  • BP&S is up! Need to ping Antonio
  • Need to fix DfS to de-emphasize the mapping part. Including things like, uh, changing the title…
  • Pix at HQ – Done
  • Greenbelt today, which means getting Panda3D up and running on my laptop – Done. Had to point the IDE at the python in the install.
  • Need to add some thoughts to JuryRoom concepts
  • Send dungeon invites for the 23rd, and ping Aaron M. Done. Wayne can’t make it! Drat!
  • Dissertation working on the Bacharach section
  • Got the sim working on the laptop. I realize that the reaction wheel can be modeled as weights on a stick. Long discussion with Bruce T

  • BP&S is “on hold” in ArXiv. Hoping that it’s overlap with DfS. I took the mapping text out of the DfS paper and resubmitted. Once that’s done I can send Antonio a link and get advice.
  • Code review with Chris
  • Contact David and see if he’s ok with July 23 – Nope. Trying Aaron M. as a replacement
  • More dissertation. Folded in most of the BP&S paper
  • Look! More mapping of latent spaces! Unsupervised word embeddings capture latent knowledge from materials science literature41586_2019_1335_fig4_esm
    • Here we show that materials science knowledge present in the published literature can be efficiently encoded as information-dense word embeddings11,12,13 (vector representations of words) without human labelling or supervision. Without any explicit insertion of chemical knowledge, these embeddings capture complex materials science concepts such as the underlying structure of the periodic table and structure–property relationships in materials. Furthermore, we demonstrate that an unsupervised method can recommend materials for functional applications several years before their discovery. This suggests that latent knowledge regarding future discoveries is to a large extent embedded in past publications. Our findings highlight the possibility of extracting knowledge and relationships from the massive body of scientific literature in a collective manner, and point towards a generalized approach to the mining of scientific literature.
  • More Panda3D
    • Intervals and sequences
    • Panda3D forum
    • Programming with Panda3D
      • Well, this is looking a lot like the way I would have written it
      • You can convert a NodePath into a “regular” pointer at any time by calling nodePath.node(). However, there is no unambiguous way to convert back. That’s important: sometimes you need a NodePath, sometimes you need a node pointer. Because of this, it is recommended that you store NodePaths, not node pointers. When you pass parameters, you should probably pass NodePaths, not node pointers. The callee can always convert the NodePath to a node pointer if it needs to.
      • Nodepath
    • Huh. It looks like there is no support for procedurally generated primitives. Well, I know what I’m going to be doing…
      • Origin – done
      • Grid
      • Cube (x, y, z size), color (texture?), Boolean for endcaps
      • Cylinder (radius+steps, length), color
      • Sphere  (radius+steps), color
      • Skybox (texture)
      • Then try making a satellite from parts
    • JuryRoom Meeting
      • A lot of discussion on UI issues – how to vote for/against, the right panel layout, and the questions that should be asked for Chris’ studyCapture

  • Read and commented on Shimei’s proposal. It’s interesting to see how she’s weaving all these smaller threads together into one larger narrative. I find that my natural approach is to start with an encompassing vision and figure out how to break it down into its component parts. Which sure seems like stylistic vs. primordial. Interestingly, this implies that stylistic is more integrative? Transdisciplinary, primordial work, because it has no natural home, is more disruptive. It makes me think of this episode of Shock of the New about Paul Cezanne.
  • Working on getting BP&S into one file for ArXiv, then back to the dissertation.
    • Flailed around with some package mismatches, and had a upper/lowercase (.PNG vs. .png) problem. Submitted!
  • Need to ping Antonio about BP&S potential venues
  • The Redirect Method uses Adwords targeting tools and curated YouTube videos uploaded by people all around the world to confront online radicalization. It focuses on the slice of ISIS’ audience that is most susceptible to its messaging, and redirects them towards curated YouTube videos debunking ISIS recruiting themes. This open methodology was developed from interviews with ISIS defectors, respects users’ privacy and can be deployed to tackle other types of violent recruiting discourses online.
  • Pushed TimeSeriesML to the git repo, so we’re redundently backed up. Did not send data yet
  • Starting on the PyBullet tutorial
    • Trying to install pybullet.
      • Got this error: error: command ‘C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe’ failed with exit status 1158
      • Updating my Visual Studio (suggested here), in the hope that it fixes that. Soooooo Slooooow
      • Link needs rc.exe/rc.dll
      • Copied the most recent rc.exe and rcdll.dll (from into C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\
      • Giving up
  • Trying Panda3d
    • Downloaded and ran the installer. It couldn’t tell that I had Python 3.7.x, but otherwise was fine. Maybe that’s because my Python is on my D: drive?
    • Ran:
      pip install panda3d==1.10.3

      Which worked just fine

    • Had to add the D:\Panda3D-1.10.3-x64\bin and D:\Panda3D-1.10.3-x64\panda3d to the path to get all the imports to work right. This could be because I’m using a global, separately installed Python 3.7.x
    • Hmmm. Getting ModuleNotFoundError: No module named ‘panda3d.core.Point3’; ‘panda3d.core’ is not a package. The IDE can find it though….
    • In a very odd sequence of events, I tried using
      • from pandac.PandaModules import Point3, which worked, but gave me a deprecated warning.
    • Then, while fooling around, I tried the preferred
      • from panda3d.core import Point3, which now works. No idea what fixed it. Here’s the config that I’m using to run: Panda3dConfig
    • Nice performance, too: Pandas3D
    • And it has bullet in it, so maybe it will work here?
    • Starting on the manual

  • Got a desk reject from JASSS. Finding a home for this is turning out to be hard
  • Adjust Belief Places and Spaces for a straight ArXiv submission (article, endquote, fix cites). I’m doing this partially out of spite – I don’t want to see JASSS looking back at me in my svn repo. But I also need to get all the parts fixed so that it can be folded into the dissertation. \citep doesn’t play well, and I need to replace all the quotes with \enquote{}.
  • Start folding BP&S into dissertation
  • Look for Collective Intelligence venue?
  • Updated Pandas, which was where I got hung on Tuesday. Now I can use DataFrame.to_numpy() instead of Dataframe.values
  • Continuing on TimeSeriesNormalizer – done! Below is the original file with the data in columns (left) and the normalized file with the data in rows (right): Normalized
  • Learning about PyBullet
  • Thought for the day. Find the snippet for each room/group with the most positive and most negative sentiment, and use that instead of the three words.

Continuing with the ICML 2019 Tutorial: Recent Advances in Population-Based Search for Deep Neural Networks. Wow. Lots of implications for diversity science. They need to read Martindale though.

This also looks good, using the above concepts of Quality Diversity to create map-like structures in low dimensions

  • Autonomous skill discovery with Quality-Diversity and Unsupervised Descriptors
    • Quality-Diversity optimization is a new family of optimization algorithms that, instead of searching for a single optimal solution to solving a task, searches for a large collection of solutions that all solve the task in a different way. This approach is particularly promising for learning behavioral repertoires in robotics, as such a diversity of behaviors enables robots to be more versatile and resilient. However, these algorithms require the user to manually define behavioral descriptors, which is used to determine whether two solutions are different or similar. The choice of a behavioral descriptor is crucial, as it completely changes the solution types that the algorithm derives. In this paper, we introduce a new method to automatically define this descriptor by combining Quality-Diversity algorithms with unsupervised dimensionality reduction algorithms. This approach enables robots to autonomously discover the range of their capabilities while interacting with their environment. The results from two experimental scenarios demonstrate that robot can autonomously discover a large range of possible behaviors, without any prior knowledge about their morphology and environment. Furthermore, these behaviors are deemed to be similar to handcrafted solutions that uses domain knowledge and significantly more diverse than when using existing unsupervised methods.

Phil 7/1/19

7:00 –  6:00 ASRC

  • Updated ADP Job performance
  • Submitted JASSS Paper
  • Discovered the ComSES Network. It’s a repository for models, a job board, and a schedule with deadlines for ABM-related conferences and workshops!
  • First Tymora run with the map today!
    • It went well, I think. My main takeaway is that the place terms are working fine, but the space terms may need more context. It may be that an excerpt from the story that reflects the most common terms may be better than the terms in isolation.
    • The players stayed away from the stairs, and actually turned them to their advantage, using them as a defensive position.
    • The players went through the orb room very fast, and seemed to base their thinking on aspects of the map.
    • The crypticness of the map seems to help the games aspects. The terms are interpretable, and the ambiguity supports the agency of the players

  • What use are computational models of cognitive processes?
    • Computational modelers are not always explicit about their motivations for constructing models, nor are they always explicit about the theoretical implications of their models once constructed. Perhaps in part due to this, models have been criticized as “black-box” exercises which can play little or no role in scientific explanation. This paper argues that models are useful, and that the motivations for constructing computational models can be made clear by considering the roles that tautologies can play in the development of explanatory theories. From this, additionally, I propose that although there are diverse benefits of model building, only one class of benefits — those which relate to explanation — can provide justification for the activity.
  • DTW run looks good. It took 8 1/2 hours to run: fulldtw
  • Fixed a lot of things to get the clustering to behave, but it all looks good

  • Style Transfer in Text: Exploration and Evaluation
    • The ability to transfer styles of texts or images, is an important measurement of the advancement of artificial intelligence (AI). However, the progress in language style transfer is lagged behind other domains, such as computer vision, mainly because of the lack of parallel data and reliable evaluation metrics. In response to the challenge of lacking parallel data, we explore learning style transfer from non-parallel data. We propose two models to achieve this goal. The key idea behind the proposed models is to learn separate content representations and style representations using adversarial networks. Considering the problem of lacking principle evaluation metrics, we propose two novel evaluation metrics that measure two aspects of style transfer: transfer strength and content preservation. We benchmark our models and the evaluation metrics on two style transfer tasks: paper-news title transfer, and positive-negative review transfer. Results show that the proposed content preservation metric is highly correlate to human judgments, and the proposed models are able to generate sentences with similar content preservation score but higher style transfer strength comparing to autoencoder.
  • Different Spirals of Sameness: A Study of Content Sharing in Mainstream and Alternative Media
    • In this paper, we analyze content sharing between news sources in the alternative and mainstream media using a dataset of 713K articles and 194 sources. We find that content sharing happens in tightly formed communities, and these communities represent relatively homogeneous portions of the media landscape. Through a mix-method analysis, we find several primary content sharing behaviors. First, we find that the vast majority of shared articles are only shared with similar news sources (i.e. same community). Second, we find that despite these echo-chambers of sharing, specific sources, such as The Drudge Report, mix content from both mainstream and conspiracy communities. Third, we show that while these differing communities do not always share news articles, they do report on the same events, but often with competing and counter-narratives. Overall, we find that the news is homogeneous within communities and diverse in between, creating different spirals of sameness.
  • Fear of missing out, or FOMO, is “a pervasive apprehension that others might be having rewarding experiences from which one is absent”.[2] This social anxiety[3] is characterized by “a desire to stay continually connected with what others are doing”.[2] FOMO is also defined as a fear of regret,[4] which may lead to a compulsive concern that one might miss an opportunity for social interaction, a novel experience, a profitable investment, or other satisfying events.[5] In other words, FOMO perpetuates the fear of having made the wrong decision on how to spend time since “you can imagine how things could be different”.
  • In financial panics, when social facts dominate over objective ones, the behavior is still called herding.
  • More JASS paper
    • Finished implementing Wayne’s suggestions
