Reduction principle of the mathematical model / Yaroslav Matviychuk // Advanced information and communication technologies–2017 (AICT–2017) : рroceeding of 2nd International conference, 4–7 July, Lviv, Ukraine. – Lviv, 2017. – P. 142–145. – Bibliography: 4 titles.https://ena.lpnu.ua/handle/ntb/39310The detection and elimination principle of redundant elements in the mathematical model is proposed in this paper. The efficiency of the proposed approach has been analyzed based on the neural network model of economic system and differential equations model. Results prove the 16 times increasing in the model accuracy.142-145enmathematical modelreductionneural networkincorrectnessODEArticle©2017 IEEE
