An ant colony has memories that its individual members don’t have

  • Like a brain, an ant colony operates without central control. Each is a set of interacting individuals, either neurons or ants, using simple chemical interactions that in the aggregate generate their behaviour. People use their brains to remember. Can ant colonies do that?

I got invited to the TF Dev conference!

The HKS Misinformation Review is a new format of peer-reviewed, scholarly publication. Content is produced and “fast-reviewed” by misinformation scientists and scholars, released under open access, and geared towards emphasizing real-world implications. All content is targeted towards a specialized audience of researchers, journalists, fact-checkers, educators, policy makers, and other practitioners working in the information, media, and platform landscape.

  • For the essays, a length of 1,500 to 3,000 words (excluding footnotes and methodology appendix) is appropriate, but the HKS Misinformation Review will consider and publish longer articles. Authors of articles with more than 3,000 words should consult the journal’s editors before submission.

7:00 – ASRC GOES

  •  Dissertation
    • It looks like I fixed my LaTeX problems. I went to C:\Users\phil\AppData\Roaming\MiKTeX\2.9\tex\latex, and deleted the ifvtex folder. Re-ran, things installed, and all is better now
    • Slides
  • GOES
    • Pinged Isaac about the idea of creating scenarios that incorporate the NASA simulators
    • Meeting
  • GSAW
    • Slides
    • Speakers presenting in a plenary session are scheduled to speak for 15 minutes, with five additional minutes allowed for questions and answers from the audience
    • Our microphones work best when the antenna unit is clipped to a belt and the microphone is attached near the center of your chest.
    • We are NOT providing network capabilities such as WiFi. If you require WiFi, you are responsible for purchasing it from the hotel and ensuring that it works for the presentation.
    • Charts produced by the PC version of Microsoft PowerPoint 2013, 2016 or 365 are preferred
    • . In creating your slides, note that the presentation room is large and you should consider this in your selection of larger fonts, diagram size, etc. At a minimum, a 20-point font is recommended
  • GPT-2 – Maybe do something with Aaron today?

Phil 11.25.19

7:00 – 7:00 ASRC GOES

  • Dissertation – more discussion
    • Added Clark’s Grounding in communication to the lit review
    • Added more to the diversity section. Need to fold ecosystem thinking in
  • Evolver – get copied state nailed down
    • That seems to be working in the test harness:
      vzfunc[0]: Zfunc
      d1={'Zfunc': 2.5, 'Zfunc_function': 'plus_func', 'Zvals1': 1.0, 'Zvals2': 1.5}

    • Still not setting the values of the EvolveAxis History_list correctly when breeding genomes, I think
  • Fika – slides are done-ish
  • ML – seminar
    • Good point – I need to visit with each of the committee to walk them through the dissertation (possibly with slides?) some time in January. Also, use the conclusions to build a TL;DR version.
  • Meeting with Aaron – nope

 

Phil 11.7.19

7:00 – 5:00 ASRC GOES

  • Dissertation
  • ML+Sim
    • Save actual and inferred efficiency to excel and plot
    • Create an illustration that shows how the network is trained, validated against the sim, then integrated into the operating system. (maybe show a physical testbed for evaluation?)
    • Demo at the NSOF
      • Went ok. Next steps are a sufficiently realistic model that can interpret an actual malfunction
      • Put together a Google Doc/Sheet that has the common core elements that we can model most satellites (LEO, MEO, GEO, and HEO?). What are the common components between cubesats and the James Webb?
      • Detection of station-keeping failure is a possibility
      • Also, high-dynamic phases, like orbit injection might be low-ish fruit
    • Tomorrow, continue on the GPU assignment in the evolver

Phil10.29.19

7:00 – 5:00 ASRC GOES

  • Dissertation – more maps
  • CTO presentation at 2:00
    • Delayed a bit, but I think it went well. A lot of the things that Eric tried to put in place look to be resurfacing. I wonder if it will work this time?
  • Meeting with Wayne? Yep – got his signature! Need to email Nicole and see where this goes – done
  • Starting to negotiate the new-ish “expensive information” paper with Aaron M

Language

Capacity, Bandwidth, and Compositionality in Emergent Language Learning

  • Many recent works have discussed the propensity, or lack thereof, for emergent languages to exhibit properties of natural languages. A favorite in the literature is learning compositionality. We note that most of those works have focused on communicative bandwidth as being of primary importance. While important, it is not the only contributing factor. In this paper, we investigate the learning biases that affect the efficacy and compositionality of emergent languages. Our foremost contribution is to explore how capacity of a neural network impacts its ability to learn a compositional language. We additionally introduce a set of evaluation metrics with which we analyze the learned languages. Our hypothesis is that there should be a specific range of model capacity and channel bandwidth that induces compositional structure in the resulting language and consequently encourages systematic generalization. While we empirically see evidence for the bottom of this range, we curiously do not find evidence for the top part of the range and believe that this is an open question for the community.

Radiolab: Tit for Tat

  • In the early 60s, Robert Axelrod was a math major messing around with refrigerator-sized computers. Then a dramatic global crisis made him wonder about the space between a rock and a hard place, and whether being good may be a good strategy. With help from Andrew Zolli and Steve Strogatz, we tackle the prisoner’s dilemma, a classic thought experiment, and learn about a simple strategy to navigate the waters of cooperation and betrayal. Then Axelrod, along with Stanley Weintraub, takes us back to the trenches of World War I, to the winter of 1914, and an unlikely Christmas party along the Western Front.
    • Need to send a note for them to look into Axelrod’s “bully” saddle point

7:00 – ASRC GOES

  • Dissertation – Nearly done with the agent cartography section?
  • CTO Rehearsal – 10:30 – 12:00 done
  • ML Dinner – 4:30 fun! 20191028_173214
  • Meeting With Aaron M
    • More thinking about what to do with the paper. We decided to try for the CHI4EVIL workshop, and then try something like IEEE Spectrum. I think I’d like to reframe it around the concept of Expensive Information and Automation. Try to tie together AI weapons, spam filters, and deepfakes
      • Automation makes negotiation more difficult, locks in trajectories
      • Handing off responsibility to automation amplifies opportunities and destructive potential
      • OODA loop could be generalized if you look at it from the perspective of attention.

Phil 6.6.19

7:00 – 3:00 ASRC PM Summit

  • 75th anniversary of D-day 640px-Naval_Bombardments_on_D-Day
  • Research talk today at the conference. Much networking yesterday.
    • The talk went well. More opportunities for networking. Mayne some ML for 3D printing?
  • Copied the CHIPLAY paper to a new GROUP 2020 folder and change to the acm small article format
  • Simplicial models of social contagion
    • Complex networks have been successfully used to describe the spread of diseases in populations of interacting individuals. Conversely, pairwise interactions are often not enough to characterize social contagion processes such as opinion formation or the adoption of novelties, where complex mechanisms of influence and reinforcement are at work. Here we introduce a higher-order model of social contagion in which a social system is represented by a simplicial complex and contagion can occur through interactions in groups of different sizes. Numerical simulations of the model on both empirical and synthetic simplicial complexes highlight the emergence of novel phenomena such as a discontinuous transition induced by higher-order interactions. We show analytically that the transition is discontinuous and that a bistable region appears where healthy and endemic states co-exist. Our results help explain why critical masses are required to initiate social changes and contribute to the understanding of higher-order interactions in complex systems.
  • This is wild: Randomly wired neural networks and state-of-the-art accuracy? Yes it works.
  • This is sad: Training a single AI model can emit as much carbon as five cars in their lifetimes
  • Came home and slept 2 1/2 hours. Very cooked.

Phil5.23.19

7:00 – 5:00 ASRC GEOS

  • Saw 4×3000 with David and Roger last night. The VR lab seems to be a thing. Need to go down and have a chat, possibly about lists, stories, maps and games
  • Found the OECD Principles on Artificial Intelligence. I haven’t had a chance to actually *read* any of it, but I did create a “Treaty Lit” folder in the Sanhedrin folder and put pdf versions of them. I ran my tool over them and got the following probe:
    • state cyber cybercrime agree united china mechanism
  • Putting that into Google Scholar returns some good hits as well, though I haven’t gotten a chance to do anything beyond that.
  • JASSS paper
    • Changing “consensus” to “alignment”, and breaking many paragraphs. I think the setup of the space in the introduction is better now.
  • Got caught up on NESDIS. Worked some on the slide deck, which I finally got back. Scheduled a walkthrough with T tomorrow
  • GEOS AI/ML meeting at NSOF. Still trying to figure out roles and responsibilities. I think the Sanhedrin concept will help Bruce formalize our contributions.

Phil 5.16.18

7:00 – 9:00 ASRC GEOS/AIMES

  • Worked on the slides a bit
  • Adding changes to the JASSS paper
  • Waiting for meeting
