<p>In <a href="https://github.com/mlpack/mlpack/commit/3ad083bcbf243915de035eead1b0772ac3f35dee" class="commit-link"><tt>3ad083b</tt></a> I've fixed the <code>-Wunused-parameter</code> warnings.  They don't appear under gcc, but I think this may be because gcc might not issue warnings for functions it isn't actually compiling into something.  Just a guess though.  I fixed some <code>-Wunused-private-field</code> warnings in <a href="https://github.com/mlpack/mlpack/commit/fba66e1b4960b403dc258e3a3e1e7d75cd7275ab" class="commit-link"><tt>fba66e1</tt></a> and <a href="https://github.com/mlpack/mlpack/commit/660fd96eecf88245555a8651e1cbeff50cd66686" class="commit-link"><tt>660fd96</tt></a>.  With those fixes, do you still see warnings?  (Maybe at the level of Armadillo?)</p>

<p>Personally I like fixing warnings, in case downstream projects are compiling with aggressive warning settings (I think RcppMLPACK compiles with <code>-pedantic</code>?  I'm not certain though).</p>
