Do you recommend any good primers on topology? I thought this (<a href="https:&#x2F;&#x2F;colah.github.io&#x2F;posts&#x2F;2014-03-NN-Manifolds-Topology&#x2F;" rel="nofollow">https:&#x2F;&#x2F;colah.github.io&#x2F;posts&#x2F;2014-03-NN-Manifolds-Topology&#x2F;</a>) was an interesting article and I see what looks like some great papers and videos available at <a href="http:&#x2F;&#x2F;www.ayasdi.com&#x2F;approach&#x2F;data-scientist&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.ayasdi.com&#x2F;approach&#x2F;data-scientist&#x2F;</a>, but I don&#x27;t know the difference between homotopy and homology (yet) :) .<p>What kinds of infrastructure&#x2F;tech do you think will have the most utility for topological data analysis in the near future? E.g., GPUs, Apache Spark, FPGAs, etc.<p>Any thoughts on an Ayasdi public offering? I&#x27;d like to consider investing but I don&#x27;t have millions of dollars (yet) :) .<p>Thanks for your time.
