<p>I have a question about the serialization, FFN accept the reference of the outputLayer, but this make it very hard to serialize, could I make it take the copy or rvalue of the outputLayer?</p>
<pre><code>template<typename Network, typename OutputLayer>
FFN(Network &&network, OutputLayer &&outputLayer,
PerformanceFunction performanceFunction = PerformanceFunction()) :
network(std::forward<Network>(network)),
outputLayer(std::forward<outputLayer>(outputLayer)),
performanceFunction(std::move(performanceFunction))
//
</code></pre>
<p>If the users need to access the output layer, we could add a public api for them to access it Any suggestions?</p>
