• Stumbled on this podcast this morning: How Small Problems Snowball Into Big Disasters
• How to Prepare for a Crisis You Couldn’t Possibly Predict
• I’m trying to think about how this should be applied to human/machine ecologies. I think that simulation is really important because it lets one model patch compare itself against another model without real-world impacts. This has something to do with a shared, multi-instance environment simulation as well. The environment provides one level of transparent interaction, but there also needs to be some level of inadvertent social information that shows some insight into how a particular system is working.
• When the simulation and the real world start to diverge for a system, that needs to be signaled
• Systems need to be able to “look into” other simulations and compare like with like. So a tagged item (bicycle) in one sim is the same in another.
• Is there an OS that hands out environments?
• How does a decentralized system coordinate? Is there an answer in MMOGs?
• Kate Starbird’s presentation was interesting as always. We had a chance to talk afterwards, and she’d like to see our work, so I’ve sent her links to the last two papers.
I also met Bill Braniff, who is the director of the UMD Study of Terrorism and responses to Terrorism. He got papers too, with a brief description about how mapping could aid in the detection of radicalization patterns
Then at lunch, I had a chance to meet with Roger Bostelman from NIST. He’s interested in writing standards for fleet and swarm vehicles, and is interested in making sure that standards mitigate the chance of stampeding autonomous vehicles, so I sent him the Blue Sky draft.
And lastly, I got a phone call from Aaron who says that our project will be terminated December 31, after which there will be no more IR&D at ASRC. It was a nice run while it lasted. And they may change their minds, but I doubt it.

• Writing your own LaTex class
• Multiple facets of biodiversity drive the diversity–stability relationship
• A substantial body of evidence has demonstrated that biodiversity stabilizes ecosystem functioning over time in grassland ecosystems. However, the relative importance of different facets of biodiversity underlying the diversity–stability relationship remains unclear. Here we use data from 39 grassland biodiversity experiments and structural equation modelling to investigate the roles of species richness, phylogenetic diversity and both the diversity and community-weighted mean of functional traits representing the ‘fast–slow’ leaf economics spectrum in driving the diversity–stability relationship. We found that high species richness and phylogenetic diversity stabilize biomass production via enhanced asynchrony in the performance of co-occurring species. Contrary to expectations, low phylogenetic diversity enhances ecosystem stability directly, albeit weakly. While the diversity of fast–slow functional traits has a weak effect on ecosystem stability, communities dominated by slow species enhance ecosystem stability by increasing mean biomass production relative to the standard deviation of biomass over time. Our in-depth, integrative assessment of factors influencing the diversity–stability relationship demonstrates a more multicausal relationship than has been previously acknowledged.
• Computer Algorithms, Market Manipulation and the Institutionalization of High Frequency Trading (adversarial herding?)
• Karin Knorr Cetina is interested in financial markets, knowledge and information, as well as in globalization, theory and culture. Her current projects include a book on global foreign exchange markets and on post-social knowledge societies. She continues to do research on the information architecture of financial markets, on their “global microstructures” (the global social and cultural form these markets take) and on trader markets in contrast to producer markets. She also studies globalization from a microsociological perspective, using an ethnographic approach, and she continues to be interested in “laboratory studies,” the study of science, technology and information at the site of knowledge production – particularly in the life sciences and in particle physics.

• The Publisher’s Patron: How Google’s News Initiative Is Re-Defining Journalism
• Facebook, Twitter, Amazon and Google – many tech companies are involved in journalism. A major force, however, is Google’s News Initiative. But where does Google’s money go? We can reveal that the typical recipient of Google funding is a commercial legacy institution in Western Europe. Meanwhile, non-profit news organisations and public-service media rarely receive funding. The only question is: what is Google trying to achieve with its sponsorship?
• Introduction to Machine Learning for Coders: Launch
• Today we’re launching our newest (and biggest!) course, Introduction to Machine Learning for Coders. The course, recorded at the University of San Francisco as part of the Masters of Science in Data Science curriculum, covers the most important practical foundations for modern machine learning. There are 12 lessons, each of which is around two hours long—a list of all the lessons along with a screenshot from each is at the end of this post.
• There are some excellent machine learning courses already, most notably the wonderful Coursera course from Andrew Ng. But that course is showing its age now, particularly since it uses Matlab for coursework. This new course uses modern tools and libraries, including python, pandas, scikit-learn, and pytorch. Unlike many educational materials in the field, our approach is “code first” rather than “math first”. It’s well suited to people who are writing code every day, but perhaps aren’t practicing their math chops quite as often (although we do cover all the necessary theory when appropriate). Perhaps most importantly, this course is very opinionated—rather than being a complete survey of every type of model, we focus on those that really matter in practice.
• Been thinking about libraries being a marker for production code, and it strikes me that GitHub could be a set of “conversations”. There are markers for popularity (pulls), and markers for quality (pushes). We know how many people are contributing (plus followers and following), and there are tags. There is also a marketplace now.  There is also an API. My sense is that it should be possible to build maps of:
• Language relationships and use (X Y Z + color?)
• Relationships within languages?
• There are also other types of measures of consensus like dependency graphs (who’s actually using) and releases (more info here)

• This from the New Yorker book review of Network Propaganda: Manipulation, Disinformation, and Radicalization in American Politics
• The Clinton orgy-island story met a very different fate in the right-wing media, which pushed versions of it over the course of the campaign. (Fox News initially ran several segments that raised the topic of the “Lolita Express.”) The dynamic on the right, the authors found, “rewards the most popular and widely viewed channels at the very top of the media ecosystem for delivering stories, whether true or false, that protect the team, reinforce its beliefs, attack opponents, and refute any claims that might threaten ‘our’ team from outsiders.” Referring to the orgy-island story, the authors note that “not one right-wing outlet came out to criticize and expose this blatant lie for what it was. In the grip of the propaganda feedback loop, the right-wing media ecosystem had no mechanism for self-correction, and instead exhibited dynamics of self-reinforcement, confirmation, and repetition so that readers, viewers and listeners encountered multiple versions of the same story, over months, to the point that both recall and credibility were enhanced.”
• Transdisciplinary PhD Journeys: Reflecting on the challenge of the ‘transdisciplinary triple jump’
• Responding to calls to ‘be transdisciplinary4’, we have committed to applying and critically reflecting on the principles of TD in our PhD research. However, in current institutional structures and cultures of academia, this adds an additional challenge to the existing demands of PhD research5,6. Not only are we expected to navigate the terrain of interdisciplinarity described as an ‘undisciplinary journey’6 which requires ‘epistemological agility’, but we are also confronted with the task of engaging meaningfully with societal actors beyond our academic comfort zones. All of this means we are constantly trying to ‘be everything to everyone’ and risk burning ourselves out in the process.

• “Who’s idea was it to connect every idiot on the internet with every other idiot” PJ O’Rourke, Commonwealth Club, 2018
• Running Programs In Reverse for Deeper A.I.” by Zenna Tavares
• In this talk I show that inverse simulation, i.e., running programs in reverse from output to input, lies at the heart of the hardest problems in both human cognition and artificial intelligence. How humans are able to reconstruct the rich 3D structure of the world from 2D images; how we predict that it is safe to cross a street just by watching others walk, and even how we play, and sometimes win at Jenga, are all solvable by running programs backwards. The idea of program inversion is old, but I will present one of the first approaches to take it literally. Our tool ReverseFlow combines deep-learning and our theory of parametric inversion to compile the source code of a program (e.g., a TensorFlow graph) into its inverse, even when it is not conventionally invertible. This framework offers a unified and practical approach to both understand and solve the aforementioned problems in vision, planning and inference for both humans and machines.
• Bot-ivistm: Assessing Information Manipulation in Social Media Using Network Analytics
• Matthew Benigni
• Kenneth Joseph
• Kathleen M. Carley (Scholar)
• Social influence bot networks are used to effect discussions in social media. While traditional social network methods have been used in assessing social media data, they are insufficient to identify and characterize social influence bots, the networks in which they reside and their behavior. However, these bots can be identified, their prevalence assessed, and their impact on groups assessed using high dimensional network analytics. This is illustrated using data from three different activist communities on Twitter—the “alt-right,” ISIS sympathizers in the Syrian revolution, and activists of the Euromaidan movement. We observe a new kind of behavior that social influence bots engage in—repetitive @mentions of each other. This behavior is used to manipulate complex network metrics, artificially inflating the influence of particular users and specific agendas. We show that this bot behavior can affect network measures by as much as 60% for accounts that are promoted by these bots. This requires a new method to differentiate “promoted accounts” from actual influencers. We present this method. We also present a method to identify social influence bot “sub-communities.” We show how an array of sub-communities across our datasets are used to promote different agendas, from more traditional foci (e.g., influence marketing) to more nefarious goals (e.g., promoting particular political ideologies).

It’s fully integrated with Google Cloud Storage and can handle datasets as large as tens of billions of event records. If you store any time series data in Cloud Storage, you can use the Cloud Inference API to begin generating predictions.
• Realized that there are additional matrices that can post-multiply the Laplacian. That way we can break down the individual components that contribute to “stiffness”. The reason for this is that only identical oscillators will synchronize. Similarity is a type of implicit coordination

• There can also be a Weight vector W: which contains the “mass” of the node. A high mass node will be more influential in the network.
• Had a few thoughts about JuryRoom self governance. The major social networks seem to be a mess with respect to what rights users have, and what constitutes a violation of terms of service. The solutions seem pretty brittle (Radiolab podcast on facebook rule making). JuryRoom has built in a mechanism for deliberation. Can that be used to create an online legal framework for crowdsourcing the rules and the interpretation? Roughly, I think that this requires the following:
• A constitution – a simple document that lays out how JuryRoom will be goverened.
• A bill of rights. What are users entitled to?
• The concept of petition, trial, binding decisions, and precedent.
• Is there a concept of testifying under oath?
• The addition of “evidence” attachments that can be linked to posts. This could be existing documents, commissioned expert opinion, etc.
• A special location for the “legal decisions”. These will become the basis for the precedent in future deliberations. Links to these prior decisions are done as attachments? Or as something else?
• Localization. Since what is acceptable (within the bounds of the constitution and the bill of rights) changes as a function of culture, there needs to be a way that groups can split off from the main group to construct and use their own legal history. Voting/membership may need to be a part of this.

• According to personality psychology, personality traits determine many aspects of human behaviour. However, validating this insight in large groups has been challenging so far, due to the scarcity of multi-channel data. Here, we focus on the relationship between mobility and social behaviour by analysing trajectories and mobile phone interactions of 1000 individuals from two high-resolution longitudinal datasets. We identify a connection between the way in which individuals explore new resources and exploit known assets in the social and spatial spheres. We show that different individuals balance the exploration-exploitation trade-off in different ways and we explain part of the variability in the data by the big five personality traits. We point out that, in both realms, extraversion correlates with the attitude towards exploration and routine diversity, while neuroticism and openness account for the tendency to evolve routine over long time-scales. We find no evidence for the existence of classes of individuals across the spatio-social domains. Our results bridge the fields of human geography, sociology and personality psychology and can help improve current models of mobility and tie formation.

• My current research is on the sociology of markets, focusing on automated trading. I’ve worked in the past on topics ranging from the sociology of nuclear weapons to the meaning of proof in the context of computer systems critical to safety or security.
• Computer algorithms are playing an ever more important role in financial markets. This paper proposes and exemplifies a sociology of algorithms that is (i) historical, in that it demonstrates path-dependence in the development of automated markets; (ii) ecological (in Abbott’s sense), in that it shows how automated high-frequency trading (HFT) is both itself an ecology and also is shaped by other linked ecologies (especially those of trading venues and of regulation); and (iii) “Zelizerian,” in that it highlights the importance of boundary work, especially of efforts to distinguish between (in effect) “good” and “bad” actors and algorithms. Empirically, the paper draws on interviews with 43 practitioners of HFT, and on a wider historical-sociology study (including interviews with a further 44 people) of the development of trading venues. The paper investigates the practices of HFT and analyses (in historical, ecological, and “Zelizerian” terms) how these differ in three different contexts (two types of share trading and foreign exchange).

• Controlling the Information Flow: Effects on Consumers’ Decision Making and Preferences
• One of the main objectives facing marketers is to present consumers with information on which to base their decisions. In doing so, marketers have to select the type of information system they want to utilize in order to deliver the most appropriate information to their consumers. One of the most interesting and distinguishing dimensions of such information systems is the level of control the consumer has over the information system. The current work presents and tests a general model for understanding the advantages and disadvantages of information control on consumers’ decision quality, memory, knowledge, and confidence. The results show that controlling the information flow can help consumers better match their preferences, have better memory and knowledge about the domain they are examining, and be more confident in their judgments. However, it is also shown that controlling the information flow creates demands on processing resources and therefore under some circumstances can have detrimental effects on consumers’ ability to utilize information. The article concludes with a summary of the findings, discussion of their application for electronic commerce, and suggestions for future research avenues.

•  The Greeks had experts determine choices, and the public vote between the expert choices
• A satisfactory model of decision-making in an epistemic democracy must respect democratic values, while advancing citizens’ interests, by taking account of relevant knowledge about the world. Analysis of passages in Aristotle and legislative process in classical Athens points to a “middle way” between independent-guess aggregation and deliberation: an epistemic approach to decision-making that offers a satisfactory model of collective judgment that is both time-sensitive and capable of setting agendas endogenously. By aggregating expertise across multiple domains, Relevant Expertise Aggregation (REA) enables a body of minimally competent voters to make superior choices among multiple options, on matters of common interest. REA differs from a standard Condorcet jury in combining deliberation with voting based on judgments about the reputations and arguments of domain-experts.

How intermittent breaks in interaction improve collective intelligence

• Many human endeavors—from teams and organizations to crowds and democracies—rely on solving problems collectively. Prior research has shown that when people interact and influence each other while solving complex problems, the average problem-solving performance of the group increases, but the best solution of the group actually decreases in quality. We find that when such influence is intermittent it improves the average while maintaining a high maximum performance. We also show that storing solutions for quick recall is similar to constant social influence. Instead of supporting more transparency, the results imply that technologies and organizations should be redesigned to intermittently isolate people from each other’s work for best collective performance in solving complex problems.

Detecting signs of dementia using word vector representations

• Recent approaches to word vector representations, e.g., ‘w2vec’ and ‘GloVe’, have been shown to be powerful methods for capturing the semantics and syntax of words in a text. The approaches model the co-occurrences of words and recent successful applications on written text have shown how the vector representations and their interrelations represent the meaning or sentiment in the text. Most applications have targeted written language, however, in this paper, we investigate how these models port to the spoken language domain where the text is the result of (erroneous) automatic speech transcription. In particular, we are interested in the task of detecting signs of dementia in a person’s spoken language. This is motivated by the fact that early signs of dementia are known to affect a person’s ability to express meaning articulately for example when they engage in a conversation – something which is known to be cognitively very demanding. We analyse conversations designed to probe people’s short and long-term memory and propose three different methods for how word vectors may be used in a classification setup. We show that it is possible to identify dementia from the output of a speech recognizer despite a high occurrence of recognition errors.

Trust in Organizations: Frontiers of Theory and Research

• Although its importance is readily apparent, the contours of trust in collective contexts are much less obvious. The decision to trust in collective settings is different from, and in many respects more problematic than, decisions about trust that arise in other social contexts. Because of the size and structural complexity of large organizations, for example, individuals do not have the opportunity to engage in the sort of incremental and repeated exchanges that have been shown to facilitate the development of trust in more intimate settings, such as dyadic relationships

• generic, scalable and decentralized fault detection for robot swarms
• Robot swarms are large-scale multirobot systems with decentralized control which means that each robot acts based only on local perception and on local coordination with neighboring robots. The decentralized approach to control confers number of potential benefits. In particular, inherent scalability and robustness are often highlighted as key distinguishing features of robot swarms compared with systems that rely on traditional approaches to multirobot coordination. It has, however, been shown that swarm robotics systems are not always fault tolerant. To realize the robustness potential of robot swarms, it is thus essential to give systems the capacity to actively detect and accommodate faults. In this paper, we present a generic fault-detection system for robot swarms. We show how robots with limited and imperfect sensing capabilities are able to observe and classify the behavior of one another. In order to achieve this, the underlying classifier is an immune system-inspired algorithm that learns to distinguish between normal behavior and abnormal behavior online. Through a series of experiments, we systematically assess the performance of our approach in a detailed simulation environment. In particular, we analyze our system’s capacity to correctly detect robots with faults, false positive rates, performance in a foraging task in which each robot exhibits a composite behavior, and performance under perturbations of the task environment. Results show that our generic fault-detection system is robust, that it is able to detect faults in a timely manner, and that it achieves a low false positive rate. The developed fault-detection system has the potential to enable long-term autonomy for robust multirobot systems, thus increasing the usefulness of robots for a diverse repertoire of upcoming applications in the area of distributed intelligent automation.

• At least keep track of the last N (or whole history?) of chromosome so that the principal components can be analyzed.
• By comparing the states over time, we could find the states adjacent to problem states?

Implementing Feedback for ABM Meta-Modeling
Karan Budhraja and Tim Oates

PINCH: Self-Organized Context Neighborhoods for Smart Environments
Chenguang Liu, Christine Julien and Amy L. Murphy

• Neighborhood mesh networks
• everything is stored in a small beacon that is cooperatively shared in the neighborhood

A QoS-aware Adaptive Mobility Handling Approach for LoRa-based IoT Systems
Robbe Berrevoets and Danny Weyns

Reins-MAC: Firefly Inspired Communication Scheduling for Reliable Low-Power Wireless

• Sensors on UAVs
• Electro-optic
• Hyper-spectral(?)
• Sensors are not the problem, bandwidth is
• Selecting the relevant information
• Attention – which parts of the signal are important
• Autoencoder NN – it’s like dropout?
• Split domain stacked cnn. The front half (encoder) NN encodes the data and transmits the “compressed” data from the hidden layer to the back half of the NN.

Goal-aware Team Affiliation in Collectives of Autonomous Robots
Lukas Esterle

• Teamwork in nature
• stampedes!
• Observer/follower == explore/exploit
• They did use the multi-armed bandit framework as a learning system.
• Real world implementation is intruder detection and response

Optimizing Transitions Between Abstract ABM Demonstrations (video presentation)
Brian Seipp, Karan Budhraja and Tim Oates

• What is the optimal path that connects two behaviors
• Traverse a behavior coordinate space
• Getting from a start image to a goal image. The image can “mean” many things. Agents provide the mapping?
• Intermediate states are shown
• Noise added to guarantee convergence?

Self-organized Resource Allocation for Reconfigurable Robot Ensembles
Julian Hanke, Oliver Kosak, Alexander Schiendorfer and Wolfgang Reif

• Search – determine dangers
• Continual observe
• React
• This is a fitness space analysis based on optimal configuration of robots for a given task. It’s kind of a distributed traveling salesman problem combined with a market and a bidder as a way of merging the distributed solution. I wonder if it is computationally better than a GA solution. It could be a way of looking at hyperparameter tuning?
• Not clear that it can handle a floating point value, like fuel level
• The goal is for the allocation to be fast

Panel: The Future of Autonomic Computing and Self-* Systems:

• Kristie Bellman – some success but in isolated, hard to define areas. Build foundation of principals that can be used to frame development
• Ada Diaconescu – Efficiency-oriented or creativity-oriented self* systems
• Simon Dobson – We have turned a lot of fields into computation. But – AI told us nothing about how people play Go. We’re trying to build, not describe
• Xiaohui (Helen) Gu – AIOps, bridging the gap between academia and industry
• Arif Merchant – (Google) Missing holistic, end-to-end solutions. First and follow-on principals.
• Danny Weyns – Be less ad-hoc and more scientific. Address threats to validity. Solid foundations.
• I talked a bit about the continuum from the low-hanging fruit of autonomic systems to the difficult task of creating self-aware systems.

A Macro-Level Order Metric for Self-Organizing Adaptive Systems
David King and Gilbert Peterson

• critical and stable states, based on local and global entropy
• I think that he is talking about “personalized” entropy rather than “local” entropy.

A Self-Organized Learning Model for Anomalies Detection: Application to Elderly People
Nicolas Verstaevel, Carole Bernon, Jean-Pierre Georgé and Marie-Pierre Gleizes

• Real time detection of abnormal behaviors by using feedback from the medical staff.
• Detect anomalies through a linear regression of disparity values
• Is this another hyperparameter system? It could be looking for sensitivity of the system to hyperparameter

Risk-based Testing of Self-Adaptive Systems using Run-Time Predictions
André Reichstaller and Alexander Knapp

• Uses machine learning to explore the space that includes errors. It is a way of finding major(?) features in the state space
