For a book published in late 2014, it&#x27;s very strange that this book doesn&#x27;t seem to mention any of the state of the art components in neural networks, including:<p><pre><code>   - Convolutional neural networks 
   - LSTMs
   - GRUs 
   - Autoencoders 
   - Attentional mechanisms 
   - Variations on SGD (Adagrad, Adadelta, RMSProp, ADAM)</code></pre>
