&lt;div&gt;Le &lt;strong&gt;self-organizing map (SOM)&lt;/strong&gt; sono un particolare tipo di &lt;a class=\&quot;mw-redirect\&quot; title=\&quot;Rete neurale artificiale\&quot; href=&quot;http://it.wikipedia.org/wiki/Rete_neurale_artificiale\&quot;&gt;rete neurale artificiale&lt;/a&gt;.&lt;/div&gt;
&lt;p&gt;&amp;Egrave; addestrata usando l\'&lt;a title=\&quot;Apprendimento non supervisionato\&quot; href=&quot;http://it.wikipedia.org/wiki/Apprendimento_non_supervisionato\&quot;&gt;apprendimento non supervisionato&lt;/a&gt; per produrre una rappresentazione dei campioni di training in uno spazio a bassa dimensione preservando le propriet&amp;agrave; &lt;a title=\&quot;Topologia\&quot; href=&quot;http://it.wikipedia.org/wiki/Topologia\&quot;&gt;topologiche&lt;/a&gt; dello spazio degli ingressi. Questa propriet&amp;agrave; rende le SOM particolarmente utili per la &lt;a class=\&quot;new\&quot; title=\&quot;Visualizzazione scientifica (pagina inesistente)\&quot; href=&quot;http://it.wikipedia.org/w/index.php?title=Visualizzazione_scientifica&amp;amp;action=edit&amp;amp;redlink=1\&quot;&gt;visualizzazione&lt;/a&gt; di dati di dimensione elevata. Il modello fu inizialmente descritto dal professore &lt;a title=\&quot;Finlandia\&quot; href=&quot;http://it.wikipedia.org/wiki/Finlandia\&quot;&gt;finlandese&lt;/a&gt; &lt;a title=\&quot;Teuvo Kohonen\&quot; href=&quot;http://it.wikipedia.org/wiki/Teuvo_Kohonen\&quot;&gt;Teuvo Kohonen&lt;/a&gt; e spesso ci si riferisce a questo modello come &lt;strong&gt;Mappe di Kohonen&lt;/strong&gt;. .-.-&lt;/p&gt;
