Thus for a whole sentence, we get a vector of size 4 as output from the RNN layer as shown in the figure. You can verify this by printing the shape of the output from the layer. importtensorflowastffromtensorflow.keras.layersimportSimpleRNNx=tf.random.normal((1,3,2))layer=SimpleRNN(4...

Let’s define an LSTM network with 32 units and an output layer with a softmax activation function for making predictions. Because this is a multi-class classification problem, you can use the log loss function (called “categorical_crossentropy” in Keras) and optimize the network using the ...
As for implementing attention in Keras.. There are two possible methods: a) add a hidden Activation layer for the softmax or b) change the recurrent unit to have a softmax. On option a): this would apply attention to the output of the recurrent unit but not to the output/input passed...
