Perhaps Gary Marcus said it best himself when critiquing Numenta, yet another brain inspired company [0]:<p>[Brain inspired] models are arguably closer to how the brain operates than artificial neural networks. &quot;But they, too, are oversimplified,&quot; he says. &quot;And so far I have not seen a knock-down argument that they yield better performance in any major challenge area.&quot;<p>There are a few of these brain inspired machine learning companies, yet I cant think of a single one acquired by Google.<p>Probabilistic modeling is great when you dont have much data and want to inject prior knowledge in a cohesive way. However Google&#x27;s approach appears to be to create large and robust training sets to feed into somewhat conventional supervised learning frameworks.<p>[0] <a href="http:&#x2F;&#x2F;www.technologyreview.com&#x2F;news&#x2F;536326&#x2F;ibm-tests-mobile-computing-pioneers-controversial-brain-algorithms&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.technologyreview.com&#x2F;news&#x2F;536326&#x2F;ibm-tests-mobile...</a>
