If you’re somewhat new to Machine Learning or Neural Networks it can take a bit of expertise to get good models. The most important quantity to keep track of is the difference between your training loss (printed during training) and the validation loss (printed once in a while when the RNN is run on the validation … See more The two most important parameters that control the model are lstm_size and num_layers. I would advise that you always use num_layers of either 2/3. The … See more The winning strategy to obtaining very good models (if you have the compute time) is to always err on making the network larger (as large as you’re willing to … See more WebTraining RNNs. To train an RNN, the trick is to unroll it through time (like we just did) and then simply use regular backpropagation (see Figure 4-5). This strategy is called backpropagation through time (BPTT). redding west efficienies for sent https://reiningalegal.com
