This document describes the Facebook Full URL shares dataset, resulting from a collaboration between Facebook and Social Science One. It is for Social Science One grantees and describes the dataset’s scope, structure, fields, and privacy-preserving characteristics. This is the second of two planned steps in the release of this “Full URLs dataset”, which we described at socialscience.one/blog/update-social-science-one.

Judging Truth

    • Deceptive claims surround us, embedded in fake news, advertisements, political propaganda, and rumors. How do people know what to believe? Truth judgments reflect inferences drawn from three types of information: base rates, feelings, and consistency with information retrieved from memory. First, people exhibit a bias to accept incoming information, because most claims in our environments are true. Second, people interpret feelings, like ease of processing, as evidence of truth. And third, people can (but do not always) consider whether assertions match facts and source information stored in memory. This three-part framework predicts specific illusions (e.g., truthiness, illusory truth), offers ways to correct stubborn misconceptions, and suggests the importance of converging cues in a post-truth world, where falsehoods travel further and faster than the truth.

The brains of birds synchronize when they sing duets

  • When a male or female white-browed sparrow-weaver begins its song, its partner joins in at a certain time. They duet with each other by singing in turn and precisely in tune. A team led by researchers from the Max Planck Institute for Ornithology in Seewiesen used mobile transmitters to simultaneously record neural and acoustic signals from pairs of birds singing duets in their natural habitat. They found that the nerve cell activity in the brain of the singing bird changes and synchronizes with its partner when the partner begins to sing. The brains of both animals then essentially function as one, which leads to the perfect duet. (original article: Duets recorded in the wild reveal that interindividually coordinated motor control enables cooperative behavior)

Bottom-Up and Top-Down Attention for Image Captioning and Visual Question Answering

  • Top-down visual attention mechanisms have been used extensively in image captioning and visual question answering (VQA) to enable deeper image understanding through fine-grained analysis and even multiple steps of reasoning. In this work, we propose a combined bottom-up and top down attention mechanism that enables attention to be calculated at the level of objects and other salient image regions. This is the natural basis for attention to be considered. Within our approach, the bottom-up mechanism (based on Faster R-CNN) proposes image regions, each with an associated feature vector, while the top-down mechanism determines feature weightings. Applying this approach to image captioning, our results on the MSCOCO test server establish a new state-of-the-art for the task, achieving CIDEr / SPICE / BLEU-4 scores of 117.9, 21.5 and 36.9, respectively. Demonstrating the broad applicability of the method, applying the same approach to VQA we obtain first place in the 2017 VQA Challenge

 

  •  Defense
    • Need to think about how to discuss maps like the T-O and belief space maps (flocking and stampeding projections?) are attention maps as well. Emphasizing well-triangulated but less-attended areas is a potential good. Compare to how maps opened up areas for exploration and exploitation, but this is constructive and not extractive

Direct Fit to Nature: An Evolutionary Perspective on Biological and Artificial Neural Networks

  • Evolution is a blind fitting process by which organisms become adapted to their environment. Does the brain use similar brute-force fitting processes to learn how to perceive and act upon the world? Recent advances in artificial neural networks have exposed the power of optimizing millions of synaptic weights over millions of observations to operate robustly in real-world contexts. These models do not learn simple, human-interpretable rules or representations of the world; rather, they use local computations to interpolate over task-relevant manifolds in a high-dimensional parameter space. Counterintuitively, similar to evolutionary processes, over-parameterized models can be simple and parsimonious, as they provide a versatile, robust solution for learning a diverse set of functions. This new family of direct-fit models present a radical challenge to many of the theoretical assumptions in psychology and neuroscience. At the same time, this shift in perspective establishes unexpected links with developmental and ecological psychology.

  • Social network proximity predicts similar trajectories of psychological states: Evidence from multi-voxel spatiotemporal dynamics put this in the lit review!
    • Temporal trajectories of multivoxel patterns capture meaningful individual differences.

    • Inter-subject similarity in pattern trajectories predicts social network proximity.

    • Friends may be exceptionally similar in how attentional states evolve over time.

    • There are distinct behavioral effects of neural response pattern and magnitude trajectories.

  • Irrational Politics, Unreasonable Culture: Justin Smith and Jessica Riskin held on January 29, 2020
    • Shouting and shaming, lying and trolling: How did we ever learn to speak to one another the way we do now? In matters political and cultural, public and private, on social media and in major newsrooms, it seems as though over the past few years a bizarre and frightening irrationality has taken hold of our discourse. But what is irrationality, and what is that thing—reason—with which we oppose it? 
    • Jessica Riskin is involved in some cross-cultural project at Stanford that is trying to bring the arts and STEM into closer orbits (techies and fuzzies?)? Send an email
    • Justin Smith is interested on the effects of algorithms on thinking. Can’t find any writing, but he gave a talk: “The Algorithmic Production of Social Kinds,” a lecture-performance at DAU, Paris, February 12, 2019.

  • The Office of Inspector General conducted a review of the Chicago Police Department’s risk models known as the Strategic Subject List and Crime and Victimization Risk Model. CPD received $3.8 million in federal grants to develop these models, which were designed to predict the likelihood an individual would become a “party to violence”, i.e. the victim or offender in a shooting. The results of SSL were know n as “risk scores” while CVRM produced “risk tiers.” In August 2079, CPD informed OIG that it intended to decommission its PTV risk model program and did so on November l, 2079. The purpose of this advisory is to assess lessons learned and provide recommendations for future implementation of PTV risk models.
  • In “Towards a Human-like Open-Domain Chatbot”, we present Meena, a 2.6 billion parameter end-to-end trained neural conversational model. We show that Meena can conduct conversations that are more sensible and specific than existing state-of-the-art chatbots. (Google blog post)

    • Influx DB (Influx 2.0) is a high-performance data store written specifically for time series data. It allows for high throughput ingest, compression and real-time querying. InfluxDB is written entirely in Go and compiles into a single binary with no external dependencies. It provides write and query capabilities with a command-line interface, a built-in HTTP API, a set of client libraries (e.g., Go, Java, and JavaScript) and plugins for common data formats such as Telegraf, Graphite, Collectd and OpenTSDB. 
    • The plan is to have the sim place data from the sim into the Influx DB and have the dashboard display the plots
    • This will generate data: file:///D:/GOES/AIMS4_UI_Mock/3satellite-instrument-analysis.html?page=reportpage&channel=5&status=error, once the demo is unzipped into D:/GOES
  • Meeting with Wayne
