Considering self - recursion " structure can work on its inversion effect , so the paper uses contractive mapping genetic algorithm to search its optimal struct 考慮到自遞歸神經(jīng)網(wǎng)絡(luò)的結(jié)構(gòu)影響到其反演效果,本文利用壓縮映射遺傳算法來(lái)搜索其最佳的結(jié)構(gòu)。
( 4 ) the paper has studied the structure and training algorithm of self - recursion neural network . it also studies the convergence and stability of self - recursion neural network " training algorithm by using lyapunov method . then the paper use inversion method to simulate the vibration field of ground vibration caused by track traffic by self - recursion neural network for the first time ( 4 )研究了自遞歸神經(jīng)網(wǎng)絡(luò)的結(jié)構(gòu)及訓(xùn)練算法,利用lyapunov方法研究了自遞歸神經(jīng)網(wǎng)絡(luò)訓(xùn)練算法的收斂性和穩(wěn)定性,并首次利用自遞歸神經(jīng)網(wǎng)絡(luò)來(lái)反演軌道交通引起地面振動(dòng)的振動(dòng)場(chǎng)。
