Topology Meets Big Data

SF Data Mining is looking forward to an exciting Peninsula event in downtown Palo Alto. We are fortunate to have a talk hosted by and at Ayasdi.


Ayasdi is very excited to host the first ever Palo Alto SF Data Mining Meetup at their headquarters.

During the Meetup, Jesse Paquette will teach you about how the ancient branch of mathematics called topology is being leveraged for big data analysis in the form of Topological Data Analysis (TDA). More specifically, you will learn why and how topology has been applied to big data in order to automatically surface hidden signals within high dimensional, high volume datasets.

Following Jesse, Muthu Alagappan, who was named to the 2013 Forbes 30 under 30 Sports list, will demo how he has leveraged Ayasdi Iris with TDA to reinvent and redefine the positions of basketball. His findings have led to him helping some of the top NBA teams in the nation, as well as landing him speaking opportunities at SXSW, TEDx, and MIT Sloan Sports Analytics Conference.


6:30 - 7:00: Beer and Pizza

7:00 - 7:30: Jesse Paquette explaining TDA followed by Q&A

7:30 - 8:00: Muthu Alagappan demoing his basketball analysis followed by Q&A

8:00 - 9:00: Networking

    Hey All!

    I hope you enjoyed the meetup. The videos are finally up

    Thanks Anthony for posting the links, was going to look for papers.

    For those of you who want more technical information on Topological Data Analysis I recommend the comptop preprint server:

    For a comprehensive overview of the different strains of TDA I recommend Gunnar's "Topology and Data" as a jumping off point:

    For more information on Iris there is a nature scientific report that covers similar ground as my talk but with a different perspective:

    The paper that originally published the method used by Iris is this one:

    That said, there are a number of strains of TDA that have developed since that paper was written. Some recent work on using sheaf theory can be found here:

    I was excited because I barely knew the rudiments of topology, and I was able to follow the presentation. It's heartening to see professional mathematicians do something other (better?) than cryptography and computational finance!

    In the future I think it would help people like me if the presenter cited the relevant theorems and papers so we can help ourselves fill in the holes of the high-level, hand-waving explanation.

    I definitely want more meetups on that topic. :)
    These were two great talks. Thanks for organizing this.

    Driving down from Oakland ... short notice, but anyone want a ride?

      I am travelling from Fremont, via 84. I can carpool with you if interested.

    Attendance at this event is quite limited, so please update your RSVP soon if you are unable to attend, so that others may plan to attend. Thanks!

    Any chance this'll be video taped?

    May 16, 2013

    • Miles M.

      I am planning on attending with some form of recording equipment for the event given the number of people on the waitlist.

      I have a decent portable digital audio recorder too. The more the merrier, right?

    looking forward it.

    But will we also discuss Postnikov towers?

    I've been wondering when network topology methods were going to pop up in this space...

    Unfortunately Palo Alto is a bit out of range, but it looks really interesting.
