Optimal Zone Strategy of Large Margin Search

3 Optimal Zone Strategy of Large Margin Search 

The purpose of industrial optimization is to improve the production process by optimal control, that is to achieve good product quality, high rate of recovery, low energy and raw materials consumption, low pollution and low production cost, etc. Since these targets are usually determined by many factors simultaneously, multivariate analysis has to be used to make mathematic modeling of an optimal zone in hyperspace spanned by operation parameters. 

One of the purposes of fault diagnosis is also to find an optimal zone in the high-dimensional space spanned by operation parameters in order to avoid the occurrence of fault. This is also usually a multivariate problem. 

If some sample points with large values of yt are the nearest neighbors to each other in a unified zone, this unified zone can be used as the zone for optimal control. 

Similarly, if the good sample points and bad sample points can be mapped into a feature space and SVR method can define a straight line to describe the target values of all sample points in the feature space, and if the good points located near the upper (or lower) end of the straight line are the nearest neighbors to each other in a unified zone of the input space, this zone can also be used as the zone for optimal control.
