The data processing apparatus includes: a recording unit that records electronic data; and a computing unit that performs computing using the electronic data, in which the computing unit includes a feature amount selection unit used for computing, and the feature amount selection unit performs feature amount selection including: a first step (S101) of ranking feature amounts and rearranging the feature amounts from top; a second step (S103) of creating a plurality of data groups using only a part of the feature amounts according to the order; a third step (S104) of calculating a value that is an index for evaluating prediction performance of a regression or classification problem using each of the data groups using only a part of the feature amounts; a fourth step (S105) of deleting feature amounts based on the calculated prediction performance index; and a fifth step (S106) of updating the order of the feature amounts, which are feature amounts other than the deleted feature amount, using the prediction performance index, in which the second step to the fifth steps are iterated (S102) until an optimal value of the prediction performance index calculated in the third step is no longer updated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data processing apparatus, data processing method and semiconductor manufacturing apparatus","description":"A data processing apparatus in which a trade-off between over-learning prevention and calculation load prevention is eliminated when creating a model formula is provided.
