  • Bills
  • Get oil change kit from Bob’s
  • Antonio paper – done first complete pass
  • Sent Wayne a note to see if he knows of any online D&D research. My results are thin (see below)
  • Nice chat with Aaron about mapping in the D&D space. We reiterated that the goal of the first paper should be able to do the following:
    • map a linear dungeon
    • map the belief space adjacent to the dungeon (PC debates to consensus on how to proceed)
    • map the space in an open dungeon
    • map the belief space adjacent to an open dungeon
    • Additionally, we should be able to show that diversity (or lack of it) is recognizable. A mixed party should have a broader lexical set than a party of only fighters
    • We also realized that mapping could be a very good lens for digital anthropology. An interesting follow on paper could be an examination of how users run through a known dungeon, such as The Tomb of Horrors to see how the map generates, and to compare that to a version where the names of the items have been disguised so it’s not obvious that it’s the same game
  • Ordered these books. There doesn’t seem to be much else in the space, so I’m curious about the reference section
    • Second Person: Role-Playing and Story in Games and Playable Media (MIT Press)
      • Games and other playable forms, from interactive fictions to improvisational theater, involve role playing and story—something played and something told. In Second Person, game designers, authors, artists, and scholars examine the different ways in which these two elements work together in tabletop role-playing games (RPGs), computer games, board games, card games, electronic literature, political simulations, locative media, massively multiplayer games, and other forms that invite and structure play.  Second Person—so called because in these games and playable media it is “you” who plays the roles, “you” for whom the story is being told—first considers tabletop games ranging from Dungeons & Dragons and other RPGs with an explicit social component to Kim Newman’s Choose Your Own Adventure-style novel Life’s Lottery and its more traditional author-reader interaction. Contributors then examine computer-based playable structures that are designed for solo interaction—for the singular “you”—including the mainstream hit Prince of Persia: The Sands of Time and the genre-defining independent production Façade. Finally, contributors look at the intersection of the social spaces of play and the real world, considering, among other topics, the virtual communities of such Massively Multiplayer Online Role Playing Games (MMORPGs) as World of Warcraft and the political uses of digital gaming and role-playing techniques (as in The Howard Dean for Iowa Game, the first U.S. presidential campaign game).
    • Third Person: Authoring and Exploring Vast Narratives (The MIT Press)
      • The ever-expanding capacities of computing offer new narrative possibilities for virtual worlds. Yet vast narratives—featuring an ongoing and intricately developed storyline, many characters, and multiple settings—did not originate with, and are not limited to, Massively Multiplayer Online Games. Thomas Mann’s Joseph and His Brothers, J. R. R. Tolkien’s Lord of the Rings, Marvel’s Spiderman, and the complex stories of such television shows as Dr. Who, The Sopranos, and Lost all present vast fictional worlds. Third Person explores strategies of vast narrative across a variety of media, including video games, television, literature, comic books, tabletop games, and digital art. The contributors—media and television scholars, novelists, comic creators, game designers, and others—investigate such issues as continuity, canonicity, interactivity, fan fiction, technological innovation, and cross-media phenomena. Chapters examine a range of topics, including storytelling in a multiplayer environment; narrative techniques for a 3,000,000-page novel; continuity (or the impossibility of it) in Doctor Who; managing multiple intertwined narratives in superhero comics; the spatial experience of the Final Fantasy role-playing games; World of Warcraft adventure texts created by designers and fans; and the serial storytelling of The Wire. Taken together, the multidisciplinary conversations in Third Person, along with Harrigan and Wardrip-Fruin’s earlier collections First Person and Second Person, offer essential insights into how fictions are constructed and maintained in very different forms of media at the beginning of the twenty-first century.
  • A Support System to Accumulate Interpretations of Multiple Story Timelines
    • The story base interpretation is subjectively summarised and segmented from the first-person viewpoint. However, we often need to objectively represent an entire image by integrated knowledge. Yet, this is a difficult task. We proposed a novel approach, named the synthetic evidential study (SES), for understanding and augmenting collective thought processes through substantiated thought by interactive media. In this study, we investigated the kind of data that can be obtained through the SES sessions as interpretation archives and whether the database is useful to understand multiple story timelines. For the purpose, we designed a machine-readable interpretation data format and developed support systems to create and provide data that are easy to understand. We conducted an experiment using the simulation of the projection phase in SES sessions. From the results, we suggested that a “meta comment” which was deepened interpretation comment by the others in the interpretation archives to have been posted when it was necessary to consider other participants’ interpretation to broaden their horizons before posting the comment. In addition, the construction of networks to represent the relationships between the interpretation comments enabled us to suggest the important comments by using the degree centrality.

  • Discrete hierarchical organization of social group sizes
    • The ‘social brain hypothesis’ for the evolution of large brains in primates has led to evidence for the coevolution of neocortical size and social group sizes, suggesting that there is a cognitive constraint on group size that depends, in some way, on the volume of neural material available for processing and synthesizing information on social relationships. More recently, work on both human and non-human primates has suggested that social groups are often hierarchically structured. We combine data on human grouping patterns in a comprehensive and systematic study. Using fractal analysis, we identify, with high statistical confidence, a discrete hierarchy of group sizes with a preferred scaling ratio close to three: rather than a single or a continuous spectrum of group sizes, humans spontaneously form groups of preferred sizes organized in a geometrical series approximating 3–5, 9–15, 30–45, etc. Such discrete scale invariance could be related to that identified in signatures of herding behaviour in financial markets and might reflect a hierarchical processing of social nearness by human brains.
  • Work on Antonio’s paper – good progress
  • Aaron added a lot of content to Belief Spaces, and we got together to discuss. Probably the best thing to come out of the discussion was an approach to the dungeons that at one end is an acyclic, directed, linear graph of connected nodes. The map will be a line, with any dilemma discussions connected with the particular nodes. At the other end is an open environment. In between are various open and closed graphs that we can classify with some level of complexity.
  • One of the things that might be interesting to examine is the distance between nodes, and how that affects behavior
  • Need to mention that D&D are among the oldest “digital residents” of the internet, with decades-old artifacts.

  • This looks like a Big Deal from Google – Working together to apply AI for social good
    • Google.org is issuing an open call to organizations around the world to submit their ideas for how they could use AI to help address societal challenges. Selected organizations will receive support from Google’s AI experts, Google.org grant funding from a $25M pool, credit and consulting from Google Cloud, and more.
    • We look forward to receiving your application on or before 11:59 p.m. PT on January 22, 2019, and we encourage you to apply early given that we expect high volume within the last few hours of the application window. Thank you!

  • Waiting for a response from Antonio
  • Meeting with Don at 9:00 to discuss BAA partnership.
    • Don is comfortable with being PI or co-PI, whichever works best. When we call technical POCs, we speak on his behalf
    • We discussed how he could participate with the development of theoretical models based on signed graph Laplacians creating structures that can move in belief space. He thinks the idea has merit, and can put in up to 30% of his time on mathematical models and writing
    • ASRC has already partnered with UMBC. ASRC would sub to UMBC
    • Ordinarily, IP is distributed proportional to the charged hours
    • Don has access to other funding vehicles that can support the Army BAA, but this would make things more complicated. These should be discussed if we can’t make a “clean” agreement that meets our funding needs
  • Pinged Brian about his defense.
  • Some weekend thoughts
    • Opinion dynamics systems describe how communication within a network occurs, but disregards the motion of the network as a whole. In cases when the opinions converge, the network is stiff.
    • Graph laplacians could model “othering” by having negative weights. It looks like these are known as signed laplacians, and useful to denote difference. The trick is to discover the equations of motion. How do you model a “social particle”?
  • Just discovered the journal Swarm Intelligence
    • Swarm Intelligence is the principal peer reviewed publication dedicated to reporting research and new developments in this multidisciplinary field. The journal publishes original research articles and occasional reviews on theoretical, experimental, and practical aspects of swarm intelligence. It offers readers reports on advances in the understanding and utilization of systems that are based on the principles of swarm intelligence. Emphasis is given to such topics as the modeling and analysis of collective biological systems; application of biological swarm intelligence models to real-world problems; and theoretical and empirical research in ant colony optimization, particle swarm optimization, swarm robotics, and other swarm intelligence algorithms. Articles often combine experimental and theoretical work.

  • Two unrelated thoughts.
    • A tangle could be made to heal if each transaction kept track of the transaction that verified it. If that transaction became unreachable for more than N heartbeats, then the transaction becomes unverified again. Not sure if the verifying transaction needs to track the other way. Being able to query the tangle for these “scars” seems like it should be useful.
    • A death threat is a unique form of dimension reduction, and should probably be tracked/tagged using both emergent topic modeling and hand-tuned heuristics

  • LSTM Encoder-Decoder with Adversarial Network for Text Generation from Keyword
    • Natural Language Generation (NLG), one of the areas of Natural Language Processing (NLP), is a difficult task, but it is also important because it applies to our lives. So far, there have been various approaches to text generation, but in recent years, approaches using artificial neural networks have been used extensively. We propose a model for generating sentences from keywords using Generative Adversarial Network (GAN) composed of a generator and a discriminator among these artificial neural networks. Specifically, the generator uses the Long Short-Term Memory (LSTM) Encoder-Decoder structure, and the discriminator uses the bi-directional LSTM with self-attention. Also, the keyword for input to the encoder of the generator is input together with two words similar to oneself. This method contributes to the creation of sentences containing words that have similar meanings to the keyword. In addition, the number of unique sentences generated increases and diversity can be increased. We evaluate our model with BLEU Score and loss value. As a result, we can see that our model improves the performance compared to the baseline model without an adversarial network.

  • Sprint review
  • Reading Meltdown: Why our systems fail and What we can do about it, and I found some really interesting work that relates to social conformity, flocking, stampeding and nomadic behaviors:
    • We show that a deviation from the group opinion is regarded by the brain as a punishment,” said the study’s lead author, Vasily Klucharev. And the error message combined with a dampened reward signal produces a brain impulse indicating that we should adjust our opinion to match the consensus. Interestingly, this process occurs even if there is no reason for us to expect any punishment from the group. As Klucharev put it, “This is likely an automatic process in which people form their own opinion, hear the group view, and then quickly shift their opinion to make it more compliant with the group view.” (Page 154)
      • Reinforcement Learning Signal Predicts Social Conformity
        • Vasily Klucharev
        • We often change our decisions and judgments to conform with normative group behavior. However, the neural mechanisms of social conformity remain unclear. Here we show, using functional magnetic resonance imaging, that conformity is based on mechanisms that comply with principles of reinforcement learning. We found that individual judgments of facial attractiveness are adjusted in line with group opinion. Conflict with group opinion triggered a neuronal response in the rostral cingulate zone and the ventral striatum similar to the “prediction error” signal suggested by neuroscientific models of reinforcement learning. The amplitude of the conflict-related signal predicted subsequent conforming behavioral adjustments. Furthermore, the individual amplitude of the conflict-related signal in the ventral striatum correlated with differences in conforming behavior across subjects. These findings provide evidence that social group norms evoke conformity via learning mechanisms reflected in the activity of the rostral cingulate zone and ventral striatum.
    • When people agreed with their peers’ incorrect answers, there was little change in activity in the areas associated with conscious decision-making. Instead, the regions devoted to vision and spatial perception lit up. It’s not that people were consciously lying to fit in. It seems that the prevailing opinion actually changed their perceptions. If everyone else said the two objects were different, a participant might have started to notice differences even if the objects were identical. Our tendency for conformity can literally change what we see. (Page 155)

      • Neurobiological Correlates of Social Conformity and Independence During Mental Rotation
        • Background

          When individual judgment conflicts with a group, the individual will often conform his judgment to that of the group. Conformity might arise at an executive level of decision making, or it might arise because the social setting alters the individual’s perception of the world.

          Methods

          We used functional magnetic resonance imaging and a task of mental rotation in the context of peer pressure to investigate the neural basis of individualistic and conforming behavior in the face of wrong information.Results

          Conformity was associated with functional changes in an occipital-parietal network, especially when the wrong information originated from other people. Independence was associated with increased amygdala and caudate activity, findings consistent with the assumptions of social norm theory about the behavioral saliency of standing alone.

          Conclusions

          These findings provide the first biological evidence for the involvement of perceptual and emotional processes during social conformity.

        • The Pain of Independence: Compared to behavioral research of conformity, comparatively little is known about the mechanisms of non-conformity, or independence. In one psychological framework, the group provides a normative influence on the individual. Depending on the particular situation, the group’s influence may be purely informational – providing information to an individual who is unsure of what to do. More interesting is the case in which the individual has definite opinions of what to do but conforms due to a normative influence of the group due to social reasons. In this model, normative influences are presumed to act through the aversiveness of being in a minority position
      • A Neural Basis for Social Cooperation
        • Cooperation based on reciprocal altruism has evolved in only a small number of species, yet it constitutes the core behavioral principle of human social life. The iterated Prisoner’s Dilemma Game has been used to model this form of cooperation. We used fMRI to scan 36 women as they played an iterated Prisoner’s Dilemma Game with another woman to investigate the neurobiological basis of cooperative social behavior. Mutual cooperation was associated with consistent activation in brain areas that have been linked with reward processing: nucleus accumbens, the caudate nucleus, ventromedial frontal/orbitofrontal cortex, and rostral anterior cingulate cortex. We propose that activation of this neural network positively reinforces reciprocal altruism, thereby motivating subjects to resist the temptation to selfishly accept but not reciprocate favors.

  • Reading the New Yorker piece How Russia Helped Swing the Election for Trump, about Kathleen Hall Jamieson‘s book Cyberwar: How Russian Hackers and Trolls Helped Elect a President—What We Don’t, Can’t, and Do Know. Some interesting points with respect to Adversarial Herding:
    • Jamieson’s Post article was grounded in years of scholarship on political persuasion. She noted that political messages are especially effective when they are sent by trusted sources, such as members of one’s own community. Russian operatives, it turned out, disguised themselves in precisely this way. As the Times first reported, on June 8, 2016, a Facebook user depicting himself as Melvin Redick, a genial family man from Harrisburg, Pennsylvania, posted a link to DCLeaks.com, and wrote that users should check out “the hidden truth about Hillary Clinton, George Soros and other leaders of the US.” The profile photograph of “Redick” showed him in a backward baseball cap, alongside his young daughter—but Pennsylvania records showed no evidence of Redick’s existence, and the photograph matched an image of an unsuspecting man in Brazil. U.S. intelligence experts later announced, “with high confidence,” that DCLeaks was the creation of the G.R.U., Russia’s military-intelligence agency.
    • Jamieson argues that the impact of the Russian cyberwar was likely enhanced by its consistency with messaging from Trump’s campaign, and by its strategic alignment with the campaign’s geographic and demographic objectives. Had the Kremlin tried to push voters in a new direction, its effort might have failed. But, Jamieson concluded, the Russian saboteurs nimbly amplified Trump’s divisive rhetoric on immigrants, minorities, and Muslims, among other signature topics, and targeted constituencies that he needed to reach.

  • Artificial Intelligence and Social Simulation: Studying Group Dynamics on a Massive Scale
    • Recent advances in artificial intelligence and computer science can be used by social scientists in their study of groups and teams. Here, we explain how developments in machine learning and simulations with artificially intelligent agents can help group and team scholars to overcome two major problems they face when studying group dynamics. First, because empirical research on groups relies on manual coding, it is hard to study groups in large numbers (the scaling problem). Second, conventional statistical methods in behavioral science often fail to capture the nonlinear interaction dynamics occurring in small groups (the dynamics problem). Machine learning helps to address the scaling problem, as massive computing power can be harnessed to multiply manual codings of group interactions. Computer simulations with artificially intelligent agents help to address the dynamics problem by implementing social psychological theory in data-generating algorithms that allow for sophisticated statements and tests of theory. We describe an ongoing research project aimed at computational analysis of virtual software development teams.

  • DARPA’s move follows the Pentagon’s June decision to launch a $1.7 billion Joint Artificial Intelligence Center, or JAIC (pronounced “Jake”), to promote collaboration on AI-related R&D among military service branches, the private sector, and academia. The challenge is to transform relatively smaller contracts and some prototype systems development into large scale field deployment.

    • Basically, Aaron and I think there is a spectrum of interaction that can occur in these systems. At one end is some kind of market, where communication is mediated through price, time, and convenience to the transportation user. At the other is a more top down, control system way of dealing with this. NIST RCS would be an example of this. In between these two extremes are control hierarchies that in turn interact through markets

  • Graph laplacian dissertation
    • The spectrum of the normalized graph Laplacian can reveal structural properties of a network and can be an important tool to help solve the structural identification problem. From the spectrum, we attempt to develop a tool that helps us to understand the network structure on a deep level and to identify the source of the network to a greater extent. The information about different topological properties of a graph carried by the complete spectrum of the normalized graph Laplacian is explored. We investigate how and why structural properties are reflected by the spectrum and how the spectrum changes when compairing different networks from different sources.

The first section presents the most important critical exponents and relations, as well as the field-theoretical formalism used in the text. The second section briefly addresses the question of scaling behavior at first-order phase transitions. In Sec. III the author looks at dynamical extensions of basic static classes, showing the effects of mixing dynamics and of percolation. The main body of the review begins in Sec. IV, where genuine, dynamical universality classes specific to nonequilibrium systems are introduced. Section V considers such nonequilibrium classes in coupled, multicomponent systems. Most of the known nonequilibrium transition classes are explored in low dimensions between active and absorbing states of reaction-diffusion-type systems. However, by mapping they can be related to the universal behavior of interface growth models, which are treated in Sec. VI. The review ends with a summary of the classes of absorbing-state and mean-field systems and discusses some possible directions for future research.
  • “The Government Spies Using Our Webcams:” The Language of Conspiracy Theories in Online Discussions
    • Conspiracy theories are omnipresent in online discussions—whether to explain a late-breaking event that still lacks official report or to give voice to political dissent. Conspiracy theories evolve, multiply, and interconnect, further complicating efforts to limit their propagation. It is therefore crucial to develop scalable methods to examine the nature of conspiratorial discussions in online communities. What do users talk about when they discuss conspiracy theories online? What are the recurring elements in their discussions? What do these elements tell us about the way users think? This work answers these questions by analyzing over ten years of discussions in r/conspiracy—an online community on Reddit dedicated to conspiratorial discussions. We focus on the key elements of a conspiracy theory: the conspiratorial agents, the actions they perform, and their targets. By computationally detecting agent–action–target triplets in conspiratorial statements, and grouping them into semantically coherent clusters, we develop a notion of narrative-motif to detect recurring patterns of triplets. For example, a narrative-motif such as “governmental agency–controls–communications” appears in diverse conspiratorial statements alleging that governmental agencies control information to nefarious ends. Thus, narrative-motifs expose commonalities between multiple conspiracy theories even when they refer to different events or circumstances. In the process, these representations help us understand how users talk about conspiracy theories and offer us a means to interpret what they talk about. Our approach enables a population-scale study of conspiracy theories in alternative news and social media with implications for understanding their adoption and combating their spread

  • If I’m charging my 400 hours today, then start putting together text prediction. I’d like to try the Google prediction series to see what happens. Otherwise, there are two things I’d like to try with LSTMs, since they take 2 coordinates as inputs
    • Use a 2D embedding space
    • Use NLP to get a parts-of-speech (PoS) analysis of the text so that there can be a (PoS, Word) coordinate.
    • Evaluate the 2 approaches on their ability to converge?
  • Coordinating with Antonio about workshops. It’s the 2019 version of this: International Workshop on Massively Multi-Agent Systems (MMAS2018) in conjunction with IJCAI/ECAI/AAMAS/ICML 2018

  • Last Friday, Aaron was told by division leadership (Mike M) that R&D is being terminated as of Jan 1st and to get on billable projects. This is going against our impression of how things were going, so it’s unclear what will actually happen. So I’m not looking for a job just yet… Personally, I blame putting a deposit down on this: Tesla3

      • Molecular biology offers breathtaking views of the parts and processes that undergird life and its evolution. It is vexing, then, that we seem unable to analytically grasp the principles that would make the nature of cellular phenotypes more intelligible and their control more deliberate. One can always blame insufficient knowledge, but we also entertain the idea that physics and chemistry need formal and conceptual enrichment from computer science to become an appropriate foundation for systems biology. This view arises from the belief that computation is a natural phenomenon, like gravity or boiling water. We need adequate formalisms and models to reason about computation in the wild.This view guides many of our lab’s interests, which span the development and application of rule-based formalisms for modeling complex systems of molecular interaction, causality in concurrent systems, the interplay between network growth and network dynamics, phenotypic plasticity and evolvability, learning, and aging. Our approach is computational and theoretical. In the past we also conducted experimental work using C. elegans as a model system. Outside collaborations are essential to our group. The size of our team can fluctuate considerably, as we chase grants in pursuit of our passions, not opportunistically. Read more about our research.

  • From The Atlantic – stampede end condition:
    • It is impossible at this moment to envisage the Republican Party coming back. Like a brontosaurus with some brain-eating disorder it might lumber forward in the direction dictated by its past, favoring deregulation of businesses here and standing up to a rising China there, but there will be no higher mental functioning at work. And so it will plod into a future in which it is detested in a general way by women, African Americans, recent immigrants, and the educated young as well as progressives pure and simple. It might stumble into a political tar pit and cease to exist or it might survive as a curious, decaying relic of more savage times and more primitive instincts, lashing out and crushing things but incapable of much else.
