WebOct 13, 2024 · We trained and evaluated the networks with the following architectures: a 64-neuron LSTM, a 64-neuron continuous-time (CT)-RNN and a 19-neuron NCP. Moreover, we compared these recurrent agents... WebArchitecture of a traditional RNN Recurrent neural networks, also known as RNNs, are a class of neural networks that allow previous outputs to be used as inputs while having hidden states. They are typically as follows: For each timestep $t$, the activation $a^ {< t >}$ and the output $y^ {< t >}$ are expressed as follows:
