2 days ago · The normal LSTM is unidirectional where it cannot know the future words whereas in Bi-LSTM we can predict the future use of words as there is backward information passed on from the other RNN layer in reverse. There is only one change made in the code compared to the LSTM, here we use Bidirectional() function and call LSTM inside. The reason for this is that the output layer of our Keras LSTM network will be a standard softmax layer, which will assign a probability to each of the 10,000 possible words. The one word with the highest probability will be the predicted word – in other words, the Keras LSTM network will predict one word out of 10,000 possible categories. The CNN has the second highest accuracy and is the second fastest model. In other words, the Convolutional Neural Network (CNN) is overall the most performant model. In terms of accuracy, it’ll likely be possible with hyperparameter tuning to improve the accuracy and beat out the LSTM.

I have a found a model that uses time distributed cnn that combines lstm together. But it requires 5 dimensions, but my training code only gives 4 dimensions. I have tried to set the 5th dimension, the time, as static but it seems like it would require me to take it as an input and not be static in the model. Standard approaches for developing applications won't help in providing accuracy.
