 Conclusion and References I-non-diffusive neural network solver ye-one-dimensional scalar HCLs Ukuhlaziywa & References 5. Ukungena ngemvume Kule isihloko, sinikeza indlela original yokuxhumana nezinsizakalo ze-hyperbolic using a non-diffusive neural network method. The DLs futhi ukuguqulwa izinsizakalo zokuhlobisa ezisetshenziselwa i-DLs, futhi lapho isixazululo ifanelekayo. Siye zisebenzisa networks ne-neural ukuguqulwa kwe-DLs kanye nesisezinsizakalo zokuhlobisa kwelinye subdomains. I-networks ibhekwa ngokunciphisa isizukulwane esebenzayo esilinganiselwe (norm of the) izinsizakalo zokuhlobisa izinsizakalo, izimo zokuhlobisa kanye nezimo zokuqala kanye nezimo ze-Rankine-Hugoniot. Lolu hlobo lwezinhlobonhlobo lwezocingo ngaphandle kokusetshenziswa isisombululo esincane se-HCL. Izinsizakalo ezinye zingasetshenziselwa ukulungiselela isixazululo kanye ne-DL Uma ingcindezi global yama-loss functional iyatholakala ngokushesha, i-convergent ngokushesha futhi enhle (Schwarz) method of decomposition ye-domain ingasetshenziselwa. Lezi zilandelayo ivumela ukuxuba inqubo ye-optimization ngokusebenzisa ukuphuculwa kwezinkampani zezinkampani zezinkampani zezinkampani zezinkampani ezivela ku-global approximate isixazululwa, njenge-showed ku [23]. Ngezinye umsebenzi esizayo, sinikezela isicelo le-methodology ku-high-dimensional problems. CRediT authorship contribution statement Umbhali wahlanganyela ngokulinganayo. Declaration of competing interest I-Authors ibhalisele ukuthi akuyona izinzuzo ezithakazelisayo ze-financial noma izinhlobonhlobo zebhizinisi ezinokuthi ziye ziye ziye ziye ziye ziye ziye ziye ziye zihlanganisa umsebenzi esifundeni. Data availability Akukho idatha asetshenziselwa isifundo esifundisiwe kulesi sihloko. Ukuhlobisa [1] J.-M. Ghidaglia no-F. Pascal.
