It’s been one full week since the Vis conference. Since then, I’ve met with Bei Wang (at Utah) and Carlos Scheidegger (at Arizona) twice to discuss the work Dr. Rosen and I are doing on the 0-dimensional PH project for CREU. I’ve received some great feedback from these two, in addition to the many students and faculty I spoke to at the Vis conference during the poster session. Here are some of the things I’ve worked on since then: • “Attracted”, or merged, two nodes together when a bar from the barcode is selected. This only occurs if the user right-clicks the bar. We added this feature to declutter the graph for low persistence edges by merging the two nodes[…]

Sorry to condense three weeks worth of updates into one. After Hurricane Irma hit my city things have been very hectic with power outages, getting back on schedule with courses, and preparing for traveling to Phoenix, AZ for the Vis 2017 conference. These past few weeks Dr. Rosen and I have been working on the finishing details for the project to present at the conference. We implemented an edge-bundling technique using the algorithm described in this paper. The next visual aid I’m working on is creating “super nodes”, where I will group low persistence nodes together. Unfortunately we missed the call for papers from PacificVis, so our next deadline we are shooting for is in December for EuroVis. I’m very[…]

This week I was able to invert the data currently stored inside the persistence diagram by creating a new function that sorts everything such that the most important information is displayed in the longest bars (while less important features are now in the shorter bars). I’ve also drawn a second persistence diagram on the right side of the screen and changed the overall size of each barcode to fit both on the interface without taking up too much space. The PD on the right does not function correctly yet, but the goal is to store a second set of persistent homology features that the user can click on when interacting with the force-directed layout. Dr. Rosen and I hope that[…]

Last week I started my second-to-last semester at USF and so far I’ve met with Dr. Rosen four times to discuss the project we’re working on for CREU. Recently we found out our poster submission to Vis 2017 was accepted for presentation, and hopefully I’ll be attending the conference between October 1st-6th. Below is a video Dr. Rosen and I created for the fast forward/video preview of our project. The next deadline we are working towards is a paper submission to IEEE PacificVis 2018. The abstract is due 9/22 and our full paper will be due 9/29. The paper we are submitting is the work done in 0-dimensions as described in our CREU proposal (and detailed in the 25-second video[…]

I am a Senior Computer Science student in the College of Engineering at the University of South Florida. I have a completed Mathematics minor, with a focus in Probability Theory and Cryptography/Coding Theory. Currently I am a member of USF’s Research Experience for Undergraduates Program, where I study Visualization under Dr. Paul Rosen. A research proposal submitted by Dr. Rosen and I was recently accepted for funding by the Collaborative Research Experience for Undergraduates. I will be keeping a weekly blog to include tasks and results from our research project, titled “Using Persistent Homology to Drive Interactive Graph Drawing”.
