n=nna公式的意義？

n=nna是一種神經(jīng)網(wǎng)絡(luò )的激活函數（activation function）式子，其中n是輸入數據，nna是算法的名稱(chēng)（Narx Neural Network Acceleration）。

這種激活函數通常用于遞歸神經(jīng)網(wǎng)絡(luò )（recurrent neural networks），與其它激活函數相比，可以更好地處理序列數據和時(shí)序數據。n=nna式子的含義是將當前時(shí)間步的輸入數據和前面時(shí)間步的輸出結果一起輸入神經(jīng)網(wǎng)絡(luò )，實(shí)現前向反饋和反向傳播的計算。
