WebJan 1, 2024 · The LSTM deep learning model is used in this work as mentioned for different learning rates using the Adam optimizer. The functioning is gauged for accuracy, F1-score, Precision, and Recall. The present work is run with LSTM deep learning model using Adam as an optimizer where the model is constructed as shown in Fig. 2.

We see here the same “sweet spot” band as in the first experiment. Each learning rate’s time to train grows linearly with model size. Learning rate performance did not depend on model size. The same rates that performed best for … raymond bonaria

Then the corresponding step calculates 0.9*current moment + 0.1*current gradient. You can think of this as a weighted average over the last 10 gradient descent steps, which cancels out a lot of noise. However initially, moment is set to 0 hence the … raymond bollinger
