O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
GRU in TensorFlow
To change the LSTM example in the last section to the GRU network, change the cell type as follows and the TensorFlow takes care of the rest for you:
cell = tf.nn.rnn_cell.GRUCell(state_size)
The complete code for the GRU model is provided in the notebook ch-07a_RNN_TimeSeries_TensorFlow.
For the small airpass dataset, the GRU has shown better performance for the same number of epochs. In practice, GRU and LSTM have shown comparable performance. In terms of execution speed, the GRU model trains and predicts faster as compared to the LSTM.
The complete code for the GRU model is provided in the Jupyter notebook. The results from the GRU model are as follows:
train mse = 0.0019633215852081776 test mse = 0.014307591132819653 ...
