The Research of Feature Selection Model Based on the Game Theory

This paper depicts the uncertainty of feature information by using mutual information entropy based on the game theory. It also exposes the underlying nature of the decision-making process that is founded on conflict and cooperation through the construction of a payment function. Finally, the paper seeks to provide a balance solution for this strategy by the payoff matrix so that the optimum feature subset can be obtained. This feature subset can improve the performance of the decision-making system; hence, the feature dimension catastrophe caused by the high feature dimension can be subsequently addressed. Consequently, after the above-mentioned methods have been used to conduct feature selection as applied in vehicle selection, it may stated that vehicle feature dimensionality can be compressed. The recognition efficiency can also be improved greatly.
