&gt;I was particularly surprised that the method exactly recovers the Big-5 components of personality from the results of the survey questions.<p>Why?  Is that a standard dataset?  They could have just cherrypicked tasks.<p>I also noticed that they seem to only have the actual computation working for discrete random variables (integer features) right now, which limits its applicability.  They also seem to use mass-function estimators, which again can work well for discrete data while becoming statistically intractable when dealing with continuous random variables.<p>&gt;The whole idea of &quot;simplest model that explains most of the data&quot; has always been very appealing to me.<p>In this case it&#x27;s a bit more like, &quot;The set of latent variables that best screen off the observables from each-other.&quot;
