<p>There is something really weird. The GMM version trains almost instantly while the HMM takes days...</p>
<p>Here is the HMM version: </p>
<div class="highlight highlight-source-c++"><pre> <span class="pl-k">auto</span> hmm = std::make_unique<HMM<GMM>>(<span class="pl-c1">1</span>, GMM(<span class="pl-c1">64</span>, <span class="pl-c1">9</span>))
std::vector<arma::mat> images;
<span class="pl-c">//Fill images</span>
hmm-><span class="pl-en">Train</span>(images);</pre></div>
<p>Here is the GMM version: </p>
<div class="highlight highlight-source-c++"><pre> <span class="pl-k">auto</span> gmm = std::make_unique<GMM>(<span class="pl-c1">64</span>, <span class="pl-c1">9</span>);
std::vector<arma::mat> images;
<span class="pl-c">//Fill images</span>
gmm-><span class="pl-en">Train</span>(images[<span class="pl-c1">0</span>]);
<span class="pl-k">for</span>(std::<span class="pl-c1">size_t</span> i = <span class="pl-c1">1</span>; i < images.size(); ++i){
gmm-><span class="pl-c1">Train</span>(images[i], <span class="pl-c1">1</span>, <span class="pl-c1">true</span>);
}</pre></div>
<p>Either there is something wrong with this code and I don't use GMM/HMM correctly or there is something definitely wrong in the library. </p>
