Towards hard measurement and the formula decision-making technique thereof of the multicomponent alloy material of small sample test figure

The invention discloses a kind of formula decision-making technique of the multicomponent alloy material towards Small Sample Database, it is characterized in that carrying out according to following step: one, by injecting noise to small sample, recycling Bootstrap resampling, effectively expands small sample; Two, by maximum entropy neural net method, the sample data after expanding is trained, realizes the hard measurement of potential rule between the thermodynamic property of alloy material and polynary formula; Three, according to the requirement of enterprise to material property, determine the fitness function of genetic algorithm, global optimization obtains the formula decision-making of multicomponent alloy material; Four, in fitness function, introduce the sane Optimality Criteria of gradient descent method, can obtain the insensitive formula decision-making of the subtle change of material prescription.The invention provides hard measurement and the formula decision-making technique thereof of the multicomponent alloy material towards Small Sample Database of set of system, for shortening the design cycle of multicomponent alloy new product, the performance improving multicomponent alloy provides feasible method.
