Line 62:
# Layer <math>n </math> has hidden vector <math>h_{n, t}</math>, parameters <math>\theta_n</math>, and maps <math>f_{\theta_n} : (x_{n-1, t}, h_{n, t}) \mapsto (x_{n, t}, h_{n, t+1}) </math>.
 
Each layer operates as a stand-alone RNN, and each layer's output sequence is used as the input sequence to the layer above. There is no conceptual limit to the depth of thestacked RNN.
