- Continuing along the flocking line of thought, I’m wondering how similar a stampede is to a runaway echo chamber. In both cases, they work best if the ‘shared knowledge’ is simple and clear. In a stampede, the idea is reduced to its simplest base – run! Although there may have been a reason at the beginning, at some point the group runs because it is running. Stopping will get you trampled. The only way to escape a stampede is to peel away from the edges, but that may not b possible due to environmental constraints (e.g. walls). Once started, they are hard to stop and ‘have a mind of their own’.
- Added to the lit review folder for P&C considered harmful
- Working on CI 2017 poster, making it more visual. Took a wrong turn incorporating too much new data from the HCIC poster. Cleaning and simplifying.
Phil 6.6.17
Research about one hour
- Broke apart the assets for the CI 2017 poster V2. What about the relationships from the P&C considered harmful outline? That’s not in the abstract…

Research (2 hours)
- I am thinking about flocking as a form of group decision making under uncertainty., kind of like the Multi-armed bandit problem parallelized. So in this context:
- Explore: Assumption of unknown information
- Flocking: Assumption of incomplete information
- Exploit: Assumption of complete information

- 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:

- Also made good progress on the poster. Will need to re-run the text for LMN -done:

- 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.
9:00 – 4:00 BRI
- 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%
Phil 5.26.17
7:30 – 12:00 Research
- Finished the abstract page, I think. Nope – need to extend the text a bit:

- Starting on the Boaster part
- Read the words from the Boaster V2 into LMN, clicked search on a vector of “network model social create twitter sunstein validate ” and got this: Towards the Modeling of Behavioral Trajectories of Users in Online Social Media by Alessandro Bessi. Looking at his publications, he’s another twin.
- Looking for ‘flocking’ images. I found this work tracking users of Twitter in Manhattan. And this, too: iographica
- Graphing the history of Philosophy using DBpedia
12:30 – 4:00 BRC
- Wrote up stories for upcoming 2-week(!) sprints
- Long discussion with Bob and Aaron about SOMs

- 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.io: What 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

8:30 – 5:00 BRC
- Updated confluence page to have Ellis email and the documents he referenced
- Sprint grooming
- Thinking hard about self-organizing maps
- Wikipedia article
- Self-Organizing Maps with Google’s TensorFlow
- This is a demonstration of how a self-organizing map (SOM), also known as a Kohonen network, can be used to map high-dimensional data into a two-dimensional representation. For the sake of an easy visualization ‘high-dimensional’ in this case is 3D.
- A Self Organizing Map (SOM) Package in Python: (SOMPY)
- Kohonen’s Self Organizing Feature Maps (tutorial)
- Scholar search for Teuvo Kohonen’s work
- Teuvo Kohonen’s home page at Helsinki Institute

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

- Checking out Facebook’s deep text
- The FB paper Text Understanding from Scratch, based on Natural language processing (almost) from scratch
- Connected to Jira!!
- Ran the papers through the LMN tool and searched on Scholar. Found some interesting papers
- This also led to an interesting post from the OpenAI people about Generative Models, which is kind of what I’m doing, though mediated through agents so that they can be understood by humans/me
- Reading Natural Language Processing (Almost) from Scratch. Finished section 3.2
- Got Ellis brain dump. Building a confluence page for the analytics research
Phil 5.23.18
7:00 – 8:00 Research
- 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.
