When return_sequences=True, an output is generated for each timestep. So if there are 5 LSTM Cells in your layer, there will be 5 outputs, one per cell. When return_sequences=False, only the last output of the forward pass (located at timestep T-1) AND the last output...
your output is 2D so set return_sequences=False in the last LSTM cell your last layers are very messy: no need to put a dropout between a layer output and an activation you need categorical_crossentropy and not sparse_categorical_crossentropy because your target is one-hot encoded LSTM expe...
