Modern AI walking on the Bionic road

in the last century60-70, Canadian neuro-physiology specialistDavid Hubel (1926-2013)with the Swedish physiology familyTorsten Wiesel(1924-) Close cooperation, based on experiments, to find out the response mechanism of the brain vision system to external stimulation signals, proved the multi-level structure of the cerebral cortex, and established the Bionics Foundation of modern Artificial intelligence, and won1981The annual Nobel Prize in Medicine.

2006The Canadian artificial intelligence expert-Geoffrey Hintonpublished a signature article in the journal Science, which states: Deep neural Networks (DNN) The difficulty in system training can be achieved by "layer-by-level initialization" (layer-wisepre-training) to effectively overcome, from then on. The deep neural network is turned on (DNN, also known as "deep Learning") of the research and application of the world tide.

in fact, deep learning (deeplearning) is the core technology of modern AI. Google, Microsoft and Baidu are the "Big three" in the field of modern AI. They have a huge amount of data andDNNtechnologies, such as: -years Oneat a meeting in Tianjin, Microsoft (China) presented a fully automated "simultaneous interpretation" system, with speakers speaking in English, computer one go in the background, speech recognition, English-Chinese machine translation, and Mandarin speech synthesis, with very smooth results. Microsoft is using deep neural network technology.

the Microsoft has launched the Microsoft "Cortana" ( Cortana ) Voice assistant and Microsoft "Xiaoice" network robot, go all DNN Bionics Road.

We ask: where is the background computer for Microsoft Cortana and Xiaoice? Is it a large server? Not also. In general, the Deep neural network system consists of tens of thousands of computers (CPU or GPU processor), which is centrally installed in a computer building, called the "Artificial Brain" (building), full of panache! In the near future, when you talk with foreigners, the use of their own smartphones, with the help of artificial brains, without translators, Chinese and English direct dialogue, free communication, no longer a dream!
