Neural Network Computer Status and Development Trend
Dynamics and function in experimental studies to further clarify the brain's thinking process is still the main task of neural science, the actual synaptic function can be reduced and so the complex is due to neurons caused by the microscopic mechanism, namely, Each neuron is not Interpretation of the value of simple processing units,ghd gl?tteisen, can be regarded as a micro-surface is the advanced features of the computer processing unit. This required a lot of experimental ideas, and further study the activity of neurons, neural networks and the construction of the brain's memory, language and other advanced features. In technology research,ugg milano, in order to make practical neural computer, you must have the advanced features of the neural chip. To meet the high level of integration of neural networks and high speed, optical nerve and optical neural computer chip research is essential for the present, should pay attention to the problem as follows: â to improve communication skills and means to shorten the communication time; â¡ the entire network and reduce Cable's share volume; ⧠in the VLSI chip, reducing the external bow ãlines; ⣠reduce funding costs; @ Cang films in raising high-density VLSI, ultra-parallelism, it is also necessary to strengthen the software design and development, make the program a high degree of parallelization. 2. And trend of development of neural computer is now two directions along the first trial use of biological nerve cells in the brain of man-made worthy of the name; the other direction is to work on the hardware and software, by emulating the human brain to a computer with § 6 of the human brain functions, the sixth generation of the computer is to be completed on this basis. â prototype neural computer using nerve cells in many Japanese companies are engaged in this work, such as Mitsubishi Electric is engaged in the research squid mollusks Sanyo Electric guns use slug (slug scorpionfish) in neurophysiological research, and with Matsushita Electric Industrial Kyoto Prefectural University of Taiwan,ugg boots cheap, as of rat brain cells were long-term culture, successfully observed many cases of neural networks but the cells are living things, and easy death, it is difficult to get in the way the application of a word, the neural cells and organic matter compared to the use of silicon devices, will create a better neural computer,uggs ireland, but this work is still in the basic research stage, but also for many years to realize. â¡ computer simulated neural circuit from the hardware to emulate the human brain has been conducting the research, the use of simulation technology to produce high-performance computer is the formation of a craze nerve. Analog circuits using fewer number of components required can put a lot of neurons and rustic touch on a chip, imprison this through many synapses with parallel processing to complete learning, so that the learning speed to use digital mode a few times . On the other hand, make improvements to existing transistor to reduce further the number of transistors used as a new type of transistor, the input and output is no longer one to one, which can receive multiple inputs and outputs corresponding to input the sum of 1 \signal, it works and people like the nerve cells. Using this transistor, it is likely much less than it is now with the number of transistors and wiring to achieve the number of neural networks. T short parallel neural computer, information processing and learning for its own organization's ability to expand the scope of application to the von Neumann computer and traditional artificial intelligence techniques extremely difficult area. Practice, with the von Neumann computer logic and artificial intelligence technology to serial processing, intuitive rejection of the parallel neural computer information processing, a combination of the application may be a way to have a bright future research, but the real neural and neural network computer should have the same structure and same number of neurons, to simulate the human perception and intelligence activities, it now appears that goal is still far away, but as Professor Gan Lijun said, \started, should now make clear as a starting point, carry out engineering development. \It should be under the present conditions (level of theory, technology and process), and gradually move forward, continuous efforts.
