Abstract

U ovom završnom radu opisana je struktura i način funkcioniranja umjetnih neuronskih mreža, te njihova povezanost s biološkim neuronskim mrežama. Zatim je opisan dinamički neuron i struktura dinamičke neuronske mreže. Neuronska mreža u strukturi skrivenog sloja ima dinamičke neurone drugog, četvrtog ili šestog reda, a učena je metodom povratnog rasprostiranja pogreške (eng. error back-propagation). Radi ubrzanja učenja u mrežu je dodan momentum prvog reda. Kasnije se funkcionalnost mreže testira na proporcionalnom članu prvog reda i mreža se testira u svrhu filtriranja odaziva estimatora trošenja reznih alata.

Abstract (english)

This paper describes the structure and the operating principle of artificial neural networks, as well as their link to biological neural networks. The structures of a basic dynamic neuron and a dynamic network are defined. The network's hidden layer contains either second, fourth or sixth order dynamic neurons. The network is trained via the error backpropagation method and the training speed is increased with the use of a first order momentum. The network’s functionality is tested using a first order proportional controller and later for the purpose of filtering the response of a cutting tool wear estimator.
