On Some Characteristics of the New Generation Computers Oleg N. Granichin Sergey S. Sysoev
The Computer Generations ? 5
Qualitative Generations Leaps Task oriented machines. Operating Systems, multitasking, Universal Computer, HLL
What Is Next? The Intelligent System
One Approach of Creating the Intelligent System The External Part The Internal Part
Intelligent Choice Task 1Task 2Task N … Device 1Device 2 Device N …
The Internal Part Conditions For each considered particular task the system has the particular device which is able to optimize the solving of this task by an appropriate choosing the system parameter from some final set. Information from external world must be delivered to all such devices simultaneously.
The Internal Part Implementation Example
Informational Resonance
Possible Resonance Situations One and only one device has resonance Several devices have resonance None of the devices has resonance (the system parameters have to be adjusted)
The System Parameters Set
Optimization Task The function F has its minimum (or maximum) when the system has resonance, x – the system parameters, w – the stochastic parameter, obtained from the real world.
The Kiefer-Wolfowitz Procedure
The SPSA Algorithm
The SPSA Grounds
Advantages of the SPSA Algorithm Only one measurement of loss function per iteration needed Convergence with probability 1 with all kinds of disturbance The best convergence speed characteristics Allows tracking
