This will be a short post because most of the work I’m doing for the next two weeks (including this last week) is writing a rough draft of our paper. I finished up some last bits of coding, the only thing left to do is add the bubble color sets which I still can’t figure out!! (I really hate eclipse projects).. but hopefully after my meeting with Dr. Rosen on Tuesday I’ll have it finished. This past week I made some minor changes to the graph layout: vertices are now 75% their original size and have a heavier mass, so they will take up less space on the screen. The edges are thinner and the barcode is also 60% its[…]

This is the final week of coding for our CREU project. Afterwards, I’ll begin my writing for our paper submission to EuroVis in December. Our schedule plan is something along the lines of: 10/31/17: Be done with code 11/1/17: Start writing 11/14/17: Finish writing/Get help from Rosen and Mustafa 12/6/17: Abstract due 12/13/17: Full paper due All that’s left for coding is the finishing touches of when the bubble color sets pop up to the screen when a barcode is being hovered over. This past week I worked on moving over the barcode (found on the left side of our graph) to a new class where each bar from the barcode is an object, with attributes like set size, color,[…]

This week I’ve been working on creating two new classes that should make our code cleaner and faster. It feels a bit like restarting — digging through fine details of code I’ve written over the course of 5 months and figuring out how to not break it along the way. I should hopefully have this done by next week, and I’ll be able to start writing the paper for EuroVis. We started an overleaf for the paper that I’m sharing with Dr. Rosen and Dr. Hajij, who are both kind enough to offer helping me edit my writing once I’ve done enough word vomiting. EuroVis has a specific format that I have to figure out how to do in LaTeX,[…]

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”.
