the model has two towers)</p></li>
<li><p>Only one of the towers is needed to generate the signature</p></li>
<li><p>The last layer of the tower is a <strong>fully connected</strong> layer, the output of this layer is the <strong>signature</strong> generated from the model input</p></li>
<li><p>The number of units (aka neurons) in the last fully connected layer determines the since of the generated signature</p></li>
