There are not so many nonparametric Bayesian alternatives yet for multiview clustering. So, this software is a really nice contribution!<p>Alternatives:<p>* The group of Ghahramani [1] use a stick-breaking representation instead of the authors of CrossCat, plus a variational method rather than sampling.<p>* It&#x27;s even possible to reuse features across categories by stacking an Indian Buffet Process and a Chinese Restaurant Process [2].<p>The difficulty for the person who has to cluster the data is that the inference method has to be obtained from scratch. Each time that something small changes, not only the model has to be altered, but also a new inference process has to be implemented.<p>So, suppose we have dependencies between the categories, they might be spatial, they might be temporal, this leads again to more complex processes.<p>I think it&#x27;s important for CrossCat to describe what kind of structure it can discover. To be future-proof it&#x27;s also important to describe what the roadmap will be.<p>[1] <a href="http:&#x2F;&#x2F;www.ece.neu.edu&#x2F;fac-ece&#x2F;jdy&#x2F;papers&#x2F;nonparametric-multiclust-kdd10.pdf" rel="nofollow">http:&#x2F;&#x2F;www.ece.neu.edu&#x2F;fac-ece&#x2F;jdy&#x2F;papers&#x2F;nonparametric-mult...</a><p>[2] <a href="http:&#x2F;&#x2F;machinelearning.wustl.edu&#x2F;mlpapers&#x2F;paper_files&#x2F;AISTATS2012_NiuDG12.pdf" rel="nofollow">http:&#x2F;&#x2F;machinelearning.wustl.edu&#x2F;mlpapers&#x2F;paper_files&#x2F;AISTAT...</a>
