use picture is medium for certain is certain deciding this like always is what object after all. " cereal song vista also can use nerve network algorithm distinguish have between the different object that its film why difference -- for example, a house and a license plate.
Somebody feels this technology and Everyman have nothing to do probably, but note the following case please: Include enlighten favour inside Gu Ge researcher developed network of a nerve last year, can identify the cat in YouTube video through self-study.
Microsoft and IBM also are studying nerve network. Last year in October, microsoft overcomes · to play assorted moral character in presiding research house (the speech that Rick Rashid) revealed to be based on nerve network in Tianjin handles software. In revealing a process, lashende makes a speech with English, each metropolis halt. Those who make an audience surprizing is, the software of Microsoft meets the synchronism word interpreter him become Chinese, next " say " come out. This software is OK even self-correcting tone, imitate Lashende's sound.
"This domain has a lot of jobs to want to do, but this technology has perspective very much, our hope can break the language dividing line between person and person inside a few years. " he says, "My individual thinks, this will make the world better. " (think of far)
