<p>but instead for something where real-valued outputs are expected?</p>

<p>Maybe we could change it from </p>
<p>arma::Row</p>
<p>to?</p>
<p>arma::Row</p>
<p>I am mention about the codes of ffn, ann and rnn,things like </p>
<p><code>void Predict(arma::mat& predictors, arma::mat& responses);</code></p>
<p>Could we add an overloaded function, like</p>
<p><code>void Predict(arma::mat& predictors, arma::Row<double>& responses);</code></p>
<p>To the class?</p>
