  • The Meaning of Underscores in Python
  • Tried to add research code to timesheet. No luck. Let T know.
  • Tried to access new Jira and Confluence pages, They are visible thought the OpenVPN tunnel. but the login/password does not work
  • Reading the Ketos User guide and annotating. Finished – sending to Aaron
  • TEM meeting at 2:00

    • String matching, BOW, LSI competitors
    • Based on word2vec, combined with a TF-IDF scoring
      Trained on wikipedia
    • Trained on seperate training server?
    • Apps on the training server? Train one classifier for each field
  • Things we did in 2016
    • StanfordNLP+jsoup tool to categorize and tag web pages for statistical analysis

    • Google CSE interface, plus cleaning tools
    • Document centrality analysis tool (JavaFX! Woohoo!) (LSI, TF-IDF, PageRank, adjacency, etc calculations at interactive rates)(outputs for WEKA)
    • Use of above tool to create CSE search terms that improved craw precision by 500% (
    • Tagged hundreds of web pages because someone had to.
    • Proposal writing
    • Group polarization modeling using flocking agent-based simulation

  • Really tempted to call the HCIC poster ‘Precision and Recall Considered Harmful’. Maybe the CHIIR paper insted?
  • Got a good deal of work done over the weekend. Here’s my latest abstract: AbstractCover
  • Also made good progress on the poster. Will need to re-run the text for LMN -done: PosterPage
  • Sent both mockups off to Wayne
  • Anatomy of news consumption on Facebook
    • In this paper, we explore the anatomy of the information space on Facebook by characterizing on a global scale the news consumption patterns of 376 million users over a time span of 6 y (January 2010 to December 2015). We find that users tend to focus on a limited set of pages, producing a sharp community structure among news outlets. We also find that the preferences of users and news providers differ. By tracking how Facebook pages “like” each other and examining their geolocation, we find that news providers are more geographically confined than users. We devise a simple model of selective exposure that reproduces the observed connectivity patterns.

  • Send T my schedule – done
  • Clustering has been kicked under the bus. Need to respond, but also look for new work? Working on that with Aaron.
  •  I’m getting a ’99’ charge number for research.
  • Helping Aaron put his accounts back together
  • Meeting with Chris Y, T, Aaron and me
    • How do we segment off the Aaron/Phil work
    • Figure out BRC and tell them they’re wrong? How to make this about success?
  • Fixed a bug with CorpusManager where the code broke it the kept percent is 100%

12:30 – 4:00 BRC

  • Wrote up stories for upcoming 2-week(!) sprints
  • Long discussion with Bob and Aaron about SOMs

7:00 – 8:00 Research

  • Computer-mediated telepathy using NN to classify FMRI data tagged by human activity at the time (e.g. looking at an image)
    • Dr. Mary Lou Jepsen (wikipedia)
    • opnwatr.ioWhat if you could see what was going on in your brain or body with the detail of a high resolution camera or MRI machine in a simple wearable?  Openwater is creating a device that can enable us to see inside our brains or bodies in great detail.  With this comes the promise of new abilities to diagnose and treat disease and well beyond – communicating with thought alone.
    • More work on abstract cover. Pretty much done, though a rewording is in order. Something about fake news rather than Trump v Clinton, I think AbstractCover

7:00 – 8:30 Research

  • Working on the new version of the HCIC  boaster
  • Abstract: AbstractCover Add a picture of a network next to each item that reflects the polarization level. Maybe gray out the non-abstract bits.

  • Reworking the poster using the research browser and found this:
    • Emergence of metapopulations and echo chambers in mobile agents. Just from reading the abstract, their model is more complex, but similar results? Multi-agent models often describe populations segregated either in the physical space, i.e. subdivided in metapopulations, or in the ecology of opinions, i.e. partitioned in echo chambers. Here we show how both kinds of segregation can emerge from the interplay between homophily and social influence in a simple model of mobile agents endowed with a continuous opinion variable. In the model, physical proximity determines a progressive convergence of opinions but differing opinions result in agents moving away from each others. This feedback between mobility and social dynamics determines the onset of a stable dynamical metapopulation scenario where physically separated groups of like-minded individuals interact with each other through the exchange of agents. The further introduction of confirmation bias in social interactions, defined as the tendency of an individual to favor opinions that match his own, leads to the emergence of echo chambers where different opinions coexist also within the same group. We believe that the model may be of interest to researchers investigating the origin of segregation in the offline and online world.

8:30 – 5:00 BRC

  • Spent most of the day getting the development environment up and running on all the code.
  • Built a ‘dev file’ that fits on a thumb drive and contains versions of all the dev tools, SDKs and libraries. Was hampered by very slow internet. The workstation should go quicker as a result, though
  • Meeting with Theresa, Bob, Shawn, Aaron and Ellis. I think we laid out the dev process and it’s associated constraints. Shawn will go get us data to characterize, and Eli will get some ICU(?) data containing ICD codes.

  • Meetings. All. Day. Long.
  • Finished transferring Aaron’s ppt to LaTex. Looks pretty good, and an excellent first draft
    • We need to publish as a baseline to reference for our methods and choices. If it makes it through the review process, then we can point to it when we’re called out like in this morning’s review
