<i>&gt;The point here is that dimensionality reduction does not need to be done by inferring higher level concepts like headlights.</i><p>I get that, and it is a very useful result.<p>But what I was wondering about is whether humans can ever &quot;switch off&quot; high level reasoning when they perceive sensory information. Even when the image is supposedly abstract, humans may be making stuff up, and that might influence perception and dimensionality reduction, similar to what&#x27;s happening in a Rorschach test.<p>And that&#x27;s why I don&#x27;t believe that what the paper shows is actually &quot;How the Brain Can Handle So Much Data&quot; -- the title of the linked article.
